Signal and Lane Configuration

The listed modulation format is QSFP28-4x 25G-NRZ SFP28-1x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

Network and Protocol Considerations

The intended application is 100G/25G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFP28 MSA, SFF-8665, SFF-8679, SFF-8472, SFF-8402. Confirm that the host firmware and port configuration support the same operating mode.

Breakout Port Mapping

The QSFP28 to 4x SFP28 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 extended 7m (23ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated DAC construction avoids a chain of separate modules and patch leads.

Position Within the Length Range

QSFP28 to 4x SFP28-100G-DAC-7M23FT occupies the middle of this family between QSFP28 to 4x SFP28-100G-DAC-5M16FT at 5m (16ft) and QSFP28 to 4x SFP28-100G-DAC-9M29FT at 9m (29ft). It adds 2m over the shorter option for extra routing clearance, while the next longer version adds another 2m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

Power and Thermal Planning

The rated power consumption is 1.8W. Include this load in the host-port power and thermal budget, especially in densely populated switches. Maintain front-panel clearance and do not bundle the cable so tightly that it obstructs airflow around the connectors.

Cable Construction and Routing

This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 44.5mm. 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.

Generic Compatibility and Factory Testing

For this Generic application, testing combines digital identification with actual traffic-link verification and electrical continuity, link stability and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

Ordering Information

Quote HT part number QSFP28 to 4x SFP28-100G-DAC-7M23FT with the required quantity. The 7m (23ft) 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.

Frequently Asked Questions

Is this an original equipment manufacturer cable?

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

Does this page include more than one cable length?

No. This page is dedicated to 7m (23ft) and part number QSFP28 to 4x SFP28-100G-DAC-7M23FT. Other lengths have their own part numbers and product pages.

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 7m (23ft) assembly without tight folds, sharp edges or excessive cable ties.

Quality Assurance and Packaging

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QSFP28 to 4x SFP28-100G-DAC-7M23FT and the 7m (23ft) length for easier inventory control.

Shipping and Lead Time

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
