40 to 870 MHz CATV amplifier systems
DESCRIPTION
Hybrid high dynamic range optical receiver amplifier
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 1290 to 1600 nm, a terminal to monitor the PIN
diode current and an electrical output with an
impedance of 75
.
HANDLING
Fiberglass optical coupling: maximum tensile strength = 5 N;
minimum bending radius = 35mm.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134)
