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: available from 0.5m (2ft) to 7m (23ft) in 7 standard options
• Operating temperature: 0 to 70°C (32 to 158°F)

The 40G QSFP+ Passive DAC, 1m (3ft) is a 40Gbps direct attach copper cable for QSFP+ to QSFP+ connections in 40G Ethernet data center and enterprise network environments. This unit is supplied in 7 standard lengths from 0.5m (2ft) to 7m (23ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-H40G-CU1M.

Compliance: SFF-8436, QSFP+ MSA and IEEE 802.3ba. For projects standardized on Cisco hardware, this product replaces the QSFP-H40G-CU1M 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 carries part number QSFP-40G-PC01. You can order this assembly in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 3m (10ft), 5m (16ft) and 7m (23ft). Non-standard lengths can be produced on request. Wire gauge: 30AWG.

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.

Production samples and every outgoing batch pass through bit-error-rate measurement, temperature verification and plug-in compatibility checks on mainstream switches and routers. Because we are the manufacturer, any issue found in testing is fed back to the production line immediately instead of being passed on to customers.

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.

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.
