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

A short single-mode optic built for intra-data-center reach, a common breakout endpoint in 100G and 400G leaf-spine designs. It lets a structured-cabling shop standardize on one fiber type end to end while still covering hall-to-hall distance. It operates 500m in the 1310nm window.

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.

We program each module to the Juniper host EEPROM and run it through traffic, DOM, and optical-cleanliness checks before it ships. Class 1 laser certified and RoHS compliant.
