Arista Networks AOC-Q-4S-100G-50M Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Optical Breakout Cable, 50m (164ft)

The HT-manufactured AOC-Q-4S-100G-50M compatible cable provides 100G connectivity for Arista Networks equipment. This 50m (164ft) version is a factory-terminated active optical link with the optical engines and fiber integrated into the assembly, with an exact part number and length that can be matched directly to the equipment requirement.

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 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 extended 50m (164ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

AOC-Q-4S-100G-50M is the longest of 11 verified length options in this family. Compared with AOC-Q-4S-100G-30M at 30m (98ft), it provides 20m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

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.

Each AOC-Q-4S-100G-50M 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 Arista Networks platform should be included with the order.

This product is ordered as AOC-Q-4S-100G-50M in 50m (164ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Every AOC-Q-4S-100G-50M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 50m (164ft) 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.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
