40G QSFP+ to 4 x 10G SFP+ Passive Breakout DAC

The 40G QSFP+ to 4 x 10G SFP+ Passive Breakout DAC, 1m (3ft) provides a 40Gbps copper connection between QSFP+ to 4 SFP+ ports with a cable length of 1m (3.28ft). As a passive cable it draws essentially no power and adds no latency to the link. Direct attach copper keeps both latency and power consumption to a minimum, which makes it the economical choice for 40G Ethernet data center and enterprise network environments.

Product Highlights

• QSFP+ to 4 SFP+
• Data rate: 40Gbps
• Length: 7 standard options from 0.5m (2ft) to 7m (23ft)
• Operating temperature: 0 to 70°C (32 to 158°F)

In 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 4 x 10G SFP+ Passive Breakout DAC, 1m (3ft) provides a factory terminated 40Gbps link between QSFP+ to 4 SFP+ ports. This unit is available in 7 standard lengths from 0.5m (2ft) to 7m (23ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-4SFP10G-CU1M directly.

Compliance: SFF-8436, SFF-8431 and QSFP+ MSA. For projects standardized on Cisco hardware, this product replaces the QSFP-4SFP10G-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.

The standard part number of this assembly is QSFP-40G-4SPC01. We supply this cable in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft), 5m (16ft) and 7m (23ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG.

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.

Our warehouse keeps fast-moving transceivers and cables ready for same-week dispatch. Courier, air freight and sea freight options are all available depending on your budget and schedule, and we consolidate multiple items into one shipment whenever it saves you cost.

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.
