Arista Networks AOC-S-S-25G-4M Compatible 25G SFP28 Active Optical Cable, 4m (13ft)

Designed for hosts that recognize AOC-S-S-25G-4M, this SFP28 to SFP28 cable delivers 25G transmission over a fixed 4m (13ft) assembly. Its AOC construction provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

OEM Part Number: AOC-S-S-25G-4MHT Part Number: AOC-S-S-25G-4M

Product Highlights

• Compatible alternative to Arista Networks AOC-S-S-25G-4M
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 4m (13ft), AOC-S-S-25G-4M
• Minimum bend radius: 30mm

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.

AOC-S-S-25G-4M occupies the middle of this family between AOC-S-S-25G-3M at 3m (10ft) and AOC-S-S-25G-5M at 5m (16ft). 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.

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 4m (13ft) length gives AOC-S-S-25G-4M 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.

Compatibility is more than matching the SFP28 to SFP28 shape. This assembly is prepared for hosts expecting AOC-S-S-25G-4M and is checked for identification, stable link behavior and optical link operation, receive activity and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Quote HT part number AOC-S-S-25G-4M with the required quantity. The 4m (13ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
