Linksys DSSXFXSC, DSSXFXST manual Fiber Optic Modules, 412/1330

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:

Distance (m/ft) Cable Type Module in Switch A Module in Switch B

412/1330	Multi-Mode	Any ST or SC-Type
(Half Duplex)	62.5/125uM	100BaseFX Fiber
	Fiber Optic Cable	Optic Distance Extender
2000/6560	Multi-Mode	Any ST or SC-Type
(Full Duplex)	62.5/125uM	100BaseFX Fiber
	Fiber Optic Cable	Optic Distance Extender

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.
