Juniper Networks QFX-QSFP28-DAC-5M Compatible 100G QSFP28 4 x 25G NRZ Passive Copper Twinax Cable, 5m (16ft)

This 5m (16ft) DAC cable is built for Juniper Networks equipment requiring the QFX-QSFP28-DAC-5M interface. The 100Gbps link uses QSFP28 to QSFP28 and is supplied as one complete tested assembly.

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.

QFX-QSFP28-DAC-5M is the longest of 7 verified length options in this family. Compared with QFX-QSFP28-DAC-3M at 3m (10ft), it provides 2m of additional reach for a longer vertical drop, a wider rack or an adjacent-cabinet route. Confirm that the complete path requires this length, because unused slack still needs supported, bend-safe storage.

The listed modulation format is 4x 25G-NRZ to 4x 25G-NRZ. Both host interfaces must be configured for the same aggregate rate and lane arrangement. A connector that fits mechanically does not by itself guarantee that the remote port supports this encoding or breakout mode.

The rated power consumption is ≤0.5W. 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 26AWG conductors, PVC (OFNR) jacket, minimum bend radius 45mm. 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 100G Ethernet. Listed interface and protocol references include QSFP28 MSA, SFF-8662, IEEE 802.3. Confirm that the host firmware and port configuration support the same operating mode.

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.

The 5m (16ft) length gives QFX-QSFP28-DAC-5M more freedom for adjacent-rack and row-end deployments. Longer copper runs need particular attention to routing weight and bend control; the DAC specification and host support must still match the intended link.

The HT cable carries the compatibility configuration associated with QFX-QSFP28-DAC-5M, while its mechanical assembly remains the fixed 5m (16ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Juniper Networks software can request a pre-order check.

When ordering, specify QFX-QSFP28-DAC-5M, cable length 5m (16ft) and the host platform. This allows our team to verify both the physical assembly and the compatibility requirement before production. Neutral labeling and customer packing lists can be arranged for volume orders.

HT inspects and tests every completed cable before it enters finished stock. Protective caps or covers are fitted where applicable, followed by anti-static or tray packaging and an outer carton. Custom labels can cross-reference the customer part number, QFX-QSFP28-DAC-5M and the 5m (16ft) length for easier inventory control.

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.
