Supporting up to 40km unamplified and up to 120km with EDFA amplification, it uses DP-16QAM modulation with C-FEC per the OIF-400ZR MSA standard, enabling both 400GbE single-wavelength and 4x100GbE breakout modes across ITU C-Band tunable wavelengths. The integrated coherent DSP eliminates the need for external transponders, dramatically simplifying metro and campus DCI architectures.\u003cbr\u003e\u003cbr\u003eCompliant with OIF-400ZR MSA, QSFP-DD MSA, and IEEE 802.3bs, the QDD-400G-ZR2 delivers multi-vendor interoperability and real-time digital optical monitoring (DOM) for proactive network management. Its full C-Band tunability allows flexible DWDM channel assignment suited to hyperscale and metro edge deployments.
