SFP28 to SFP28-25G-DAC-2.5M8FT 25G SFP28 Passive Copper Twinax Cable, 2.5m (8ft)

SFP28 to SFP28-25G-DAC-2.5M8FT 25G SFP28 Passive Copper Twinax Cable, 2.5m (8ft)

The SFP28 to SFP28-25G-DAC-2.5M8FT compatible cable combines 25G DAC connectivity with a defined 2.5m (8ft) pathway between SFP28 to SFP28 interfaces. It is intended for Generic equipment and is documented here as a distinct order code, allowing cable schedules, service access and related length selections to be reviewed before installation.

Cable Construction and Routing

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 21.25mm. 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.

Position Within the Length Range

SFP28 to SFP28-25G-DAC-2.5M8FT occupies the middle of this family between SFP28 to SFP28-25G-DAC-2M7FT at 2m (7ft) and SFP28 to SFP28-25G-DAC-3M10FT at 3m (10ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Structured Pathways and Serviceability

Treat the direct-attach assembly as part of the permanent pathway plan even when the link is expected to be temporary. Follow the intended horizontal and vertical managers, maintain the specified bend radius and leave service access around both ports. A small, supported service allowance is preferable to excess slack concealed inside a rack or placed under cable-tie pressure. For this assembly, the listed conductor specification is 30AWG; the minimum bend radius is 21.25mm; the jacket material is PVC (OFNR).

Network and Protocol Considerations

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.

Passive Copper Operation

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.

Length Selection and Installation Planning

The 2.5m (8ft) version is useful when a two-metre run would leave insufficient working slack. Before installation, check the complete horizontal and vertical path so that SFP28 to SFP28-25G-DAC-2.5M8FT reaches both ports without tension at either connector.

Ordering Information

Include the part number, fixed length, quantity and required pathway or rack grouping in the order information. The host model and firmware release are useful for change-controlled deployments. Different lengths should remain separate order lines so delivered labels and packing records agree with the pathway plan. This page’s fixed configuration is 2.5m (8ft); another length must be quoted under its corresponding part number.

Generic Compatibility and Factory Testing

Verification covers the physical connectors, expected host identity and an operating link with available diagnostic indications. We distinguish this complete check from a simple continuity test. Platform model and software release can be reviewed in advance where the installation has strict documentation or change-control requirements. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.

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. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.

Quality Assurance and Packaging

After connector inspection and link verification, the assembly is coiled without tight bends and packed with end protection. Labels can cross-reference the customer cable schedule, OEM part number and length. This supports both receiving checks and later moves, adds or changes. Volume orders can include customer references on the labels and carton list.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

No. It is manufactured by HT under our own manufacturer identity.

Does this order code cover multiple lengths?

No. SFP28 to SFP28-25G-DAC-2.5M8FT refers here to 2.5m (8ft). Every other verified length has a separate part number and page in the length list.

Are separate transceivers or patch leads required?

No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.

Can excess cable be folded into a compact bundle?

No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
