Applications
Built for 400G Ethernet data center and cloud network environments, this QSFP-DD module carries 425Gbps (4x106.25Gb/s) over SMF up to 500m per link. The MPO-12/APC interface and 1310nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. It is interoperable with Arista platforms and replaces the Arista part QDD-400G-DR4 directly.
Standards and Compatibility
This product is designed and tested to comply with QSFP-DD MSA HW Rev 5.1, QSFP-DD CMIS Rev 5.0, IEEE 802.3bs. It is interoperable with Arista equipment and serves as a direct equivalent to the Arista part number QDD-400G-DR4.
Ordering Information
Our part number for this module is QDD-DR4-400G. 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.
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.
Logistics
Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.
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.
Packaging Options
Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.
