Cisco QSFP-4SFP25G-AOC3M Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Optical Breakout Cable, 3m (10ft)

The QSFP-4SFP25G-AOC3M cable offers a direct QSFP28 to 4x SFP28 connection at 100Gbps. Its 3m (10ft) length and AOC construction are intended for Cisco equipment, with no separate transceiver-and-patch-cord assembly required.

The listed modulation format is QSFP28-4x 25G-NRZ SFP28-1x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

QSFP-4SFP25G-AOC3M occupies the middle of this family between QSFP-4SFP25G-AOC2M at 2m (7ft) and QSFP-4SFP25G-AOC5M at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is 2.2W (QSFP28 End)0.8W (SFP28 Per End). Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

This assembly uses OFNP jacket, minimum bend radius 30mm. These mechanical characteristics affect how the cable should be dressed behind the equipment. Avoid sharp edges, excessive ties and repeated tight bends close to the connector boots.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP28 MSA, SFP28 MSA. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP28 to 4x SFP28 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

The HT cable carries the compatibility configuration associated with QSFP-4SFP25G-AOC3M, while its mechanical assembly remains the fixed 3m (10ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Cisco software can request a pre-order check.

Use part number QSFP-4SFP25G-AOC3M for the 3m (10ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QSFP-4SFP25G-AOC3M and the 3m (10ft) length for easier inventory control.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
