Generic Compatible 400GBASE-SR4 QSFP112 PAM4 Optical Transceiver Module (MMF, 850nm, 50m, MPO-12/APC, DOM)

The Cisco compatible QSFP112 optical transceiver is an 400Gb/s single-port QSFP112, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The short reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fibre reach of 50-metres using OM4 multi-mode fibres.
The QSFP112 transceiver can be used in QSFP112/QDD switches as well as in ethernet adapters. Featured with low latency, low power, and reliability, it can link upward in spine-leaf architectures to 800G Ethernet switches. It can also interconnect with 400G QSFP-DD or OSFP SR4 to meet diverse application scenarios. When connected to a 1:2 splitter fibre cable, there are only 2 channels on the split end and only 2-channels in the 400G transceiver will be activated, automatically producing 200G speeds and reducing power.
It is an ideal solution for supercomputing, seamlessly integrating into computing and storage infrastructure to ensure efficient high-performance interconnection.
