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

For short reach 40Gbps links in 40G Ethernet data center and enterprise network environments, the 40G QSFP+ to 4 x 10G SFP+ Passive Breakout DAC, 1m (3ft) offers a factory terminated twinax assembly with QSFP+ to 4 SFP+ connectors and a length of 1m (3.28ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets SFF-8436, SFF-8431 and QSFP+ MSA.

Product Highlights

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

The 40G QSFP+ to 4 x 10G SFP+ Passive Breakout DAC, 1m (3ft) is a 40Gbps direct attach copper cable for QSFP+ to 4 SFP+ connections in 40G Ethernet data center and enterprise network environments. This unit is provided 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. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-4SFP10G-CU1M.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-4SFP10G-CU1M and works in Cisco systems out of the box. Standards compliance covers SFF-8436, SFF-8431 and QSFP+ MSA.

This assembly is listed under part number QSFP-40G-4SPC01. The cable is supplied in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft), 5m (16ft) and 7m (23ft). Custom lengths beyond the standard range are available on request. Wire gauge: 30AWG.

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.

Most orders travel by international express and arrive within days; palletized freight by air or sea is used for volume orders. If you prefer, we ship on your DHL, UPS or FedEx account, or deliver to your appointed agent in China for onward consolidation.

Before any product leaves our factory it goes through optical performance testing, compatibility verification on real switch platforms and a final visual inspection. Our in-house test lab holds a wide range of current and legacy switches from major brands, so interoperability is proven on the actual equipment your network uses rather than assumed from paper specifications.

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.
