100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC

100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC

The 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) provides a 100Gbps copper connection between QSFP28 to SFP28 ports with a cable length of 0.5m (2ft). 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 100G Ethernet, data center interconnect and 5G transport networks.

Applications

The 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) connects QSFP28 to SFP28 ports at 100Gbps in 100G Ethernet, data center interconnect and 5G transport networks. This unit is manufactured in 8 standard lengths from 0.5m (2ft) to 5m (16ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. For networks standardized on Cisco hardware, it is a drop-in equivalent of the QSFP-4SFP25G-CU50CM.

Standards and Compatibility

Compliance: IEEE 802.3, QSFP28 MSA, SFF-8665. For projects standardized on Cisco hardware, this product replaces the QSFP-4SFP25G-CU50CM 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.

Ordering Information

The part number is length dependent, such as QSFP-100G-4SPC005 for the shortest option. Length options are 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 3.5m (11ft) and 5m (16ft). Our factory also produces custom lengths beyond these on request. Wire gauge: 30AWG.

Packaging

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.

Factory Custom Capability

Working directly with the manufacturer means no middleman limits. We support OEM and ODM projects, custom cable assemblies, alternative packaging and compatibility coding for major equipment vendors, with engineering support from the same team that designs our standard products.

Delivery

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.

Our Testing Process

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.
