Technical content

The AT10GC receiver consists of an avalanche photodiode, a low-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 AT10GC
