Juniper Networks QFX-SFP-DAC-3M Compatible 10G SFP+ Passive Copper Twinax Cable, 3m (10ft)

This 3m (10ft) DAC cable is built for Juniper Networks equipment requiring the QFX-SFP-DAC-3M interface. The 10Gbps link uses SFP+ to SFP+ and is supplied as one complete tested assembly.

OEM Part Number: QFX-SFP-DAC-3MHT Part Number: QFX-SFP-DAC-3M

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.

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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

QFX-SFP-DAC-3M occupies the middle of this family between EX-SFP-10GE-DAC-2.5M at 2.5m (8ft) and EX-SFP-10GE-DAC-4M at 4m (13ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 1m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The rated power consumption is ≤0.1W. 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.

This assembly uses 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 23mm. 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.

The intended application is 10G Ethernet. Listed interface and protocol references include 1x InfiniBand QDR, DDR, SDR, 10 Gigabit Ethernet, Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

Compatibility is more than matching the SFP+ to SFP+ shape. This assembly is prepared for hosts expecting QFX-SFP-DAC-3M and is checked for identification, stable link behavior and electrical continuity, link stability and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

This product is ordered as QFX-SFP-DAC-3M in 3m (10ft). Include the equipment model and software release if you would like a pre-order compatibility review. Other lengths use different part numbers and should not be substituted into the same order line.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
