An Ethernet splitter takes advantage of the fact that 10MBit and 100Mbit Ethernet only use 4 wires, even though the cable (almost certainly) contains 8 wires. The splitter consists of two pieces (see picture): one is connected to each end of the existing cable, providing the appearance of two ports at each end. Each link has 4 dedicated wires, so there is no risk of packet collisions. Gigabit Ethernet does require all 8 wires, so 100MBit (full duplex) is the limit through a splitter; a Gigabit switch would be required to increase the bandwidth. Also, if your router only has one Ethernet port, then using a splitter is not an option. Ethernet splitter + Ought to be cheapest + Passive; doesn't require a power supply - Limited to providing one extra port, at 100MBit/s - Destination switch/router must have two free Ethernet ports 100MBit/s switch + Potential for many extra Ethernet ports - Requires some set-up Gigabit switch + Higher bandwidth - Most expensive - Requires the rest of the network (LAN) to support Gigabit to benefit Hub + Relatively cheap, but... - ...not significantly cheaper than switches - Very poor performance, especially as network load increases (due to collisions)

Providing commercial-grade Network wiring service throughout a business facility involves the installation of a collection of connectors, connecting hardware and cables using unshielded twisted pair (UTP), screened (foil) unshielded twisted pair (F/UTP), shielded twisted pair (STP), or multimode or singlemode fiber optics. Unshielded Twisted Pair Wiring UTP cables come in a variety of grades for applications from the work area in a call center to telecommunications rooms to connections to and inside data centers. Siemon Augment Category 6 UTP cable uses larger cable diameters to mitigate crosstalk in 10G BASE-T applications. Category 5e and 6 are also offered. Screened (Foil) Unshielded Twisted Pair Wiring Siemon’s Category 6A F/UTP system prevents alien crosstalk through a cable shield. The cable design resists deformation and allows less restrictive installation practices. The smaller cable diameter offers a greater pathway fill density. Connectors in flat, angled and keystone versions are designed with simple grounding in mind. Shielded with Foil Twisted Pair Wiring S/FTP cables are copper cables better suited for network wiring in buildings that are exposed to high electrical interference or frequent radio transmissions. Guaranteed to support 10G BASE-T since 1999, Siemon’s shielded Category 7 TERA is a standards approved connector that virtually eliminates crosstalk between pairs and between cables. The unique design of TERA supports cable sharing, making TERA suitable for a variety of applications. Fiber Optic Wiring Fiber optic network cabling is the most common network connection for data centers, though F/UTP and S/FTP are gaining popularity. Fiber optic cabling is available in singlemode and multimode forms. A mode is the path a ray of light follows while traveling down a fiber cable. As pictured, multimode fiber allows more than one mode of light. Common multimode core sizes are 50 µm and 62.5 µm. Singlemode fiber allows for only one pathway, or mode, of light to travel within the fiber. The core size is typically 8.3-10 µm. UTP – Network Wiring Diagrams that call for UTP, F/UTP and S/FTP copper cabling types can be used throughout local area networks (LAN). Copper cabling standards are designated as Category 5e, Category 6, Augmented Category 6, Category 7, Class D, Class E and Class F and FA (To learn more, read “Demystifying Cabling Specifications from 5e to 7A”). This numbering system refers to the specifications defined by committees of ISO, ATM, TIA, CSA, CENELEC and JSA/JSI. The ANSI / TIA / EIA-568 standard, for example, is a telecommunications cabling standard for commercial buildings covering Category 5e, 6 and 6A. As the categories build from 5e to 7, the speeds of data transfer across network wiring increases as does the headroom for advanced network applications. For example, while Category 5e network wiring is rated to 100 MHz, standards compliant Category 7 cables provide 600 MHz data transfer rates and Class FA go to 1000MHz. Structured Cabling Systems Network cabling and wiring systems rely on a variety of structured cable system components working in harmony. The weakest link in a cabling channel represents its highest performance. Some of the components of a cabling system include: patch panels for switching functions between router for incoming and outgoing lines, horizontal cables for in-wall installation, and patch cables to connect stand alone computers to outlets and outlets to telecommunications closets. For housing and storage of network wiring systems, products such as cable troughs, wireways, enclosure cables, rack accessories, and cabling cabinets are also installed. These components protect the wiring and equipment from dust, dirt, water, and oil while simplifying cable management.

Ethernet cables are used to connect computers to networks, modems, or routers via a wired connection. The cables transmit data through twisted pairs of copper wire or solid core wires in RJ-45 connectors. Twisted pair cables are made up of four twisted pairs of copper wire. In some cases only two pairs are used to transmit information, but in faster cables all four pairs are used. Wired connections are often more stable and reliable than wireless connections. Different types of cables are used for different applications and different distances. In most Ethernet cables, the signal degrades over distance. The type of cable used affects the network speed and connectivity, and it is therefore important to use the right cable for the right application. Choosing the right type of Ethernet cable depends on the network type and speed, the distance and terrain to be covered, and the cable's function. Shoppers can find Ethernet cables at PC shops and online. Types of Ethernet Cables A number of different types of Ethernet cables are available on the market today. The different types are most commonly identified according to category definitions, but they can also be differentiated by the types of plugs used. Ethernet Cable Categories Ethernet cabling categories are defined by the Electronic Industries Association and the Telecommunications Industry Association (EIA/TIA). Categories are defined according to each type of cable's performance, and the network speed and frequency (or bandwidth) it can support. The table below gives a brief description of the most common types of cabling available. Ethernet Cable Type Description Cat 3 Older networks worked with Cat 3 cable and this type of cable is no longer readily available. It supports 16 MHz bandwidth, 10 Mbps Ethernet connections, and can be used for voice and telephony. Cat 5 cable is backwards compatible with Cat 3 applications, but supports 100 MHz bandwidth and 10/100 Mbps Ethernet connections. Cat 5E is the enhanced version of Cat 5 and is most common. However, with constant increases in internet speeds, Cat 5E is becoming a budget option. Cat 5E helps to prevent electromagnetic interference and can support Ethernet connections of 10/100/1000 Mbps, and 100 to 400 MHz bandwidth. 1000 Mbps Ethernet is also known as Gigabit Ethernet. All four wire pairs in the cable are used. Cat 6 cables are backwards compatible with all other cables. They are like Cat 5E cables, but have larger gauge wires and work for Ethernet connections up to 10 Gbps. They support up to 250 MHz bandwidth. Cat 6 cables were developed with Gigabit Ethernet in mind. Those who are upgrading their network cables should consider installing Cat 6 as this will eliminate the need to upgrade again in the near future. When installing cables for 10Gbps Ethernet, Cat 6 cables can be used over distances of up to 185 feet, but Cat 6a should be used for distances up to 300 feet. Cat 7 cabling is also known as Class F. This fully shielded variety supports bandwidths of up to 600 MHz, but is not used for home networking. As mentioned above, Cat 5E cables are the most common and economical cables available, but Cat 6 should be considered when upgrading a home network. Ethernet Cable Plugs Ethernet cables come with a plug at each end. The type of plug or connection determines the cable's use. The typical, most common cable is known as a straight-through cable. If one holds the ends side by side one can see that the smaller colored wires that make up the cable are in the same color order from left to right. These cables are used to connect two different devices, for example a PC to a hub or switch, or a router to a switch. A crossover cable has different plugs on either end. This type of cable is used to connect two similar devices to one another without a switch in the middle. The middle component usually performs the crossover function. In other words, a crossover cable can be used to connect a PC directly to another PC, or one switch to another. Ethernet Cable Construction Ethernet cables are constructed in a number of ways. Simpler constructions are usually needed for home networking, but it is important to understand the terms used in item descriptions. Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP) Cables As mentioned previously, Ethernet cables are usually made up of four twisted pairs of copper wire. Cables can be further categorized as unshielded twisted pair ( UTP ) or shielded twisted pair ( STP ). Shielded twisted pair cables are designed to prevent interference from other devices and generally yield higher performance. However, they are seldom used in, or necessary for, home networking. They are also more expensive than UTP cables. Stranded and Solid Core Cables Ethernet cables used in home networking are usually stranded rather than solid. This means that each cable is made up of thin individual strands of copper wire that add up to 22 to 24 gauge thickness when twisted together. This type of cabling is best for extreme bends and patch cables. Solid core cables have one solid 22 to 24 gauge copper wire. They transmit signals more easily and are best for long runs, but are not flexible. Too much bending can lead to broken wires. They are commonly used inside walls and where a network is installed during the construction phase of a building. Ethernet Cable Coatings Ethernet cables are usually coated with PVC. However, as PVC releases toxic fumes when burning, PVC encased cables are seldom used in air handling spaces. In fact, some local fire codes prohibit its use in these areas. Plenum rated cables are used instead. Plenum is not a type of coating; these cables are usually coated with flame retardant smoke reducing PVC or Teflon. The name comes from the construction term for a building's air handling space (plenum). Plenum rated Ethernet cables are seldom used in home networking and are generally significantly more expensive than PVC coated cables. Armored, outdoor, aerial duct, and direct burial cables offer additional protection against the elements and can be used in more rugged environments. They protect against water or foreign matter entering the cable housing or coming into contact with the cable's wiring. Additionally, these durable cables feature corrosion resistance, and prevent damage from abrasion. They come with a variety of tougher coatings. However, these cables are seldom needed for home networking. Choosing the Right Ethernet Cable To choose the right category of Ethernet cable, one must determine one's connection speed. Cat 5 or 5E is adequate for connections up to 100 Mbps, but Cat 6 cable should be considered for faster connections. The next step is to determine the length of cable needed. Signal tends to degrade in longer cables, and shorter cables are faster with a clearer signal. For distances of 100 m or more one should consider Cat 6 or 6a. Cat 5E is best for 100 m or less, and Cat 5 for distances below 20 m. Lastly, one should select the appropriate plug type. Altogether, the most common cables used for home networking are Cat 5E or 6, straight-through, stranded, unshielded twisted pair, PVC coated cables.

On May 22, Harford County, Maryland held a press conference to announce its high-speed fiber optic based network, which will connect government buildings, schools, and libraries while reducing costs. The fiber optic cable, known as HMAN, or Harford Metro Area Network will allow greater broadband access to residents. According to Ted Pilbil, director of the county’s ICT department, the HMAN will “upgrade the county’s computer network and serve as a communications backbone” for Harford. As part of the fiber optics solution, Cisco helped guide the County into a design that was within its budget and met all its technical needs. More than 100 miles of fiber optic has connected approximately 100 institutions around the county. The design included a Metro Ethernet solution based on the ASR9K platform, which has allowed the County to replace its expensive leased lines with a wholly owned fiber optic network managed by the county. The network has the ability to add Dense Wave Division Multiplexing (DMDW) optical technology to further expand the network capacity by a factor of 40x with additional equipment. Cisco’s flexible design allowed the County to reduce costs while providing high-speed connectivity to local schools, libraries, public safety offices, and economic development zones. The HMAN has great potential to provide economic opportunities and bring business into Harford County. One such opportunity is the presence of “dark fiber.” In essence, dark fiber is when cables are not activated, which can allow a company to create its own private network. Furthermore, business that could not previously access broadband service from traditional carriers – whether due to location or cost – can now buy into a cost-effective, high-speed network. The data will move faster and with greater reliability and flexibility. Alongside businesses, city and county government will also be linked on the broadband highway, offering endless possibilities for teleconferencing, data sharing, and video communications. Furthermore, HMAN will open opportunities for additional infrastructure for primary, secondary, and higher education.

Multi-function Serial Ethernet Redirection Software Multifunction serial to ethernet (and ethernet to serial) interface software. Easily access a serial device via a TCP/IP or UDP network or redirect Ethernet/IP data to real or “Virtual” RS232 serial ports. This allows you to use existing Windows-based serial RS232 communications software to send and receive data across any TCP/IP network. TCP/Com software is extremely simple but powerful. It can be used to solve a wide variety of device interfacing and RS232 or TCP/IP conversion problems, such as the following: Turn a PC into a Serial Device Server (Terminal Server) Send or receive data over a TCP/IP port with any serial communications program Open COM ports located on another computer in your network as if they were local Use Ethernet network (or the Internet) as a giant serial RS232 cable (Serial Tunneling) Feed data from one physical RS232 port to multiple RS232 serial communications applications Map a TCP/IP port to a different TCP/IP port Use TCP/Com as a Serial Device Server Share serial devices over a network (or even the internet) Use TCP/Com as a Virtual Serial Port Splitter Cable Windows does not allow multiple programs to access the same COM port. Bypass this restriction by using TCP/Com to split a single COM port into multiple virtual COM ports. This allows all your serial communications programs to access the same data. Intuitive Multi-Document Interface In the TCP/Com window just select the com port number and the serial communications parameters for your serial device and enter an IP address and a socket number. Then activate! It's that easy! Com port data will appear at the IP address and data from an IP port will appear at a real or virtual com port. Recent Updates (released March 2014) now allows users to name individual session windows to better manage multiple connections. A bug fix that addresses the remote pings feature is also included.

Custom Search Common Ethernet network cable are straight and crossover cable. This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called RJ45 connector. The cable can be categorized as Cat 5, Cat 5e, Cat 6 UTP cable. Cat 5 UTP cable can support 10/100 Mbps Ethernet network, whereas Cat 5e and Cat 6 UTP cable can support Ethernet network running at 10/100/1000 Mbps. You might heard about Cat 3 UTP cable, it's not popular anymore since it can only support 10 Mbps Ethernet network. Straight and crossover cable can be Cat3, Cat 5, Cat 5e or Cat 6 UTP cable, the only difference is each type will have different wire arrangement in the cable for serving different purposes. Straight Cable You usually use straight cable to connect different type of devices. This type of cable will be used most of the time and can be used to: 1) Connect a computer to a switch/hub's normal port. 2) Connect a computer to a cable/DSL modem's LAN port. 3) Connect a router's WAN port to a cable/DSL modem's LAN port. 4) Connect a router's LAN port to a switch/hub's uplink port. (normally used for expanding network) 5) Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using normal port. If you need to check how straight cable looks like, it's easy. Both side (side A and side B) of cable have wire arrangement with same color. Check out different types of straight cable that are available in the market here. Crossover Cable Sometimes you will use crossover cable, it's usually used to connect same type of devices. A crossover cable can be used to: 1) Connect 2 computers directly. 2) Connect a router's LAN port to a switch/hub's normal port. (normally used for expanding network) 3) Connect 2 switches/hubs by using normal port in both switches/hubs. In you need to check how crossover cable looks like, both side (side A and side B) of cable have wire arrangement with following different color . Have a look on these crossover cables if you plan to buy one. You can also find more network cable choices and information from Comtrad Cables. In case you need to make a crossover cable yourself! You can use this crimper to do it. Lastly, if you still not sure which type of cable to be used sometimes, try both cables and see which works . Note : If there is auto MDI/MDI-X feature support on the switch, hub, network card or other network devices, you don't have to use crossover cable in the situation which I mentioned above. This is because crossover function would be enabled automatically when it's needed.
