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 LC.
Gigabit Fiber with multi-mode LC SFP module
Gigabit Fiber with single-mode LC SFP module

The following table lists the types of fiber that GSW-1291 supports and part
of these models are available upon request.
