What industry standards body and standards series numbers do you need to reference for Ethernet applications and cabling?
a. The Commercial Building Telecommunications Cabling Standard, known as ANSI/TIA/EIA-568-C.
b. The IEEE maintains the industry standards for Ethernet protocols, which is part of the 802.3 series of standards. There is an increased need for speed these days and network technology designers are planning to support data rates of up to 100Gbps.
2. What are the different types of Category 6 cable and what should be recommended for this network?
a. 10Gbps @ 100 Meters – There are two types of Category 6 cable, regular Category 6, and Category 6A (or Augmented Category 6). It would be my recommendation to use 6A or Category 7. Since we have to support 10Gbps over a maximum of 100 meters, I would recommend using Category 6A, or Category 7 cabling.
3. What cable would you recommend to offer the best shielding performance?
a. Full of stray EMI, UTP not an option, and customer wants to ensure capability to operate at 10GBase-T.
i. I could recommend a Screened Twisted-Pair Cable or Screened Shielded Twisted-Pair Cable.
4. What type of cable would you use for
a. Horizontal Spaces – Plenum cables. Solid Conductor Wire.
b. Vertical Spaces – You should use riser-rated cabling in vertical spaces or where flexibility is important. Stranded-conductor wire.
5. What would you look for in trying to find fault if you had the following failures:
a. NEXT and FEXT problems in 1Gbps links – Make sure that the twists in the cables have not been undone and check the coupling. Also, you can reduce FEXT by using rectangular-shape resonators. Another solution that the book mentions is to use shorter cables.
b. Difficulty meeting 10Gbps performance requirements – Check electromagnetic interference by using a device that can detect the amount of interference. You can move the cables away from the source of the interference. Other solutions include using cables that are properly shielded or using fiber optic cable.
