OPERATIONAL SETUP - TRANSMITTER
The DFB Laser Transmitter included with the FRMUC/T-6940 has been adjusted at the factory for the proper
optical modulation index provided the RF levels are in the range mentioned above. No further adjustment to the
transmitter is required.
The optical power of the Laser Transmitter has been set at the factory at 3mW. No further adjustment to the
transmitter is required. If the optical power is measured and found to be much less than 3mW, optical connector
cleaning may be required.
The Laser Transmitter has two DC test points. One is for laser current and is scaled at lV per 50mA. The other
is for optical output power at the laser and is scaled at 1V per mW. It recommended that these two test points
be measured (with a DMM) and that their readings be retained as historical data.
