O/E front-ends requiring flat frequency
response. The back-illuminated photodiode
design optimizes speed and sensitivity for
the 1200 nm through 1650 nm wavelength
range. The internal waveguide design
assures a flat frequency response necessary
for analog applications.

The detector is available in a compact
3-pin package with either a K output
connector or an RF feed-through pin for
direct soldering to circuit boards. Input
via a single-mode fiber is standard. The
hermetic module is Telcordia compliant.
