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. Digital diagnostics report transmit power, receive power and temperature in real time, which simplifies commissioning and ongoing maintenance. 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.
Standards and Compatibility
Compliance: IEEE 802.3bm, QSFP-DD MSA Compliant, CMIS 4.0. For projects standardized on Dell hardware, this product replaces the Q28DD-200G-2SR4 directly, with identical fit and function. Every unit's EEPROM coding and link behavior are verified on real host equipment in our lab, so what arrives at your site is ready to use.
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.
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.
Shipping and Lead Time
Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.
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.
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.
