B.1 CABLES AND CONNECTORS
The 3F00-01 and 3F55-01 use standard fiber optic cables for connecting
the MIC A and MIC B cables. The Optical Bypass Switch (OBS) uses an
RJ-11 connector (an AMP 6-pin shielded modular plug for the OBS is
recommended.) Pinouts for the connector at the end of the OBS cable are
provided in Table B-1 below.
