Fiber Optic Modules

There are different 100BaseTX fiber add on modules available switches:

Modules with ST or SC-Type Fiber Optic Distance Extender Ports (can used on

the back of all the switches):

DSSXFXST

ST-Type Single-Port Fiber Module

DSSXFXSC

SC-Type Single-Port Fiber Module

The following chart shows the distance limitations when using any of the above

fiber modules:

When using fiber, 

noise loss

must be accounted for.  Noise loss means the

integrity of your data transfer over fiber optic lines, which occurs in fiber con-

nections, e.g. where the fiber is converted to copper lines in the switch, or

where the fiber cabling is not properly crimped on its connector tips.  For

example, if your fiber cabling has ST connectors and you have an SC-type fiber

module, an SC to ST converter must be used.  Otherwise, you can also replace

the ST connector with an SC connector. 

If you have never worked with fiber cabling before, consult a networking pro-

fessional who is familiar with fiber cabling.

NOTE:

Changing connectors must be done professionally, and proper

tools must be used.  If you have never worked with fiber cabling, con-

sult the help of a professional who is familiar with fiber.
