2-1-2. Cabling Requirements

To help ensure a successful installation and keep the network performance good,

please take a care on the cabling requirement. Cables with worse specification will render the
LAN to work poorly.

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.



Gigabit Fiber with multi-mode LC SFP module



Gigabit Fiber with single-mode LC SFP module



Gigabit Fiber with BiDi SC 1310nm SFP module



Gigabit Fiber with BiDi SC 1550nm SFP module

The following table lists the types of fiber that we support and those else not

listed here are available upon request.
