40G QSFP+ Passive DAC, 1m (3ft)
The 40G QSFP+ Passive DAC, 1m (3ft) is a twinax direct attach copper cable with QSFP+ to QSFP+, supporting 40Gbps links over a length of 1m (3.28ft). 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 40G Ethernet data center and enterprise network environments, and complies with SFF-8436, QSFP+ MSA and IEEE 802.3ba.

Applications
The 40G QSFP+ Passive DAC, 1m (3ft) connects QSFP+ to QSFP+ ports at 40Gbps in 40G Ethernet data center and enterprise network environments. This unit is made in 7 standard lengths from 0.5m (2ft) to 7m (23ft). Because the assembly is factory terminated and tested as a complete link, installation is plug and play on both ends. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-H40G-CU1M.
Standards and Compatibility
This product is designed and tested to comply with SFF-8436, QSFP+ MSA and IEEE 802.3ba. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-H40G-CU1M.
Ordering Information
The part number for this assembly is QSFP-40G-PC01. We offer this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Other lengths can be custom manufactured on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.
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.
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.
