400G QSFP-DD QDD AC Active DAC Cable

The 400G QSFP-DD QDD AC Active DAC Cable, 5m provides a 425Gbps copper connection between QSFP-DD ports with a cable length of 5m (16ft). Active electronics inside the connectors extend the usable reach compared with passive copper while keeping power draw low. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 400G Ethernet data center and cloud network environments.

The 400G QSFP-DD QDD AC Active DAC Cable, 5m connects QSFP-DD ports at 425Gbps in 400G Ethernet data center and cloud network environments. This unit is available in 4 standard lengths from 1m (3ft) to 5m (16ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. Our factory programs the compatibility coding for your switch brand before shipment and verifies each unit on real host equipment.

Compliance: QSFP-DD MSA, SFF-8636. 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.

The standard part number of this assembly is QDD-400G-AC. We supply this cable in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 28AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.

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.
