ITU 25G PON LDPC
Encoder and Decoder
The common transmission convergence (ComTC) layer for Higher Speed Passive Optical Networks is defined as part of the FEC in the ITU-T G.9804.2 Recommendation.
The Creonic ITU 25G PON LDPC Encoder and Decoder support the default LDPC (17280, 14592) coding scheme, as well as the optional LDPC (17152, 14592) scheme. The IP cores are available for ASIC and FPGAs (AMD Xilinx, Intel, Microchip).
