Cisco Compatible 400G QSFP-DD QDD XDR4 Optical Transceiver

The Cisco Compatible 400G QSFP-DD QDD XDR4 Optical Transceiver is a hot-pluggable QSFP-DD transceiver rated at 400Gbps. Using a MPO-12/APC optical interface over SMF at 1310nm, it covers transmission distances up to 2km. Compliance with QSFP-DD MSA, CMIS.5.0, IEEE 802.3bs, together with integrated diagnostic monitoring, makes it a dependable choice for data center interconnect, metro transport and carrier aggregation networks.

Product Highlights

• QSFP-DD form factor, 400Gbps data rate
• Wavelength: 1310nm
• Connector: MPO-12/APC
• Reach: up to 2km

In data center interconnect, metro transport and carrier aggregation networks, the Cisco Compatible 400G QSFP-DD QDD XDR4 Optical Transceiver delivers 400Gbps transmission over SMF with a reach of 2km. With its MPO-12/APC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs 8x50G-PAM4 modulation, which keeps it aligned with current 400G switch silicon.

Compliance: QSFP-DD MSA, CMIS.5.0, IEEE 802.3bs. 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.

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.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

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.

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
