The 200G QSFP-DD QDD SR4 2x100G Optical Transceiver is used in 200G Ethernet data center and cloud network environments, where it provides a 206.24Gbps(8x 25.78Gbps) link over MMF up to 100m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. It is interoperable with Dell platforms and replaces the Dell part Q28DD-200G-2SR4 directly.

On the compatibility side, this unit is the practical equivalent of the Dell part Q28DD-200G-2SR4 and works in Dell systems out of the box. Standards compliance covers IEEE 802.3bm, QSFP-DD MSA Compliant, CMIS 4.0.

Our part number for this module is QDD-SR4-2X100G. 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.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

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.
