9.6 Tbit/s DWDM equipment's been created A 100 Gbit/s signal has been transmitted for a distance of 4,250 km

MS-400E aggregating transponder

Transmits 4×100 Gbit/s client signals in two subcarriers DWDM channel 2xDP-16QAM

  • Transmits up to 4 client signals 100GE (103.125 Gbps) or OTU4 RS FEC (111.81 Gbps)
  • SD-FEC 15% and 25% error correction algorithm
  • Reconfigurable in C-band laser
  • 2xDP-16QAM Line interface/flex rate

Aggregating transponder (muxponder) combines 4×100 Gbit/s client channels and transmits them in a two DWDM channels. The MS-400E, converts data into the OTN format and uses the new coherent SDFEC error correction.The laser with a reconfigurable according to ITU-T 100 GHz enables organizing up to 48 DWDM channels 400G within the C-band according to ITU-T 100 GHz. Supports two individual line-side channels and each channel can be programmed to 100G PM-QPSK, 50G PM-8QAM and 200G PM-16QAM for optimization of reach versus capacity. Transponder supports both differential phase and absolute phase for all the modulation formats.
