Applications
The 100G QSFP28 to 1x 25G SFP28 Passive DAC, 1m (3ft) connects QSFP28 to SFP28 ports at 25Gbps in 100G Ethernet, data center interconnect and 5G transport networks. This unit is produced 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. The link runs QSFP28-1x 25G-NRZSFP28-1x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
This product is designed and tested to comply with QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8402, IEEE 802.3bj, IEEE 802.3by. It plugs into any standards-based QSFP28 to SFP28 port, and compatibility coding for specific switch or router brands can be done in our factory before shipment.
Ordering Information
The factory part number is QSFP-100G-1SPC01. This cable is available in 1m (3ft), 2m (7ft), 3m (10ft) and 5m (16ft). Lengths outside the standard range are made to order in our factory. Wire gauge: 26AWG. Samples for testing can be arranged before bulk orders.
How We Pack
Transceivers and cables are individually protected against static and dust, then consolidated into sturdy cartons suitable for international courier shipment. For larger orders we shrink-wrap and strap cartons onto pallets. Tell us your warehouse or retail requirements and we will pack accordingly.
OEM and Custom Orders
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.
Logistics
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.
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.
