400G OSFP SR8 Optical Transceiver

Designed for 400G Ethernet data center and cloud network environments, the 400G OSFP SR8 Optical Transceiver provides 425Gbps throughput in a Single-port OSFP IHS/Finned Top form factor. It operates at 850nm over MMF through a MPO-16/APC connector and supports link lengths up to 100m@OM4. The module meets OSFP MSA, CMIS 4.1, IEEE 802.3cd and includes digital diagnostic monitoring for live status readout.

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. The MPO-16/APC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OSFP MSA, CMIS 4.1, IEEE 802.3cd. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
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.
Packaging
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.
Built to Your Spec
Our product line has grown with the industry for three decades, from GBIC-era modules to today's 800G and 1.6T interconnects. If the exact configuration you need is not listed, we can usually build it: custom lengths, mixed connector breakouts, OEM branding and project-specific firmware coding are all supported.
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.
