Credo demos single-lane 100G PAM-4 for hyper-scale data-center connectivity in 100G, 200G and 400G networks

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 mixed-signal semiconductor technology for data-center, enterprise networking and high-performance computing applictions, is demonstrating single-lane 100G PAM-4 (4-level pulse amplitude modulation) serializer-deserializer (SerDes) performance.

Hyper-scale data-center providers view 100G-per-lambda optical connectivity as a strategic priority, says Credo. The demonstration hosted in the Keysight booth shows the complete transmit path from two 50G PAM-4 host-side interface lanes to a single-lane 100G PAM-4 optical Tx. Implementations that can be supported with this technology include 400G-DR4/FR4 in addition to 100G-DR/FR/LR.
