moisture and ultraviolet light. When installing cable in walls, ceilings and under floors, it is important to use cables that meet the local code requirements (usually based on the NFPA's National Electric Code). The three basic ratings for both cable types are general purpose, riser and plenu...
There are two types of serial interface: asynchronous and synchronous. With an asynchronous interface or SCI, data travels in well-defined frames. A frame is a single, non-divisible packet of bits. The frame includes certain information (for instance, data) and some overhead, such as control...
Backward compatibility exists between Cat 6 and Cat 7 cables. They will not, however, provide you with the claimed speeds if you are using a slower ISP (or router). Simply explained, if your router’s maximum internet speed is 100 Mbps, a Cat 6 ethernet connection will not increase that ...
Ethernet connectors use a specialized design with eight pins that must lock into place, typically called an 8P8C connector. Ethernet cables have a couple of different types of 8P8C connectors, and knowing the difference will help you understand different Ethernet categories more clearly: ...
1000BASE-LX(multimode/singlemode fibre cables). These can be used for longer runs, such as on backbones and campus networks. Single-mode fibres are covered by the long-wavelength standard, and provide for greater distances. External patch cords are used to reduce DMD. Typical lengths are: 62...
When you need crossover cables is often explained, but why is seldom explained. It has to do with the copper (often referred to as Ethernet) wire itself. In copper wiring, there are four pairs of two wires (eight total wires). The pairs are numbered 1-4. T...
This is why a decent cable should be used, and Category 6 cables are recommended. Take precautions. According to the power loss formula, Q=I2Rt, the minimal current and minimum resistance are necessary to make the complete power supply process the best in order to reduce the loss between ...
It makes me curious to what the actual BER is in reality with decent cables that don’t come close to 100 meters. Of course, there’s still the power consumption issues and other drawbacks that Greg mentioned when compared to fiber (or coax). However, it’ll be good to have another ...
