Installing the EDR Transmitter
The transmitter module uses the same style housing as the optical receivers and
transmitters, except that it uses double-wide module housing. As such, it occupies
two standard transmitter positions in the node lid.
If your EDR transmitter comes without OPM module installed, you need to order
the fiber jumper and the OPM module from our sales representatives, and perform
the following steps to install the OPM module and connect the fiber jumper to the
installed OPM module before installing the EDR transmitter.
To Install the OPM Module in the EDR Transmitter
CAUTION:
The OPM modules are electro-static sensitive devices. Always use an ESD wrist
strap or similar individual grounding device when handling OPM modules or
coming in contact with modules.
1. Connect the blue LC connector to the transmit bore of the OPM module before
installing the module. Refer to the EDR OPM and LCM section on page 238 for
details for the OPM module.
2. Close the bale-clasp before inserting the OPM module.
3. Connect the blue LC connector to the transmit bore of the OPM module.
4. Line up the OPM module with the port, and slide it into the port.
