400G QSFP112 XDR4 Optical Transceiver

Designed for InfiniBand HDR fabrics, HPC clusters and AI computing networks, the 400G QSFP112 XDR4 Optical Transceiver provides 425Gbps (4x106.25Gb/s) throughput in a QSFP112 form factor. It operates at 1310nm over SMF through a MPO-12/APC connector and supports link lengths up to 2km. The module meets QSFP-112 MSA, CMIS Rev 5.2, IEEE 802.3bs, OIF-CEI-112G-VSR-PAM4 and includes digital diagnostic monitoring for live status readout.

Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this QSFP112 module carries 425Gbps (4x106.25Gb/s) over SMF up to 2km per link. With its MPO-12/APC optical interface, the module works directly with the SMF 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.

Standards compliance covers QSFP-112 MSA, CMIS Rev 5.2, IEEE 802.3bs, OIF-CEI-112G-VSR-PAM4. The unit works in any equipment with a standard QSFP112 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

Order this product as QSFP112-XDR4-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

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.

Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
