Arista Networks CAB-S-S-25G-5M Compatible 25G SFP28 Passive Copper Twinax Cable, 5m (16ft)

The CAB-S-S-25G-5M cable offers a direct SFP28 to SFP28 connection at 25Gbps. Its 5m (16ft) length and DAC construction are intended for Arista Networks equipment, with no separate transceiver-and-patch-cord assembly required.

OEM Part Number: CAB-S-S-25G-5MHT Part Number: CAB-S-S-25G-5M

Product Highlights

• Compatible alternative to Arista Networks CAB-S-S-25G-5M
• 25G connectivity at 25Gbps
• Interface configuration: SFP28 to SFP28
• Fixed length and part number: 5m (16ft), CAB-S-S-25G-5M
• Conductor specification: 26AWG
• Minimum bend radius: 28mm

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 28mm. 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 25G Ethernet, Data Center, 5G Wireless. Listed interface and protocol references include IEEE 802.3, SFP28 MSA, SFF-8402, Infiniband, EIA 364-1000. Confirm that the host firmware and port configuration support the same operating mode.

A passive DAC has no separate optical conversion stage. Its low-power, low-latency operation is useful for short equipment links, but the assembly must remain within the length and signaling mode accepted by both hosts.

The 5m (16ft) length gives CAB-S-S-25G-5M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

CAB-S-S-25G-5M is the longest of 7 verified length options in this family. Compared with CAB-S-S-25G-4M at 4m (13ft), it provides 1m 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.

Compatibility is more than matching the SFP28 to SFP28 shape. This assembly is prepared for hosts expecting CAB-S-S-25G-5M and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

Use part number CAB-S-S-25G-5M for the 5m (16ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

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.
