The Laser Transmitter Rack
This rack is located
in the receiver cabin. There are 7 racks.
Unit # 1 is equipped with a 220V power supply for standalone tests.
When 220V is not present, the unit takes its power from the
Socapex connector.
Unit # 7 is equipped with previous generation lasers so the electrical
performance may not be exactly the same.
A microcontroller board provides remote monitoring and records
the aging of the laser diodes. There is no control on this rack.
The documentation can be read here.
