Ethernet twisted pair cable
Introduction
An Ethernet twisted pair cable consists of four pairs of insulated copper wires twisted together. Every wire uses a different color, and has a diameter of about 1 mm (0.04 in). A pair of twisted copper cables can cancel the electromagnetic radiation of each other, and reduce interference of external sources. An Ethernet twisted pair cable typically transmits analog signals and is advantageous in transmitting data over shorter distances. It is the commonly used transmission media of the Ethernet. The maximum transmission distance of the Ethernet twisted pair cable is 100 m (328.08 ft). To extend the transmission distance, you can connect two twisted pair cable segments with a repeater. At most four repeaters can be added, which means five segments can be joined together to provide a transmission distance of 500 m (1640.42 ft).
Ethernet twisted pair cables can be classified into category 3, category 4, category 5, category 5e, category 6, and category 7 cables based on performance. In LANs, category 5, category 5e, and category 6 are commonly used.
Table7-2 Description for commonly used Ethernet twisted pair cables
Type |
Description |
Category 5 |
Suitable for data transmission at a maximum speed of 100 Mbps |
Category 5e |
Suitable for data transmission at a maximum speed of 1000 Mbps |
Category 6 |
Suitable for data transmission at a speed higher than 1 Gbps |
Based on whether a metal shielding is used, Ethernet twisted pair cables can be classified into shielded twisted pair (STP) and unshielded twisted pair (UTP). An STP cable provides a metallic braid between the twisted pairs and the outer jacket. This metallic braid helps reduce radiation, prevent information from being listened, and eliminate external electromagnetic interference (EMI) of external sources. STPs have strict application requirements and are expensive although they provide better EMI prevention performance than UTPs. So in most LANs, UTPs are commonly used.
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure7-2 shows the pinouts of an RJ-45 connector.
Figure7-2 RJ-45 connector pinout
|
NOTE: The RJ-45 Ethernet ports on the device use category 5 or above Ethernet twisted pair cables for connection. |
EIA/TIA cabling specifications define two standards, 568A and 568B, for cable pinouts.
· Standard 568A—pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown solid.
· Standard 568B—pin 1: white/orange stripe, pin 2: orange solid, pin 3: white/green stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: green solid, pin 7: white/brown stripe, pin 8: brown solid.
Ethernet twisted pair cables can be classified into straight-through and crossover cables based on their pinouts.
· Straight-through—The pinouts at both ends are T568B compliant, as shown in Figure7-3.
· Crossover—The pinouts are T568B compliant at one end and T568A compliant at the other end, as shown in Figure7-4.

To ensure normal communication, the pins for sending data on one port must correspond to the pins for receiving data on the peer port. When both ports on the two devices are MDI or MDIX, use a crossover Ethernet cable. When one port is MDI and the other is MDIX, use a straight-through Ethernet cable. To summarize, straight-through and crossover cables connect the following devices:
· Straight-through cables connect devices of different types—For example, router to PC and router to switch.
· Crossover cables connect devices of the same type—For example, switch to switch, router to router, and PC to PC.
If an RJ-45 Ethernet port is enabled with MDI/MDIX autosensing, it can automatically negotiate pin roles.

NOTE: The RJ-45 Ethernet ports on the device support MDI/MDIX autosensing. |
Making an Ethernet twisted pair cable
1. Cut the cable to a required length with the crimping tool.
2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector.
3. Untwist the pairs so that they can lay flat, and arrange the colored wires based on the wiring specifications.
4. Cut the top of the wires even with one another and insert the wires into the RJ-45 connector. Make sure the wires extend to the front of the RJ-45 connector and make good contact with the metal contacts in the RJ-45 connector and in the correct order.
5. Crimp the RJ-45 connector with the crimping tool until you hear a click.
6. Use a cable tester to verify the connectivity of the cable.
Optical fiber
Optical fibers feature low loss and long transmission distance.
Optical fibers can be classified into single-mode fibers and multimode fibers. A single-mode fiber (with yellow jacket) carries only a single ray of light; a multimode fiber (with orange jacket) carries multiple modes of lights.

Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient. There are multiple types of fiber connectors. Figure7-5 and Figure7-6 show an LC connector and an MPO connector, respectively.
Follow these guidelines when you connect an optical fiber:
· Before connecting an optical fiber, make sure the connector and cable type match the interface module.
· Before connecting an optical fiber, use dust free paper and absolute alcohol to clean the end face of the fiber connector. You can brush the end faces only in one direction.
· Never bend or curve a fiber.
· If the fiber has to pass through a metallic board hole or bend along the acute side of mechanical parts, the fiber must wear jackets or cushions.
