Applications
Built for data center interconnect, metro transport and carrier aggregation networks, this QSFP-DD module carries 400Gbps over SMF up to Amplified: ≤120km Unamplified: ≤40km per link. The Duplex LC/UPC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Juniper systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QDD-400G-ZR.
Standards and Compatibility
This product is designed and tested to comply with OIF 400ZR, OIF-CMIS-05.2, OIF-C-CMIS-01.2, QSFP-DD-Hardware-Rev6.3, IEEE Std 802.3-2018. It is interoperable with Juniper equipment and serves as a direct equivalent to the Juniper part number QDD-400G-ZR.
Ordering Information
Order this product as QDD-ZR-400G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
Factory Custom Capability
Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.
Worldwide Delivery
We ship to customers around the world every week. Express couriers handle most orders door to door in a few days; larger consignments go by air or sea to keep freight costs down. Tracking information is provided for every shipment, and we are flexible on shipping accounts and forwarders.
