Technical content

The AT3SGCC is an optical receiver offering optimum sensitivity and overload performance for OC-48 optical transport systems. The hermetic packaged fiber pigtailed receiver contains an avalanche photodiode, an AGC low noise pre-amp and a precision thermistor. The RF coplanar data outputs from the package provide differential noise rejection for improved sensitivity. The product has been optimized for use in metro applications, either as a discrete device or within a transceiver, using NRZ modulation, with or without FEC, at data rates up to 2.7Gb/s. The combination of a high performance avalanche photodiode, (APD), low noise AGC pre-amp and RF coplanar package provides unmatched performance for maximising transmission distance. The AGC low noise pr e-amp is well suited to dynamic threshold level decision circuitry often used to maximise overall receiver chain performance. Features:

  • High sensitivity, -35.0dBm typical
  • Wide dynamic range performance to -3dBm
  • MSA coplanar receiver package
  • Differential data outputs
  • +3.3V operation
  • RoHS 5/6 compliant Applications:
  • OC-48 DWDM optical transport systems
  • OC-48 DWDM metro and long haul systems
  • STM-16 SDH or OC-48 SONET systems 2.5Gb/s High Sensitivity coplanar APD preamp receiver AT3SGCC
