Product Description

M2H20 is a 200G OTN Transponder/Muxponder board capable of packaging and de-packaging functions from 100G/40G/10G services to OTUC2. The client-side port allows access to 2 channels of 100G services, 4 channels of 40G services, or 20 channels of 10G services. Typical client services include 100GE, 40GE, and 10GE.

The line-side port supports either 1 channel of 200G OTUC2 signal or 1 channel of 100G OTU4 signal. It supports 8/16QAM modulation for 200G OTUC2 line mode, PM-QPSK modulation for 100G OTU4 line mode, as well as coherent modulation technology. The board also incorporates G.709 FEC and SD-FEC error correction functions to ensure reliable transmission.
