Description

QSFP+ optical module optimized for fabric-extender uplinks, using parallel 4x10G lanes at 850nm over multimode fiber. Offers short-reach MMF connectivity with MPO-12 interface; intended for platform-supported FEX-to-parent links rather than general 40GBASE-SR4 interoperability. Verify platform software and optics policy for FET compatibility.

Features

- Short-reach 40G MMF link for fabric-extender uplinks
- QSFP+ form factor with MPO-12 interface
- 850 nm parallel optics; 100 m OM3 / 150 m OM4 reach
- Platform-validated FET coding for reliable operation
