TDM4E LEDs

TheTDM4E LEDs provide information about its operating status. The Gigabit

Ethernet connection is typically equipped on the remote receiverside with a fixed

clock rate of 1250 mbit/s. A complete loss of optical signal on the remote receiver

causes the remote laser to automatically shut down.

Table1-8 describes the functions of each LED. If the system is operational and all

interfaces are properly connected, all active TDM4E receive and transmit LEDs

are continuously on.
