Applications

The 800G OSFP DR8L FL Optical Transceiver is used in InfiniBand NDR fabrics, GPU clusters and AI training networks, where it provides an 850Gbps (8x 106.25Gbps) link over SMF up to 100m. The Dual MTP/MPO-12 APC interface and 1310nm 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 PAM4 modulation, which keeps it aligned with current 800G switch silicon.

Standards and Compatibility

Compliance: IEE802.3ck, IEEE 802.3cu, OSFP MSA. 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

Our part number for this module is OSFP-DR8L-800G-FL. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

Shipping and Lead Time

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Our Testing Process

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.

How We Pack

Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.

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.
