Specifications

Signal and Lane Configuration

The listed modulation format is 4x 25G-NRZ to 4x 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.

Length Selection and Installation Planning

With 25m (82ft) available, the installer has more routing freedom but also more cable to control. Determine where any remaining service loop will be stored, preserve the stated bend radius and keep the loop away from sharp edges and hot exhaust. The integrated optical cable and both optical engines should remain accessible for inspection and removal. Within this family, AOC-Q-Q-100G-20M is shorter at 20m (66ft), while AOC-Q-Q-100G-30M is the next longer choice at 30m (98ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

AOC-Q-Q-100G-25M occupies the middle of this family between AOC-Q-Q-100G-20M at 20m (66ft) and AOC-Q-Q-100G-30M at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Data-Center Design and Airflow

Select the assembly by both reach and rack layout. A direct connection removes separate module-and-patch-cord interfaces, but it still needs a bend-safe pathway and clear connector access. Keep cable bundles from blocking front-panel airflow, account for the listed interface power where applicable and choose a length that supports maintenance without leaving an unmanaged coil. For this assembly, the minimum bend radius is 30mm; the stated power consumption is <2.2W; the jacket material is OFNP.

Power and Thermal Planning

The rated power consumption is <2.2W. 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 100G Ethernet. Listed interface and protocol references include IEEE 802.3 bm, SFF-8665. Confirm that the host firmware and port configuration support the same operating mode.

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.

Quality Assurance and Packaging

Each cable receives connector inspection and a functional link check before it is coiled with bend-safe slack and packed. Protective materials shield the connector housings during transport. Rack or project labels are available to keep length, part number and installation destination aligned. Standard protective packing is used by default, with project documentation arranged when requested.

Ordering Information

Provide the OEM reference, HT part number, fixed length and quantity, together with the intended host interfaces. Rack-based quantities and packaging instructions can be included for larger deployments. Other lengths are separate products and should be entered on their own order lines. Quantity and any labeling instructions should be attached specifically to AOC-Q-Q-100G-25M.

Arista Networks Compatibility and Factory Testing

Compatibility confirmation combines host identification with actual link establishment and diagnostic checks. The assembly is prepared for the stated OEM reference rather than selected only by connector shape. For a new data-center deployment, the equipment model, port mode and software release provide the most useful basis for a pre-order review. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.

Frequently Asked Questions

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
