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 better, with a maximum length of
100 meters.
⇒ Gigabit Ethernet TP network connection
⎯ The grade of the cable must be Cat. 5e or better, with a maximum length of
100 meters. Cat. 6 is recommended.
2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module
Fiber optic media is more complex and comprehensive compared to TP
cabling. There are two categories of fiber, multimode (MM) and singlemode (SM).
The various Gigabit singlemode fiber specification types are categorized into
several classes by the distances they support. These categories are 1000BaseSX,
1000BaseLX, 1000BaseLH, 1000BaseXD, and 1000BaseZX. From the viewpoint of
connector type, the main types used in SFP modules are LC and BIDI LC.
⎯ Gigabit Fiber with multimode LC SFP module
⎯ Gigabit Fiber with singlemode LC SFP module
⎯ Gigabit Fiber with BiDi LC 1310 nm SFP module
⎯ Gigabit Fiber with BiDi LC 1550 nm SFP module
The following table lists the types of fiber that Signamax supports; those not
listed here are available upon request.
