10/100BASE-T SFPJuniper Networks QSFP-100G-1SPC Compatible 100G QSFP28 to 1 x 25G SFP28 Passive Copper Twinax Cable
The QSFP-100G-1SPC compatible series is designed for Juniper Networks hosts requiring a 100G DAC connection. Its QSFP28 to SFP28 arrangement is supplied as a factory-terminated passive twinax link without separate optical modules or patch cords. Use the specifications to assess the physical assembly, then follow the exact length and part-number links when preparing a bill of materials or requesting a compatibility check.

Applications and Deployment
A passive DAC reduces the connection to one factory-terminated electrical assembly. This is useful where low latency, low interface power and a short managed route matter more than optical reach. Cable gauge, connector construction and host port settings still influence whether the complete link operates reliably. For this series, the listed interface is QSFP28 to SFP28 and the aggregate rate is 100G. The stated application is 25G Ethernet, Data Centers.
Juniper Networks 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. 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.
Cable Construction and Routing
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.
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 series, keep the interface rate, DAC construction and length-specific OEM reference together throughout that review.
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. 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.
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.
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. Both connector ends are inspected as part of the complete assembly, and protective packing is selected to avoid tight bends during transport and storage.
Frequently Asked Questions
Is this an original Juniper Networks cable?
No. It is an HT-manufactured compatible cable for equipment that specifies QSFP-100G-1SPC, not an original Juniper Networks-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 DAC 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.
