10 Gb/s Coplanar PIN
Preamp Receiver
The module consists of a PIN photodetector, a low noise
preamplifier, a connectorized single-mode fibre pigtail and a
hermetic metal package with coplanar output. Optimized for
use in 10 Gb/s long haul applications, either as a discrete
device or within a transponder, using NRZ Modulation.
