7 Special ParBERT Systems Installing Optical Modules
7-20 Agilent 81250 ParBERT Installation Guide, May 2004
The E4882A lightwave receiver consists of a one-slot module which has
one optical input and one electrical output connector. The latter is to be
connected to the input of the 45G DEMUX module.

The E4883A lightwave transmitter is a two-slot module. Its electrical
DATA INPUT is to be connected to the output of the 45G MUX module.
To install the E4883A transmitter:
1 If you wish to use the built-in DFB laser, use a PMF cable and connect
the INTERNAL LASER OUTPUT to the LASER INPUT.
To use an external light source, connect this to the LASER INPUT.
The transmitter modulates the laser light it receives at LASER INPUT.
2 In addition, the E4883A lightwave transmitter requires a clock signal.
Connect its RZ CLOCK IN to the 10.8 GHz OUTPUT of the MUX module.
Do not look directly into the optical connector or the open end of a
connected fiber when the laser is active.
