100G QSFP28 4x 25G NRZ to 2x 50G QSFP28 2x 25G NRZ Passive Breakout DAC, 0.5m (2ft)

The 100G QSFP28 4x 25G NRZ to 2x 50G QSFP28 2x 25G NRZ Passive Breakout DAC, 0.5m (2ft) is a passive breakout dac direct attach copper cable with QSFP28 to 2x SFP28, supporting 100Gbps links over a length of 0.5m (2ft). 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 IEEE 802.3, QSFP28 MSA, SFP-8665, SFF-8636.

The 100G QSFP28 4x 25G NRZ to 2x 50G QSFP28 2x 25G NRZ Passive Breakout DAC, 0.5m (2ft) connects QSFP28 to 2x SFP28 ports at 100Gbps in 100G Ethernet, data center interconnect and 5G transport networks. This unit is available in 2 standard lengths from 0.5m (2ft) to 3m (10ft). It installs directly into standard ports with no separate transceivers or patch cords to manage at either end. Custom labeling, packaging and compatibility coding for specific equipment vendors are available from our factory on request. The link runs QSFP28-4x 25G-NRZ SFP28-2x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

Compliance: IEEE 802.3, QSFP28 MSA, SFP-8665, SFF-8636. 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.

The part number of this assembly varies with length, for example QSFP-100G-2QPC005 for the shortest option. We supply this cable in 0.5m (2ft) and 3m (10ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Samples for testing can be arranged before bulk orders.

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.

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.

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.

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.
