400G QSFP112
TNL-0400-112
The Thenewlink 400G QSFP112 is a compact, hot-pluggable optical transceiver that delivers 400 Gbps over single-mode fiber using four 100G PAM4 lanes. Built for leaf and access tiers, it pairs a small thermal envelope and low power draw with DR4, FR4 and LR4 reach options from 500 m to 10 km. It is compliant with 400G Ethernet, IEEE 802.3cu and the QSFP112 MSA.
