P-50A
Product Bulletin (Target) • February 2002
• Ultrafast PIN detector module
• High bandwidth, 50 GHz
• 0.65 A/W responsivity
• 8 ps risetime
• Front-end for 40 Gb/s receivers
• 50 ∑ internal termination
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.
