Credo demos single-lane 50G NRZ in support of 400G CWDM8 MSA to enable deployment of 400G 2km and 10km optical links in data centers
In Keysight’s booth (Hall 3, stand 239) at the European Conference on Optical Communications (ECOC 2017) in Gothenburg, Sweden (18-20 September), Credo Semiconductor of Milpitas, CA, USA, which provides serializer-deserializer (SerDes) mixed-signal semiconductor technology for data-center, enterprise networking and high-performance computing applications, is demonstrating single-lane 50G NRZ (non-return-to-zero) transmission.
A device supporting CDR (clock & data recovery) functionality for 50G PAM4 host-side electrical facing interfaces to 50G NRZ optical line-side facing interfaces is a key enabling building block for optical modules conforming to the CWDM8 MSA (8-wavelength coarse wavelength division multiplexing multi-source agreement), says Credo.
Working with Keysight, Credo is showing a live demo of its low-power 50G PAM4 to 50G NRZ technology in support of the CWDM8 MSA’s effort to accelerate 400G optical module deployments.
