Optical unit connection: Connect the optical transmission line to the T and R receptacles. Note which cable channel goes to T or R by noting cable imprint. On the other end, reverse the connection.

Notes: Some fiber types in short distance applications may overload the receiver. If other than coax cable is used, use balun (impedance matching transformer).
