Cisco SFP-H25G-CU Compatible 25G SFP28 Passive Copper Twinax Cable

Cisco SFP-H25G-CU Compatible 25G SFP28 Passive Copper Twinax Cable

Use this DAC cable where a 25G link is required between compatible direct-attach ports. This HT version corresponds to Cisco SFP-H25G-CU and covers 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 4m (13ft) and 5m (16ft); electrical or optical construction follows the DAC specification rather than a detachable transceiver-and-patch-cord arrangement.

Applications and Deployment

Passive DAC assemblies are normally used for short switch-to-switch, switch-to-server and rack-adjacent links. They draw very little power and avoid separate optical components, but the selected length must remain within the host and cable specification.

The the stated connector configuration interface and 25G data rate must match the equipment at both ends. The source application is listed as 25G Ethernet, Data Center, 5G Wireless. For breakout versions, confirm the lane mapping and the speed of every downstream port; matching connector shapes alone does not establish interoperability.

Cisco Compatibility and Testing

The assembly is configured for equipment that recognizes the SFP-H25G-CU series. Before shipment, we check connector identification, link establishment and electrical link stability, signal integrity and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the switch, server or accelerator model and software release for a pre-order compatibility review.

Ordering Information

Quote HT part number SFP-H25G-CU, the required length from 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 4m (13ft) and 5m (16ft), and the OEM part number used by your equipment. The length-specific OEM identifiers above link to their own product pages so each reference can be ordered separately.

Frequently Asked Questions

Is this an original Cisco cable?

No. It is an HT-manufactured compatible cable for equipment that specifies SFP-H25G-CU, not an original Cisco-branded product.

Which lengths are covered by this product page?

This series page covers 1m (3ft), 1.5m (5ft), 2m (7ft), 2.5m (8ft), 3m (10ft), 4m (13ft) and 5m (16ft). These are the length configurations identified from the source product records; contact us if a different project length is required.

Can this DAC cable connect different port speeds or breakout configurations?

Only when both host ports support the exact aggregate rate, lane mapping and breakout mode stated in the specifications. Confirm the equipment models before connecting unlike interface versions.

Does the cable need separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. Do not attempt to detach the ends or treat the assembly as two independent modules.

Quality Assurance and Packaging

Every DAC assembly undergoes continuity and link testing, compatibility verification and a visual inspection of both connector ends. Cables are coiled without exceeding their minimum bend radius, fitted with connector protection and packed in anti-static bags or protective trays before cartoning. Project labels and packing lists are available for volume orders.

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.
