Description

High-density twin-port 800G OSFP optical transceiver using 850nm MMF with two MPO-12 APC interfaces, ideal for building scalable AI/ML and spine–leaf fabrics. Delivers two independent 400G links (aggregate 800G) over short-reach multimode up to 50 m. Flat-top mechanical design for dense thermal envelopes.

Features

- Twin-port OSFP delivers two independent 400G links from a single module
- 2x MPO-12 APC interfaces for high-density parallel MMF connectivity
- Short-reach SR8 optics optimized for low-latency in-rack/row fabrics
- Flat-top mechanical for dense, high-thermal chassis designs
- Ideal for AI/ML clusters, spine–leaf, and NDR/400GbE aggregation
- Host-protocol agnostic optical layer (Ethernet or InfiniBand depending on platform)

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

Technical Specifications

FAQs

Q: Is this OSFP module compatible with QSFP-DD ports?
A: No. OSFP and QSFP-DD are different form factors and are not cross-compatible.

Q: What fiber and connector do I need?
A: Use multimode OM3/OM4 trunk cables terminated with MPO-12 APC connectors. Match polarity and gender to your platform guidance.

Q: Can it be used for both Ethernet and InfiniBand?
A: Yes, the optical layer supports either. Actual protocol operation is determined by the host port and platform configuration.

Q: What does flat-top mean?
A: Flat-top refers to a low-profile mechanical top without fins, aiding thermal/mechanical fit in dense systems.

Q: What is the maximum supported reach?
A: Up to 50 meters as specified for this MMF SR link.
