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
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.
⎯ Gigabit Fiber with multi-mode LC SFP module
⎯ Gigabit Fiber with single-mode LC SFP module
⎯ Gigabit Fiber with BiDi 1310nm SFP module
⎯ Gigabit Fiber with BiDi 1550nm SFP module
The following table lists the types of fiber that we support and those else not listed here are
available upon request.
