The ECPO-QDDZR400G is a 400 Gbps tunable dense wavelength division multiplexing (DWDM) DP-16QAM coherent transceiver. ZR+, Standard Tx output power (-10dBm), C-band tunable, Pull tab, 0°C to 70°C, LC receptacle The emerging OIF 400ZR and Open ZR+ MSA coherent transceivers in QSFP-DD and OSFP form factors generally have low transmit output power (-10 dBm), making them incompatible with ROADM networks. Consequently. Cisco offers a comprehensive range of pluggable optical modules in the Cisco ® pluggables portfolio. The wide variety of modules gives you flexible and cost-effective options for all types of interfaces. Cisco offers a range of GBIC, SFP, XFP, SFP+, CXP, CFP, Cisco CPAK, and QSFP+ pluggable. The 400G QSFP-DD ZR+ is a C-Band optical frequency tunable coherent optical module, that combines 7nm coherent DSP ASIC functionality with best-in-class ultra-narrow line-width tunable lasers, high-speed modulators and high responsively coherent receivers. This transceiver is also the one capable. y coherent detection, and advanced electronic link equalization. Chromatic dispersion comp nsation can be applied to the receiving side of the demodulator. This module is managed to utilize the Two Wire Interface that is s ide are provided through the optical receptacles on the QSFP-DD. The module. QSFP-DD (Quad Small Form-Factor Pluggable Double Density) represents a transformative advancement in optical transceiver technology, addressing the exponential growth in data center bandwidth requirements and the demands of modern high-performance computing environments. As data traffic continues. NADDOD introduces a new range of 400G Digital Coherent QSFP-DD transceivers with three variants: ZR (QDD-400G-ZR) for 400G 120Km DCI DWDM applications, ZR Plus (QDD-400G-ZR+) for 100G/200G long haul and 300G/400G Metro IP over DWDM, and ZR+ Pro/High Power (QDD-400G-ZRP+) is an enhanced version of.
