The US Transceivers compatible QDD-400G-ZRP-S is a 400GBASE-ZR+ QSFP-DD tunable coherent DCO (Digital Coherent Optics) transceiver engineered for high-capacity long-haul and metro optical networking. Operating across the C-band with a tunable wavelength range of 1528.77 nm to 1568.36 nm (191.35 THz to 196.10 THz), this module supports transmission distances up to 1000 km over single-mode fiber, making it ideal for demanding carrier and data center interconnect deployments.<\/p>\n
Built in the compact QSFP-DD form factor, this transceiver delivers 400G line-side capacity using DP-16QAM modulation and is fully compliant with the OpenZR+ MSA specification. The integrated DSP-based coherent engine enables advanced forward error correction, dispersion compensation, and real-time performance monitoring via DDM\/DOM, eliminating the need for external transponders.<\/p>\n
The US Transceivers compatible QDD-400G-ZRP-S is TAA compliant and RoHS certified, offering a cost-effective, interoperable alternative for service providers, hyperscale operators, and enterprise networks requiring scalable, software-defined optical transport over existing fiber infrastructure.<\/p>\n","protected":false},"excerpt":{"rendered":"
