Optical transport media reaching their limits are facing the same channel impairments and signal degradation. To overcome these limits, we’ve developed and implemented waveforms including higher-order modulation schemes, and advanced FECs. FEC technologies include Turbo Product Code (TPC), Low Density Parity Check (LDPC) and Bose Chaudhuri Hocquenghem (BCH). Our products include IP cores for FPGAs and ASICs.
- Our soft and hard decision FECs exceed the performance requirements defined by the ITU-T G.709 and G.975 submarine standards for ultra-long haul (ULH) links.
- Product Offering (ASIC 45/65 nm/ FPGA net list )
