400G QSFP-DD QDD ZR Optical Transceiver
Designed for data center interconnect, metro transport and carrier aggregation networks, the 400G QSFP-DD QDD ZR Optical Transceiver provides 400Gbps throughput in a QSFP-DD form factor. It operates at its rated wavelength over SMF through a Duplex LC/UPC connector and supports link lengths up to Amplified: ≤120km Unamplified: ≤40km. The module meets OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018 and includes digital diagnostic monitoring for live status readout.

Applications
The 400G QSFP-DD QDD ZR Optical Transceiver is used in data center interconnect, metro transport and carrier aggregation networks, where it provides a 400Gbps link over SMF up to Amplified: ≤120km Unamplified: ≤40km. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Juniper platforms and replaces the Juniper part QDD-400G-ZR directly. The link runs DP-16QAM modulation, which keeps it aligned with current 400G switch silicon.
Standards and Compatibility
Compliance: OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018. For projects standardized on Juniper hardware, this product replaces the QDD-400G-ZR directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
Ordering Information
To order, quote QDD-ZR-400G together with your quantity. Stock items ship quickly; for OEM orders we support custom labels, retail packing and vendor-specific coding, all handled in our own factory.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
Custom-made Fiber Products
As a manufacturer serving the fiber optic industry since 1995, we have strong in-house manufacturing and design capability. From early GBIC, Xenpak and X2 modules to today's SFP, SFP+, QSFP, QSFP-DD and OSFP products, we grow together with the industry. OEM and custom-designed transceivers and cables are welcome, and our factory-direct pricing is very competitive compared with online retail stores.
How We Ship
Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.
