400G QSFP112 PCxxx Passive DAC

The 400G QSFP112 PCxxx Passive DAC is a passive twinax direct attach copper cable with QSFP 112 to QSFP 112, supporting 400Gbps links over a length of 0.5-1.5m (2ft-5ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 400G Ethernet data center and cloud network environments, and complies with industry MSA standards.

Designed for 400G Ethernet data center and cloud network environments, the 400G QSFP112 PCxxx Passive DAC carries 400Gbps between QSFP 112 to QSFP 112 interfaces. This unit is supplied at 0.5-1.5m (2ft-5ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. It is interoperable with platforms and replaces the part Generic directly.

Compliance: industry MSA standards. For projects standardized on hardware, this product replaces the Generic 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.

This model is supplied at 0.5-1.5m (2ft-5ft) under part number QSFP-400G-PCxxx. Other lengths of the same assembly can be produced on request. Wire gauge: 26~30AWG. Volume pricing is available for project quantities.

Each unit is sealed in an anti-static bag, cushioned in a blister tray and boxed in an export-grade carton. Outer cartons carry handling marks and can be palletized for air or sea freight. If your project requires retail boxes, barcodes or your own brand on the label, we can arrange that as well.

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.

Goods are normally sent by courier such as DHL, UPS, FedEx, TNT or EMS; air and sea freight are also available on request. Commonly used items are kept in stock for immediate shipment, and out-of-stock items are usually delivered within a few working days. We can also ship on your courier account or hand goods to your appointed 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.
