PacketLight's 100G coherent products includes OTN-based muxponders and transponders. The 100G DWDM muxponders support the aggregation of a flexible mix of multi-protocol multi-rate 10/40Gb Ethernet, 8/16/32G Fibre Channel, STM-64 SONET/SDH and OTU2/2e/3 OTN services over a single OTN 100G DWDM uplink. The 100G transponders support the mapping of 100GbE and OTU4 clients into an OTN DWDM coherent uplink.

The high performance 100G coherent solution enables transport of data over long-haul networks and can be used as alien wavelength over existing links. It is an effective solution for building backbone as it supports digital dispersion compensation for thousands of kilometers and utilizes a single wavelength, which simplifies the network, increases spectral efficiency and capacity and reduces the solution cost.

PacketLight's 100G integrated 1U devices provide a simple, cost-effective upgrade to existing infrastructure and offer high throughput and cost-effective transport solutions.

The devices include optional Layer-1 optical encryption, performing GCM-AES-256 encryption on Layer-1 without any degradation to the full bandwidth of GbE/10/40/100Gb Ethernet and 8/16/32G Fibre Channel services. The solution is NIST FIPS 140-2 and Common Criteria EAL2 certified, and complies with Commercial National Security Algorithm (CNSA) Top Secret Suite B 2015 requirements for GbE/10/40/100Gb Ethernet. This enables carriers to offer secured infrastructure to customers that demand high level of confidentiality.

PacketLight’s coherent solution supports a soft decision (SD) FEC layer and embedded digital signal processing for chromatic dispersion tolerance of up to 40,000 ps/n. High spectral efficiency, SD-FEC, and dispersion tolerance have made it easier to reach longer distances with less expenditure on optical infrastructure, and eliminate the need for regenerators along the network, also reducing CAPEX and OPEX.
