AscentOptics’ 400G QSFP112 optical transceivers are compliant with the QSFP112 MSA and CMIS 4.0.it support 4 lane of 112G-PAM4 electrical signals and 4 lane of 112G optical signals. QSFP112 is backward compatible with the current QSFP 40G(4x10G), 100G(4x25G) and 200G(4x56G-PAM4) modules. We offer 400G QSFP112 optical transceivers, including DR4 500M and FR1 2km with 1310nm wavalenth, and FR4 2km and LR4 10km with CWDM4 wavelenth. QSFP112 will be the most convenient and best cost-effective way to upgrade the intra data center network bandwidth from 200G to 400G while keep the same network architecture.
