Featured with 22.5W low-power, high-density and high-speed, the QSFP-DD transceiver offers a popular way to help you quickly ramp up to 400G transmission.
The transceiver is featured with high-density and mature technology and saves cost with ≤22.5W low power consumption while ensuring first-class product quality.
The 400G ZR+ Pro module allows transmission with the Mux/Demux and EDFA in point-to-point topology up to a distance of 120 km, providing greater scale and higher transfer rates for DCI.
Basing on the OIF 400G-ZR specification, OpenZR+ incorporates parts of the OpenROADM (OFEC) standards to enable more flexible line-side modulation and rate selection, as well as client-side rate adaptation and multiplexing—delivering greater economies of scale for your network.
Reconfiguring the transceiver to work with different brands, <a href="/de-en/products/156801.html" >FS BOX</a> offers flexibility in stock costs.
