As service providers modernize aging 10G DWDM infrastructure, AddOn's QSFP28 100G DCO portfolio continues expanding with CTEMP, ITEMP, AutoTune, High Tx, and CMIS-managed options. Designed for legacy QSFP28 switch ports, these transceivers support up to 80km reach while enabling faster deployment, broader compatibility, and cost-effective 100G upgrades.
New ITEMP CMIS variants add management capabilities for simpler provisioning and improved network visibility while maintaining interoperability with existing environments.

Whether you choose our CTEMP, ITEMP, or SFF-8636 options, AddOn provides immediate, multi-vendor interoperability at a lower cost than proprietary OEM solutions.
