200G QSFP56 SL4 Optical Transceiver

Designed for InfiniBand HDR fabrics, HPC clusters and AI computing networks, the 200G QSFP56 SL4 Optical Transceiver provides 200Gbps throughput in a QSFP56 form factor. It operates at 850nm over MMF through a MPO-12/UPC connector and supports link lengths up to 30m. The module meets IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8636 and includes digital diagnostic monitoring for live status readout.

Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this QSFP56 module carries 200Gbps over MMF up to 30m per link. With its MPO-12/UPC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment. The link runs 4x50G-PAM4 modulation, which keeps it aligned with current 200G switch silicon.

Standards compliance covers IEEE 802.3bs, QSFP56 MSA, SFF-8665, SFF-8636. The unit works in any equipment with a standard QSFP56 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

To order, quote QSFP-SL4-200G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.
