Signal and Lane Configuration

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.

Breakout Port Mapping

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.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

QSFP-4SFP25G-AOC2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

Position Within the Length Range

QSFP-4SFP25G-AOC2M occupies the middle of this family between QSFP-4SFP25G-AOC1M at 1m (3ft) and QSFP-4SFP25G-AOC3M at 3m (10ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Power and Thermal Planning

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.

Cable Construction and Routing

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.

Network and Protocol Considerations

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.

Cisco Compatibility and Factory Testing

Each QSFP-4SFP25G-AOC2M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe optical link operation, receive activity and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Cisco platform should be included with the order.

Ordering Information

Quote HT part number QSFP-4SFP25G-AOC2M with the required quantity. The 2m (7ft) length is fixed for this part number; if a different length is needed, select its corresponding page and OEM reference from the length list above. Standard HT labels and project-specific packaging are available.

Frequently Asked Questions

Is this an original Cisco cable?

No. It is an HT-manufactured compatible alternative for equipment that specifies Cisco QSFP-4SFP25G-AOC2M.

Are separate optical modules required?

No. The connectors and cable form one complete direct-attach assembly. Do not attempt to detach or replace either end.

Can the cable be folded to shorten its routing path?

No. Follow the specified minimum bend radius and route the 2m (7ft) assembly without tight folds, sharp edges or excessive cable ties.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

Quality Assurance and Packaging

Production inspection covers both physical condition and a live link check. Connector ends receive individual protection, and the completed assembly is packed without tight ties or sharp bends. For multi-length projects, cartons can be separated and labelled by OEM part number to simplify installation on site.

Shipping and Lead Time

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
