Cisco Compatible 400G QSFP-DD QDD XDR4 Optical Transceiver

Designed for data center interconnect, metro transport and carrier aggregation networks, the Cisco Compatible 400G QSFP-DD QDD XDR4 Optical Transceiver provides 400Gbps throughput in a QSFP-DD form factor. It operates at 1310nm over SMF through a MPO-12/APC connector and supports link lengths up to 2km. The module meets QSFP-DD MSA, CMIS.5.0, IEEE 802.3bs and includes digital diagnostic monitoring for live status readout.

Product Highlights

• QSFP-DD form factor, 400Gbps data rate

• Reach: up to 2km
• Fiber media: SMF
• DDM/DOM: Supported

Built for data center interconnect, metro transport and carrier aggregation networks, this QSFP-DD module carries 400Gbps over SMF up to 2km per link. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Standards compliance covers QSFP-DD MSA, CMIS.5.0, IEEE 802.3bs. The unit works in any equipment with a standard QSFP-DD interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

To order, quote QDD-XDR4-400G 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.

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.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.

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.
