Applications

In 400G Ethernet data center and cloud network environments, the 400G OSFP SR8 Optical Transceiver delivers 425Gbps transmission over MMF with a reach of 100m@OM4. With its MPO-16/APC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards and Compatibility

Standards compliance covers OSFP MSA, CMIS 4.1, IEEE 802.3cd. The unit works in any equipment with a standard Single-port OSFP IHS/Finned 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

To order, quote OSFP-SR8-400G 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.

OEM and Custom Orders

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.

Logistics

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.

Quality and Testing

Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.

Packing Details

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.
