Shenzhen, China, July 8, 2021 − Under the context of 5G network, faster broadband speed, longer transmission distance and lower cost are the directions that data center and metro optical transmission network users heading up to. In order to meet market demand, GIGALIGHT recently released the industry's first 200G QSFP56 ER4 optical transceiver. It adopts the mainstream 4-lane WDM optical engine architecture which integrates 4-channel refrigerated EML lasers and APD optical detectors, supports 200GE (4X53 Gbps) and OTN protocols, can perfectly adapt to 200G metro DCI long reach interconnection and 5G backhaul.
