Cisco QSFP-4SFP25G-AOC5M Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Optical Breakout Cable, 5m (16ft)

For short, high-density connections, this AOC cable combines 100G performance with a fixed 5m (16ft) cable run. It corresponds to Cisco QSFP-4SFP25G-AOC5M and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

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 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 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.

The 5m (16ft) length gives QSFP-4SFP25G-AOC5M more freedom for adjacent-rack and row-end deployments. The integrated optical assembly should be supported along its route without tight bends or connector pull loads; the AOC specification and host support must still match the intended link.

QSFP-4SFP25G-AOC5M occupies the middle of this family between QSFP-4SFP25G-AOC3M at 3m (10ft) and QSFP-4SFP25G-AOC7M at 7m (23ft). It adds 2m 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 HT cable carries the compatibility configuration associated with QSFP-4SFP25G-AOC5M, while its mechanical assembly remains the fixed 5m (16ft) 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.

When ordering, specify QSFP-4SFP25G-AOC5M, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Every QSFP-4SFP25G-AOC5M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 5m (16ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
