200G QSFP56 SR4 Optical Transceiver

The 200G QSFP56 SR4 Optical Transceiver is a hot-pluggable QSFP56 transceiver rated at 200Gbps. Using a MPO-12/UPC optical interface over MMF at 850nm, it covers transmission distances up to 70m@OM3/100m@OM4. Compliance with IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8636, together with integrated diagnostic monitoring, makes it a dependable choice for InfiniBand HDR fabrics, HPC clusters and AI computing networks.

Applications
The 200G QSFP56 SR4 Optical Transceiver is used in InfiniBand HDR fabrics, HPC clusters and AI computing networks, where it provides a 200Gbps link over MMF up to 70m@OM3/100m@OM4. The MPO-12/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with NVIDIA/Mellanox Ethernet systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of MMA1T00-VS. The link runs 4x50G-PAM4 modulation, which keeps it aligned with current 200G switch silicon.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the NVIDIA/Mellanox Ethernet part MMA1T00-VS and works in NVIDIA/Mellanox Ethernet systems out of the box. Standards compliance covers IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8636.
Ordering Information
Our part number for this module is QSFP-SR4-200G. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
