12 Gb/s PIN
Preamp Receiver
The module consists of a PIN photodetector, a low noise
preamplifier, a connectorized single-mode fibre pigtail
(for coupling light into the photodetector), an SMP electrical
output connector, and a hermetic metal package.
Optimized for use in 10.66 Gb/s and 12 Gb/s Ultra Long Haul
applications using RZ Modulation.

Absolute Ratings
Notes:
1) The operating temperature is defined as the temperature of the module case.
2) The rating is referred to ambient temperature.
3) The optical level that causes no damage to the module. However, the electrical and optical performance specified
in this document may not be guaranteed.
4) The receiver may be damaged if not powered up and powered down in the correct order. When powering up the
device, turn on PIN bias (Vpd) first, then positive supply (Vcc). Power down in reverse order.
