Applications
In 200G Ethernet data center and cloud network environments, the 200G QSFP-DD QDD SR4 2x100G Optical Transceiver delivers 206.24Gbps(8x 25.78Gbps) transmission over MMF with a reach of 100m. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. For networks standardized on Dell hardware, it is a drop-in equivalent of the 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.
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
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.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
