Technical content

The ATV10GC receiver consists of an avalanche photodiode, a low-noise preamplifier, a MEMS variable optical attenuator (VOA), 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 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, -26.5dBm typical
  • Integrated MEMS VOA extends overload beyond +10dBm
  • Low capacitance high speed InGaAs APD photodetector
  • Supports FEC rates up to 10.709Gb/s
  • Best in class power consumption, only 350mW
  • Designed to exceed the environmental requirements of Telcordia GR-468-CORE
  • RoHS 5/6 compliant Applications:
  • Client or line side links
  • DWDM TDM transponder applications 10Gb/s surface mount coplanar APD preamp receiver with integrated MEMS VOA ATV10GC
