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-1M3FT is the shortest of 7 verified length options in this family. It is the preferred choice when the port positions are close and cable slack must be kept to a minimum. The next option is SFP28 to SFP28-25G-DAC-1.5M5FT at 1.5m (5ft), adding 0.5m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.

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

At 1m (3ft), SFP28 to SFP28-25G-DAC-1M3FT is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

Generic Compatibility and Factory Testing

The HT cable carries the compatibility configuration associated with SFP28 to SFP28-25G-DAC-1M3FT, while its mechanical assembly remains the fixed 1m (3ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Generic software can request a pre-order check.

Ordering Information

When ordering, specify SFP28 to SFP28-25G-DAC-1M3FT, cable length 1m (3ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

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

Are separate optical modules required?

No. The connectors and cable form one complete direct-attach assembly. Do not attempt to detach or replace either end.

Can the cable be folded to shorten its routing path?

No. Follow the specified minimum bend radius and route the 1m (3ft) assembly without tight folds, sharp edges or excessive cable ties.

Can I use it between different speeds or interface types?

Only when both hosts explicitly support the same data rate, lane mapping and breakout configuration. Mechanical fit alone is not proof of interoperability.

Quality Assurance and Packaging

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.

Shipping and Lead Time

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
