Applications
Built for InfiniBand HDR fabrics, HPC clusters and AI computing networks, this Single-port OSFP RHS/Flat Top module carries 425Gbps (4x106.25Gbps) over SMF up to 500m per link. The MPO-12/APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.
Standards and Compatibility
Standards compliance covers OSFP MSA Rev. 5.0, CMIS Rev. 4.0, IEEE Std 802.3bs-2017, IEEE Std 802.3ck-2022. The unit works in any equipment with a standard Single-port OSFP RHS/Flat Top interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.
Ordering Information
Order this product as OSFP-DR4-400G-FL. 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.
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.
Package
Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
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.
Delivery
Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed forwarder.
