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

A medium-reach single-mode module tuned for the modern data center — short interconnect hops between halls and rows in high-density spine-leaf fabrics. It pairs single-mode reach with low latency and modest power for 100G-and-up east-west traffic that has outgrown multimode. It operates 2km in the 1310nm window.

Coded to the host EEPROM, it provides full diagnostic visibility.

We program each module to the Juniper host EEPROM and run it through traffic, DOM, and optical-cleanliness checks before it ships. Compliance documentation (RoHS declaration, IEC 60825-1 laser classification) is available on request for project quotes.
