Arista Networks CAB-Q-2Q-100G-1M Compatible 100G QSFP28 4 x 25G NRZ to 2 x 50G QSFP28 2 x 25G NRZ Passive Copper Breakout Cable, 1m (3ft)

The HT-manufactured CAB-Q-2Q-100G-1M compatible cable provides 100G connectivity for Arista Networks equipment. This 1m (3ft) version is a factory-terminated passive copper link without separate optical modules or patch cords, with an exact part number and length that can be matched directly to the equipment requirement.

The listed modulation format is QSFP28-4x 25G-NRZ SFP28-2x 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.

At 1m (3ft), CAB-Q-2Q-100G-1M is a practical choice for direct connections within one rack. Route the cable along the intended management path rather than pulling it diagonally across adjacent connectors, and leave enough clearance for insertion, removal and front-panel airflow.

CAB-Q-2Q-100G-1M occupies the middle of this family between CAB-Q-2Q-100G-0.5M at 0.5m (2ft) and CAB-Q-2Q-100G-2M at 2m (7ft). 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 0.5W. 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 30AWG conductors, PVC (OFNR) jacket, minimum bend radius 10D/5D (Dynamic/Static). 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/50G Ethernet, 128G Fibre Channel. Listed interface and protocol references include IEEE 802.3, QSFP28 MSA, SFP-8665, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP28 to 2x SFP28 configuration divides the high-speed interface into multiple lower-speed connections. Verify the upstream lane assignment, downstream port speeds and breakout setting on the host before connecting the assembly. Each branch must attach to the correct remote interface.

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 assembly is configured for equipment that recognizes CAB-Q-2Q-100G-1M. Before shipment, we inspect both connectors and verify identification, link establishment and electrical continuity, link stability and diagnostic readouts. Host hardware and firmware revisions can affect third-party cable acceptance, so customers can provide the equipment model and software release for a pre-order compatibility review.

This product is ordered as CAB-Q-2Q-100G-1M in 1m (3ft). 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.

Every CAB-Q-2Q-100G-1M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1m (3ft) cable is coiled without exceeding its minimum bend radius, fitted with connector protection and packed in an anti-static bag or protective tray before cartoning. Project labels and packing lists are available for volume orders.

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.
