400G OSFP DR4+
TNL-0400-DR4P
The Thenewlink 400G OSFP DR4+ is a hot-pluggable optical transceiver that delivers 400 Gbps over single-mode fiber using four 100G PAM4 lanes. Built on a 1310 nm EML transmitter with an MPO-12 interface, the DR4+ variant extends reach to 2 km while holding power under 10 W. It is compliant with the OSFP MSA, IEEE 802.3bs and the 100G Lambda MSA.
