Data Sheet
1
The AT10XGC receiver consists of an avalanche photodiode,
alow-noise preamplifier and a precision NTC thermistor in a
hermetic coplanar packagewith a connectorized single-mode
fiber pigtail. Differential outputs are provided to improve noise
rejection for enhanced sensitivity. It has been optimised for
use in 10Gb/s metro or long-haul applications, either as a
discrete device or within a transponder, using NRZ
modulation, with or without FEC, at data rates up
to 10.709Gb/s.
Features:
High sensitivity, -28.5dBm typical
Low capacitance high speed
InGaAs APD photodetector
Supports FEC rates up to 10.709Gb/s
Best in class power consumption, only 300mW
Designed to exceed the environmental requirements
of Telcordia GR-468-CORE
RoHS 5/6 compliant
Applications:
Client or line side links
300 pin LR transponder applications
Yellow fiber pigtail for MSA compliance
High Sensitivity 10Gb/s surface mount
coplanar APD preamp receiver
