Tested & Proven: Every TenFour Optics part is coded, tested, and verified before shipment — see Tested & Proven.

As a parallel, multi-lane optic, this module anchors high-density spine-leaf fabrics and breakout topologies, aggregating several lanes into a single high-speed port. It is a backbone component of modern data-center and AI-cluster builds, where port density and bandwidth per rack-unit are the limiting factors. It operates 10km in the 1310nm window.

Coded to the host EEPROM, it comes up as a genuine module: full diagnostic visibility, no compatibility warnings, and side-by-side operation with optics already in the chassis.

Before shipment every module is coded to the host platform, then verified for protocol conformity, diagnostic accuracy, and end-face cleanliness. Class 1 laser certified, RoHS compliant.
