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

Short-reach multimode optics like this one live inside the data center — server-to-leaf, leaf-to-spine, and in-row links over OM3 and OM4 fiber where cost-per-port matters more than distance. It is the high-volume workhorse of east-west fabric, keeping optics cost and power low across thousands of ports in a modern build. It operates 100m.

It is programmed to present native host values, so it interoperates link-to-link with OEM modules on the far end and coexists with installed optics in the same line card without compatibility flags.

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.
