Juniper Networks QFX-QSFP-DAC-7MA Compatible 40G QSFP+ Active Copper Cable, 7m (23ft)
This QFX-QSFP-DAC-7MA compatible cable gives project teams a defined 40G connection in 7m (23ft), with QSFP+ to QSFP+ and Juniper Networks host compatibility. Rather than treating all lengths as interchangeable, the page keeps this order code separate and links the other verified lengths for accurate schedules, labels and delivery checks.

Juniper Deployment Reference
Juniper platform documentation distinguishes straight QSFP28 DAC or AOC connections from DACBO and AOCBO breakout operation. On channelized systems, the host port must be configured for the required breakout mode. Match this HT compatible cable to the exact Juniper part number and the intended platform configuration.
Network and Protocol Considerations
The intended application is determined by the host interface and protocol support. Listed interface and protocol references include 40G InfiniBand 8x DDR, 4x QDR, 10G/40Gigabit Ethernet, Fibre Channel. 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
This 7m (23ft) assembly is intended for routes that shorter members of the same family cannot serve comfortably. Before ordering, document the actual pathway and the space available for service access. During installation, secure the complete copper assembly and both connector housings without compressing it into an undersized bundle or leaving its weight suspended from the ports. The next verified reach is QFX-QSFP-DAC-10MA at 10m (33ft), but selecting it before measuring the route would introduce additional slack to support.
Position Within the Length Range
QFX-QSFP-DAC-7MA is the shortest of 2 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 QFX-QSFP-DAC-10MA at 10m (33ft), adding 3m for a less direct routing path; selecting it unnecessarily would leave more cable to dress.
Project Documentation and Cable Identification
Large deployments are easier to audit when the order code, physical length and endpoint record agree. Keep the OEM reference in the compatibility document and use the HT part number on the packing list. Where several lengths arrive together, labels and carton groups can be arranged by rack or port plan so installers do not have to identify cables by appearance alone. For this assembly, the listed conductor specification is 26AWG; the minimum bend radius is 37.5mm; the jacket material is PVC (OFNR).
Cable Construction and Routing
This assembly uses 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 37.5mm. 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.
Juniper Networks Compatibility and Factory Testing
Factory verification links the compatibility identity to the exact physical assembly described on this page. Identification, connector condition and live link behavior are checked before packing. Customers can submit equipment and firmware details with the project documentation for a more specific pre-order compatibility review. Where supported by the host, link stability and diagnostic indications are reviewed together with the established link.
Frequently Asked Questions
Is this an original Juniper Networks cable?
No. It is an HT-manufactured compatible alternative for equipment that specifies Juniper Networks QFX-QSFP-DAC-7MA.
Are separate transceivers or patch leads required?
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
Can excess cable be folded into a compact bundle?
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Will any matching connector operate at the same speed?
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
Ordering Information
Use the listed HT part number for ordering and retain the OEM reference as the host-compatibility cross-reference. Send quantities by length, along with any rack-based packing or label instructions. If the project has mixed equipment, include the host model for each group rather than relying only on the aggregate cable rate. Keep QFX-QSFP-DAC-7MA associated with 7m (23ft) throughout the order and receiving record.
Shipping and Lead Time
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
Quality Assurance and Packaging
Inspection and link testing are completed before the cable enters its protective packaging. Project orders can be packed and labelled by length, rack or customer reference, with packing documentation that makes received quantities straightforward to reconcile against the installation schedule. Standard protective packing is used by default, with project documentation arranged when requested.
