100G QSFP28 to 1x 25G SFP28 Passive DAC

The 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) provides a 25Gbps copper connection between QSFP28 to SFP28 ports with a cable length of 1m (3ft). 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.

Product Highlights

• QSFP28 to SFP28
• Data rate: 25Gbps
• Cable type: Passive Twinax
• Length: available from 1m (3ft) to 5m (16ft) in 4 standard options
• Operating temperature: 0 to 70°C (32 to 158°F)

Designed for 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) carries 25Gbps between QSFP28 to SFP28 interfaces. This unit is supplied in 4 standard lengths from 1m (3ft) to 5m (16ft). The integrated construction removes separate optics from the link budget and reduces the number of failure points in the row. If your project needs a specific vendor coding or custom label, our production line handles it as a routine step before packing.

Standards compliance covers QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. The unit works in any equipment with a standard QSFP28 to SFP28 interface; if your network uses a specific vendor's coding, tell us the switch model and we will program and verify it before delivery.

This model carries part number QSFP-100G-1SPC01. You can order this assembly in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Non-standard lengths can be produced on request. Wire gauge: 26AWG. Samples for testing can be arranged before bulk orders.

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.

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

From incoming component inspection to final burn-in, quality is controlled at each step of production. Finished units are verified on real networking equipment in our compatibility lab, and test records are kept per batch so that any field question can be traced back quickly.

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.
