RS QSFP-DD 400G ZR+ is a C-Band optical frequency tunable coherent optical transceiver that combines 7nm coherent DSP ASIC functionality with best-in-class ultra-narrow line-width tunable lasers, high-speed modulators, and high-responsivity coherent receivers. It delivers high performance using 100G DP-QPSK, 200G DP-QPSK, 300G DP-8QAM, and 400G DP-16QAM modulation formats, making it ideal for 100G/200G long-haul and 300G/400G Metro IP-over-DWDM networks without the need for inline chromatic dispersion compensation. The QDD-400G-ZR+ is suitable for 400G Ethernet data center solutions over distances up to 120 km, supporting DCI edge and regional interconnections. It can be deployed in a variety of network topologies, including point-to-point, star, and ring networks.

Refurb Squared is brand of OEM-compatible optical networking products, including SFP, SFP+, QSFP+, QSFP28 and QSFP-DD transceivers, DWDM/CWDM systems, media converters, and DAC/AOC cables. Every module is 100% pre-shipment tested and coded for seamless compatibility with major platforms such as Cisco, Huawei, Juniper, Arista, HPE, Dell, Nokia and Fortinet — backed by a lifetime warranty, fast global delivery, and dedicated technical support for data centers, telecom operators, enterprise networks and system integrators worldwide.
