800G QSFP112-DD

TNL-0800-DD

The Thenewlink 800G QSFP112-DD delivers 800 Gbps over single-mode fiber using eight 100G PAM4 lanes in the familiar QSFP-DD footprint. It eases migration for operators standardizing on QSFP cages — dropping into existing QSFP-DD slots while offering DR8 and 2×FR4 reach from 500 m to 2 km. It is compliant with 800G Ethernet, IEEE 802.3bs and the QSFP-DD MSA.
