media converter / fiber optic
The CSEFE chassis card is a speed selectable copper to fiber media converter. The ability to select the speed of converter allows for easy migration from a 10 Mbps network today to a 100 Mbps network in the future. This converter is a true Layer 1 device as both the copper and fiber ports operate at the same speed setting (i.e. 100Base-T to 100Base-FX). For 10 Mbps applications, these devices must be used in pairs.
