100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft)
The 100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft) is a passive twinax direct attach copper cable with QSFP28 to QSFP28, supporting 100Gbps links over a length of 0.5m (1.64ft). As a passive cable it draws essentially no power and adds no latency to the link. It is a cost effective, low latency interconnect for 100G Ethernet, data center interconnect and 5G transport networks, and complies with QSFP28 MSA, SFF-8662, IEEE 802.3.

Applications
In 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft) provides a factory terminated 100Gbps link between QSFP28 to QSFP28 ports. This unit is delivered in 7 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. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-CU0.5M directly. The link runs 4x 25G-NRZ to 4x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.
Standards and Compatibility
Compliance: QSFP28 MSA, SFF-8662, IEEE 802.3. For projects standardized on Cisco hardware, this product replaces the QSFP-100G-CU0.5M 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
Part numbers change with length, for example QSFP-100G-PC005 at the shortest length. We make this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft) and 5m (16ft). Special lengths outside this range can be produced to order. Wire gauge: 30AWG.
Tested Before Shipment
We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.
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.
Custom-made Fiber Products
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.
How We Ship
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.
