Linksys EF2H24, EF2H16 manual Maximum distance 0f 208 meters

Instant EtherFast II Series

When using fiber, the noise loss has to be calculated. Also, always use the same type of fiber connector (SC or ST) for your fiber cables. If you are using ST-type connectors and you introduce an SC-type connector module, an SC to ST converter has to be obtained, or the ST connector may be replaced by an SC Connector

Note: Changing connectors should be done professionally, using the proper tools. If you have never worked with fiber cabling, seek the help of an experienced professional.

The following table shows the distance limitation when connecting the Linksys Fiber modules:

Distance (meters/ft)	Cable type	Module in Hub A	Module in hub B
208/672	Multi-Mode	EF2HSC or EF2HST,	EF2HSC, EF2HST
	62.5/125uM	SC or ST Type 100BaseFX	SC or ST Type
	Fiber Optic Cable	Fiber Distance Extender	Fiber Transceiver Module
412/1330	Multi-Mode	EF2HSC or EF2HST	EF2HSC, EF2HST
(Half Duplex)	62.5/125uM	SC or ST Type	SC or ST Type
	Fiber Optic Cable	Fiber Distance Extender	Fiber Distance Extender

10/100 Hubs

The following illustration is an example of how to connect two rack-mount- able EtherFast II 10/100 Hubs together using fiber optic cabling. Notice that both hubs are equipped with 100BaseFX 1-Port Distance Extender modules. The distance extender modules allow data to be sent up to 208 meters (672 feet).

For a full explanation of fiber optic cabling distance rules, see the chart on page 12.
