The OS8740230W is a hybrid high dynamic range optical receiver ampli-
fier module. Two of the module pins are for connection to 24V (DC), one
for amplifier supply voltage, the other for the PIN diode bias. The module
contains a single mode optical input suitable for wavelengths from
1290nm to 1600nm, a terminal to monitor the PIN diode current, and an
electrical output with an impedance of 75. Fiberglass optical coupling;
maximum tensile strength=5N; minimum bending radius=35mm.
