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
Designed for 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 4x 25G NRZ Passive DAC, 0.5m (2ft) carries 100Gbps between QSFP28 to QSFP28 interfaces. This unit is made 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. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of QSFP-100G-CU0.5M. The link runs 4x 25G-NRZ to 4x 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, SFF-8662, IEEE 802.3. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number QSFP-100G-CU0.5M.
Ordering Information
Part numbers differ by length, for example QSFP-100G-PC005 at the shortest length. We offer this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft) and 5m (16ft). Other lengths can be custom manufactured on request. Wire gauge: 30AWG.
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.
Customization Service
Because we are the factory, customization is straightforward: non-standard lengths, different jacket materials, specific polarity or breakout wiring, and compatibility programming for particular switch brands are all routine work for us. Small trial orders are accepted so you can verify quality before scaling up.
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.
Quality and Testing
Every unit we ship is tested in our own test bed on mainstream switch and transport platforms before packing. Our test center has been fully upgraded, which sets us apart from other third party product providers: 10G, 40G, 100G, 200G and 400G transceivers and direct attach cables are verified on the latest top brand equipment, including selected original switches that can hardly be found elsewhere.
