100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC

For short reach 100Gbps links in 100G Ethernet, data center interconnect and 5G transport networks, the 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) offers a factory terminated passive twinax assembly with QSFP28 to SFP28 connectors and a length of 0.5m (2ft). As a passive cable it draws essentially no power and adds no latency to the link. The cable meets IEEE 802.3, QSFP28 MSA, SFF-8665.

The 100G QSFP28 4x 25G NRZ to 4x 25G SFP28 25G NRZ Passive Breakout DAC, 0.5m (2ft) is a 100Gbps direct attach copper cable for QSFP28 to SFP28 connections in 100G Ethernet, data center interconnect and 5G transport networks. This unit is available in 8 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-4SFP25G-CU50CM directly. The link runs QSFP28-4x 25G-NRZ SFP28-1x 25G-NRZ modulation, which keeps it aligned with current 100G switch silicon.

On the compatibility side, this unit is the practical equivalent of the Cisco part QSFP-4SFP25G-CU50CM and works in Cisco systems out of the box. Standards compliance covers IEEE 802.3, QSFP28 MSA, SFF-8665.

The part number of this assembly varies with length, for example QSFP-100G-4SPC005 for the shortest option. We supply this cable in 0.5m (2ft), 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 3.5m (11ft) and 5m (16ft). Custom lengths beyond this range can also be produced on request. Wire gauge: 30AWG. Volume pricing is available for project quantities.

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.

Standard packing is an anti-static bag plus blister protection, with cartons sized to keep products from moving in transit. We apply our standard labels by default; neutral packing or customer-branded labels, part number stickers and serial barcodes are all available on request.

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.

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.
