2-1-2-1. Cabling Requirements for TP Ports 
 
⇒  For Fast Ethernet TP network connection 
  The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 
100 meters. 
⇒  Gigabit Ethernet TP network connection 
  The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 
100 meters. Cat. 5e is recommended. 
 
2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module 
It is more complex and comprehensive contrast to TP cabling in the fiber 
media. Basically, there are two categories of fiber, multi mode (MM) and single 
mode (SM). The later is categorized into several classes by the distance it supports. 
They are SX, LX, LHX, XD, and ZX.  From the viewpoint of connector type, there 
mainly are LC and BIDI SC.
