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

The 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.

Features

Future-Ready Smooth Upgrade to 800G

The 400G QSFP112 SR4 optical module is based on a streamlined 4x100G PAM4 electrical lane design. Simply replace the module to scale up to an 800G solution (8x100G PAM4—2xQ112), enabling seamless evolution to higher bandwidth.

  • Shorten Deployment Cycles
  • Reduce Upgrade Costs
  • Extend Lifecycle

Multiple Application Combinations with Flexible Options

Supporting multi-type device interconnection, it can be flexibly paired with Q112/QDD port switches as well as server adapters such as ConnectX-7 and BlueField-3, helping you freely configure across different architectures while reducing compatibility concerns and investment risks.

  • QSFP112/QSFP-DD Switches
    Connects to high-speed switches to form a high-bandwidth network backbone.
  • Adapter Card
    Plugs directly into server adapters for maximum data transfer speeds.
  • DPU Card
    Interfaces with DPUs to meet high-throughput, low-latency acceleration demands.

Low BER on par with NVIDIA Originals

During LL FEC (272,257) testing, FS transceivers achieve Pre-FEC BER of -8~-10, and near-zero post-correction, reducing operations and maintenance (O&M) complexity and cost.<br/>
