2-4 TranScend Chassis – Operation Manual
The AGC EDFA detects the alarms and reects them on the front panel LEDs based on the following schema.
LED Location Trigger Events
Top Optical input power
Optical output power
Gain
Module temperature
Bottom Disable
Example #1: The optical input power is at a level that indicates a major alarm, but the rest of the attributes are
normal. The top LED associated with the slot shall be observed as “red”.
2.1.10 Transceiver
The Transceiver (also known as MDU) detects the alarms and reects them on the front panel LEDs based on the following
schema.
LED Location Trigger Events
Top Laser Temperature
Laser Power
Optical Input Power
Module temperature
Bottom RF
Example #1: The optical input power is at a level that indicates a major alarm, but the rest of the attributes are
normal. The top LED associated with the slot shall be observed as “red”.
2.1.11 High Sensitivity Opto-Stacker
The High Sensitivity Opto-stacker is a dual wide plug-in that detects the alarms and reects them on the front panel LEDs
based on the following schema.
LED Location Trigger Events
Top Laser Temperature
Optical Input and output Power
Module temperature
Bottom Lock
Example #1: The optical input power is at a level that indicates a major alarm, but the rest of the attributes are
normal. The top LED associated with the slot shall be observed as “red”.
2.1.12 Direct Forward Transmitter (DFB Tx)
The Direct Forward Transmitter detects the alarms and reects them on the front panel LEDs based on the following
schema.
LED Location Trigger Events
Top Laser Temperature
Optical Input Power
Module temperature
Bottom RF
Example #1: The optical input power is at a level that indicates a major alarm, but the rest of the attributes are
normal. The top LED associated with the slot shall be observed as “red”.
