What connector configuration does Q100-4S25-C use to divide a 100G QSFP28 port into four 25G links?

It provides one 100G QSFP28 main connector and four 25G SFP28 branch connectors. The four lanes from the QSFP28 side are presented as four separate 25Gb/s Ethernet links at the SFP28 ends.

Can Q100-4S25-C connect one 100G switch port directly to four network devices equipped with 25G SFP28 ports?

Yes. The QSFP28 connector plugs into the compatible 100G host port, while the four SFP28 connectors attach to four separate 25G ports. The host QSFP28 port must support 4×25G breakout operation.

Which cable lengths are available for the Q100-4S25-C passive copper breakout cable?

0.5m to 5m. These lengths are intended for short-distance copper connections within equipment racks or between closely located network devices.

Does Q100-4S25-C require separate optical transceivers, fiber jumpers, or an external power source?

No. Q100-4S25-C is an integrated passive direct attach copper assembly, so separate optical modules and fiber jumpers are not required. Its passive design also operates without an additional external power source.

Which interface and Ethernet specifications does the Q100-4S25-C breakout DAC comply with?

It complies with IEEE 802.3bj, SFF-8665, and SFF-8402. These specifications cover the relevant 100G Ethernet electrical operation and the QSFP28 and SFP28 pluggable interface requirements used by the cable.

What information should be provided when checking Q100-4S25-C compatibility before ordering?

Provide the 100G QSFP28 host model, the four 25G SFP28 endpoint models, the required 4×25G breakout mode, and the selected cable length. Contact AICPLIGHT before ordering so the intended port combination and cable option can be checked.

100G QSFP28 Breakout DAC Overview

The 100G QSFP28 Breakout DAC category contains one passive direct attach copper cable for short-distance 100G-to-4×25G Ethernet connections. Q100-4S25-C uses one 100G QSFP28 main connector and four 25G SFP28 branch connectors, dividing the aggregate bandwidth into four independent 25Gb/s links. Available in lengths from 0.5m to 5m, the cable connects a QSFP28 port on a switch or other network device to four SFP28-equipped ports in telecommunications facilities and data centers. It complies with IEEE 802.3bj, SFF-8402, and SFF-8665 specifications.
