For equipment that specifies Arista Networks QSFP-100G-1SPC, this HT-manufactured DAC family offers 100G direct-attach connectivity with QSFP28 to SFP28. Rather than treating different OEM length codes as interchangeable, the available configurations below link to their own product pages. Mechanical details, installation planning and factory checks are included for engineering and purchasing review.

The documented series configuration is 1m (3ft). Use the relevant OEM reference below together with the HT identity and required length when requesting a quotation. If another length carries a different OEM part number, it must be reviewed and ordered as that distinct configuration.

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air. For this series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.
Passive twinax cables are commonly selected for short switch-to-switch, switch-to-server and accelerator connections within or between nearby racks. With no separate optical conversion stage, they offer a simple low-power physical link. The assembly must nevertheless remain within the length, signaling rate and qualification limits accepted by both hosts. For this series, the listed interface is QSFP28 to SFP28 and the aggregate rate is 100G. The stated application is 25G Ethernet, Data Centers.
For this assembly, the conductor specification is 26AWG; the jacket material is PVC (OFNR); the minimum bend radius is 30mm; the operating temperature is 0 to 70°C (32 to 158°F); the power consumption is ≤0.1W. These parameters belong in the installation review rather than being treated as catalogue trivia. Route the cable through its intended managers without tension, avoid pressure close to the connector boots and leave enough space to operate the latches. Any service loop must respect the stated bend limit.
The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.
Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. 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.
When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. 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-1SPC identifies the product family; the linked page provides the final length-specific identity.
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.
No. It is an HT-manufactured compatible cable for equipment that specifies QSFP-100G-1SPC, not an original Arista Networks-branded product.
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.
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.
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.
