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: available from 0.5m (2ft) to 7m (23ft) in 7 standard options
• 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 supplied 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-4SFP10G-CU1M.

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.

This model carries part number QSFP-40G-4SPC01. You can order this assembly in 0.5m (2ft), 1m (3ft), 2m (7ft), 3m (10ft), 4m (13ft), 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.

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.

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.

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.
