Infinera’s new Advanced Coherent Toolkit enables operators to improve their fiber capacity-reach performance with Nyquist subcarriers, SD-FEC gain sharing, matrix-enhanced phase shift keying (ME-PSK) modulation and other techniques. The toolkit is enabled by the Infinera optical engine, which combines large-scale photonic integrated circuits (PICs) and FlexCoherent™ Processor ASICs, two key technologies that enable 500 Gb/s and Terabit super-channel transmission and help operators scale intelligent transport networks.
