Data Sheet
1
The AT10GC receiver consists of an avalanche photodiode,
alow-noise preamplifier and a precision NTC thermistor in a
hermetic coplanar package with 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 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:
•Sensitivity, -26.5dBm typical
•Low capacitance high speed InGaAs
APD photodetector
•Supports FEC rates up to 10.709Gb/s
•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
10Gb/s surface mount coplanar APD
preamp receiver for low OSNR applications
