The post-amplifier modules come standard with LC/APC Duplex connectors.
Optical jumpers are sold separately to interconnect pre- and post-amplifier modules
and to interconnect to other equipment that may have other optical connector types.
WARNING:
Avoid damage to your eyes! Do not look into any optical connector while the
system is active. Even if the unit is off, there may still be hazardous optical
levels present.
