Applications
Network architects choose the 200G QSFP-DD QDD SR4 2x100G Optical Transceiver for 200G Ethernet data center and cloud network environments: it runs 206.24Gbps(8x 25.78Gbps) over MMF and reaches 100m. With its MPO-24/UPC optical interface, the module works directly with the MMF infrastructure already installed in most facilities. Compatibility with Dell systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of Q28DD-200G-2SR4. The link runs 8x25G-NRZ modulation, which keeps it aligned with current 200G switch silicon.
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
Order this product as QDD-SR4-2X100G. Common models are stocked for fast dispatch. We can supply the module with neutral or customer-branded labels, and compatibility coding for a specific equipment vendor can be added at no extra process step.
Our Testing Process
Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.
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.
Factory Custom Capability
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.
How We Ship
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.
