CHAPTER 8: CABLE CONNECTION PARAMETER
8. CABLE CONNECTION PARAMETER
1000BASE-SX/LX networks only support full-duplex mode. The Switch based Media Converter breaks up TP and Fiber segments’
collision domain to extend the cabling distance.
UTP Cables: CAT5, or above CAT5e class UTP cables
UTP Cable Limitations: Max. Length up to 328 feet (100 m)
Fiber Cables:
- 1000BASE-SX: 50/125, 62.5/125, or 100/140μm multimode
- 1000BASE-LX: 8.3/125, 8.7/125, 9/125 or 10/125μm singlemode
