Cisco QSFP-100G-4SAC Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Copper Breakout Cable

Cisco QSFP-100G-4SAC Compatible 100G QSFP28 4 x 25G NRZ to 4 x 25G SFP28 NRZ Active Copper Breakout Cable

A 100G direct-attached link depends on the correct host identity, interface mode and physical length. This page covers the Cisco QSFP-100G-4SAC compatible ACC series in QSFP28 to 4x SFP28, including 1m (3ft) and 3m (10ft). Each documented length-specific OEM reference is linked separately where an individual product page is available.

Applications and Deployment

Active copper assemblies add signal conditioning while retaining the convenience of a direct-attached cable. They are appropriate where the equipment supports the stated active-cable type and the route exceeds the practical limits of a comparable passive assembly. Per-end power, airflow and host qualification should be assessed before high-density deployment. For this series, the listed interface is QSFP28 to 4x SFP28 and the aggregate rate is 100G. The stated application is 100G/25G Ethernet.

Quality Assurance and Packaging

Each assembly receives a visual connector inspection and functional link check before it is coiled and protected. Packaging is selected to avoid compressing the cable into a tight bundle, and optional rack-based labels help maintain an orderly installation when many identical interfaces are populated together. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.

Cable Construction and Routing

The specification table records the conductor specification is 30AWG; the jacket material is PVC (OFNR); the minimum bend radius is 33mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is 1.8W. Use those values when preparing the rack pathway and receiving checklist. Do not pull a connector by its cable, compress the run under tight ties or force excess length into a sharp coil. Connector protection should remain in place until the assembly is ready for insertion.

High-Density Rack Integration

In a densely populated rack, connector access and airflow are part of the link design. Choose the shortest length that follows the managed path comfortably, avoid tight bundles around the connector housings and preserve room for latch operation. Where power consumption is listed, include every populated interface in the host thermal budget rather than assessing a single cable in isolation. For this series, keep the interface rate, ACC construction and length-specific OEM reference together throughout that review.

Ordering Information

Provide the exact part number, length, quantity and target interface density. For multi-rack projects, list each length separately and identify any preferred carton grouping. Host model and software information can be included for a compatibility review before production or dispatch. For this series, follow the corresponding length link, quote that exact OEM part number and keep different lengths on separate order lines. HT part number QSFP-100G-4SAC identifies the product family; the linked page provides the final length-specific identity.

Cisco Compatibility and Factory Testing

The assembly is evaluated for host recognition and stable link operation, with diagnostics checked where the interface provides them. This approach verifies more than electrical or optical continuity. Exact platform and firmware information remains valuable in high-density deployments because port mode and qualification policy can differ within the same connector family. Series-level inspection is followed by the exact length and OEM configuration selected for dispatch. Functional verification includes link establishment and diagnostic indications where the host exposes them.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.

Frequently Asked Questions

Is this an original Cisco cable?

No. It is an HT-manufactured compatible cable for equipment that specifies QSFP-100G-4SAC, not an original Cisco-branded product.

Are different lengths and OEM part numbers separate products?

Yes. Where a length has its own OEM reference, follow the corresponding link above and order that exact part number on its own line. Do not substitute another length only because the connector arrangement is the same.

Does this ACC cable require separate modules at each end?

No. The connector ends and cable form one complete direct-attach assembly. The ends are not detachable standalone transceivers, and the complete product is tested together.

What information helps confirm compatibility?

Provide the equipment manufacturer and model, port type, hardware revision and software release, together with the required OEM reference, length and quantity. Breakout projects should also identify the intended lane configuration.
