40G QSFP+ Passive DAC

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.

Product Highlights

• QSFP+ to QSFP+
• Data rate: 40Gbps
• Length: 7 standard options from 0.5m (2ft) to 7m (23ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for 40G Ethernet data center and enterprise network environments, the 40G QSFP+ Passive DAC, 1m (3ft) carries 40Gbps between QSFP+ to QSFP+ interfaces. This unit is available 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.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-H40G-CU1M and works in Cisco systems out of the box. Standards compliance covers SFF-8436, QSFP+ MSA and IEEE 802.3ba.

The standard part number of this assembly is QSFP-40G-PC01. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

Default packaging is simple and protective: sealed bag, blister tray, export carton. For OEM customers we also offer white-label packing, custom printed boxes and per-unit labeling with your own part numbers, so the goods can go straight into your sales channel.

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

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.
