Transponder TQ-3FS

Transmission of signals with a linear speed of 2.67 Gbit/s in the OTU1 channel with FEC G.709

  • Useful for organizing 1+1 and ring protection
  • FEC G.709 error correction algorithm
  • OTN OTU1 line interface
  • OSNRT = 8.5 dB (0.1 nm, BER = 10 -12)

Quadruple transponder TQ-3FS combines 2 client GE streams, STM-1/4 streams into a linear OTU1. The TQ-3FS contains four transponders, each of which transmits one GE client stream, TM-1/4/16 to the OTU1 stream. Transponders in the TQ-3FS are working and configured independently: a different combination of client streams is possible. TQ-3FS is only available with FEC G.709.
