DESCRIPTION
The Avalanche Photo-Diode Receiver Evaluation Board consists of a key avalanche photo-receiver, AT10GC, which integrate a low-noise preamplifier and a precision NTC thermistor in a hermetic coplanar package. Differential outputs are provided to improve noise rejection for enhanced sensitivity. It has been optimized for use in 10Gb/s metro applications, using NRZ modulation, with or without FEC, at data rates up to 10Gb/s.
FEATURES
Sensitivity, -26.5dBm typical
Up to 10Gb/s with C and L band
1000mVpp differential output voltage
APPLICATIONS
Metro Optical Transmission
Large Capacity Data Center Interconnection
