The ECPO-QDDZR400G is a 400 Gbps tunable dense wavelength division multiplexing (DWDM) DP-16QAM coherent transceiver. • 400ZR is an interoperable, cost-effective, 400Gb/s interface based on single-carrier coherent DP-16QAM modulation, low power DSP supporting absolute (Non-Differential) phase encoding/decoding, and a Concatenated FEC (C-FEC) with a post-FEC error floor <1. What. High-Speed Interconnects: Backend network requires high speed 100G/200G or 800G optics to connect servers and network switches. These high bandwidth connections are essential for handling the data generated by AI workloads Switch ports deployed in the front-end connectivity with Ethernet to grow. Market Forecast By Form Factor (QSFP, QSFP+, QSFP-DD, and QSFP28, SFP+ and SFP28, SFF and SFP, CFP, CFP2, and CFP4, CXP, XFP), By Application (Telecommunication (Ultra-long-haul Network, Long-haul Network, Metro Network), Data Center (Data Center Interconnect, Intra-Data Center Connection). Majority of the switch ports in AI back-end Networks to be 800 Gbps in 2025 and 1600 Gbps in 2027, showing a very fast migration to the highest speeds available in the market. These challenges are forcing innovation to happen at all levels, including pluggable modules. But pluggable modules still. The Optical Line System (OLS) 400G is a modular optical transmission system that maximizes fiber capacity.
