Description
The AddOn Juniper Networks® QDD400GBDCOZRP4DBM-J-ST01-AO is a high-performance, TAA-compliant 400GBase-Open ZR+ coherent QSFP-DD optical transceiver designed for long-haul, high-capacity data center interconnect and metro optical networking applications. Supporting flexible data rates of 400/300/200/100Gbps and distances up to 120 km over single-mode fiber (SMF) — or up to 2000 km with amplification — this hot-swappable module features a tunable C-band transmitter, coherent receivers, and a maximum transmit power of +4 dBm.
With support for both CFEC and oFEC, this transceiver ensures enhanced forward error correction and reliable long-distance transmission. Digital Optical Monitoring (DOM) allows real-time visibility into key operating parameters, while the tunable wavelength and power functions deliver flexibility for dense wavelength-division multiplexing (DWDM) applications. Fully tested for interoperability and performance, this module is guaranteed 100% compatible with Juniper Networks® platforms, delivering robust and scalable optical networking performance with low power dissipation and exceptional reliability.
