Applications
In 400G Ethernet data center and cloud network environments, the Cisco Compatible 400G QSFP-DD QDD DR4 Si Optical Transceiver delivers 425Gbps (4x106.25Gb/s) transmission over SMF with a reach of 500m. With its MPO-12 (APC) optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part QDD-400G-DR4-S directly.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA, IEEE 802.3bs, CMIS 4.1. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QDD-400G-DR4-S.
Ordering Information
Our part number for this module is QDD-DR4-400G-SI. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.
Package
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.
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.
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.
Reliability Control
From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.
