NTT Electronics Ships Single-Chip 100G OTN Framer

NTT Electronics (NEL) released a 100G Optical Transport Network (OTN) Framer with very low power dissipation. The new OTN Framer can be used alongside NEL's 100G Digital Coherent Signal Processor (DSP) and is capable of operation in multiple modes including 100G Transponder, 10 x 10G Muxponder, and 100G Regenerator.

NEL said its new OTN Framer employs advanced CMOS technology to provide framing solutions, fully compliant with the ITU-T G.709 standard, with low power dissipation in the 10 W to 20 W range depending on the selected mode of operation. It also incorporates high-performance Hard-Decision (HD) FEC within a standard 7% OTN overhead. It supports a unique Enhanced FEC, in addition to the Standard GFEC, to provide the improved net coding gain by more than 3 dB. The OTN Framer achieves ultimate performance of the SD-FEC when operated in conjunction with NEL's flagship 100G DSP.
