Applications
Built for 200G Ethernet data center and cloud network environments, this QSFP-DD module carries 206.24Gbps(8x 25.78Gbps) over MMF up to 100m per link. With its MPO-24/UPC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. For networks standardized on Dell hardware, it is a drop-in equivalent of the Q28DD-200G-2SR4.
Standards and Compatibility
This product is designed and tested to comply with IEEE 802.3bm, QSFP-DD MSA Compliant, CMIS 4.0. It is interoperable with Dell equipment and serves as a direct equivalent to the Dell part number Q28DD-200G-2SR4.
Ordering Information
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.
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.
Packing Details
Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all 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.
