The
P-50A
is an ultrafast, InGaAs PIN
photodetector designed as an O/E front-
end for OC-768, 40 Gb/s, RZ and NRZ
systems. The proprietary, back-illuminated
semiconductor diode design optimizes
speed and sensitivity for both 1310 nm
and 1550 nm wavelengths, while the
internal, ceramic waveguide design
assures a clean pulse response necessary
for low group-delay, time-domain, digital
applications.
The detector is mounted in a compact
8-pin butterfly-style package with an
Anritsu-V output connector with 50Ω
internal termination for low output
VSWR, and standard single-mode input
fiber. The hermetic module is Telcordia
compliant.

Application Notes
Electrostatic discharge (ESD) will cause permanent
damage to the product. Please avoid any ESD to the
input pins or output connector. Use standard ESD
protective equipment when handling this product.
Temperature and fiber restrictions are as follows:
Lead soldering: 250°C for no more than 10 seconds
Fiber feed-though tube: 120°C
Fiber pull force: 10 N
Fiber bending radius: 1 inch or less
Exceeding these conditions can cause permanent
damage to the device.
