Arista Networks CAB-D-8S-200G-1.5M Compatible 200G QSFP-DD 8 x 25G NRZ to 8 x 25G SFP28 25G NRZ Passive Copper Breakout Cable, 1.5m (5ft)

For short, high-density connections, this DAC cable combines 200G performance with a fixed 1.5m (5ft) cable run. It corresponds to Arista Networks CAB-D-8S-200G-1.5M and uses a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is QSFP-DD-8x 25G-NRZSFP28-25G-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 0.1W (QSFP-DD End)0.1W (SFP28 Per End). 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 22.5mm. 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.

The intended application is determined by the host interface and protocol support. Listed interface and protocol references include QSFP-DD MSA, SFF-8432, IEEE 802.3bs-200GAUI-8, IEEE802.3by-25GAUI, CMIS 4.0, SFF-8472. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP-DD to 8x 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 additional half metre beyond a one-metre assembly gives CAB-D-8S-200G-1.5M useful routing flexibility when the ports are not directly aligned. It can accommodate a different rack unit or a short service loop, but excess cable should be dressed loosely rather than folded into a tight coil.

CAB-D-8S-200G-1.5M occupies the middle of this family between CAB-D-8S-200G-1M at 1m (3ft) and CAB-D-8S-200G-2M at 2m (7ft). It adds 0.5m over the shorter option for extra routing clearance, while the next longer version adds another 0.5m. Measure the managed path and choose this version when its reach is sufficient without creating the slack associated with the longer assembly.

The HT cable carries the compatibility configuration associated with CAB-D-8S-200G-1.5M, while its mechanical assembly remains the fixed 1.5m (5ft) version described here. Incoming inspection, connector examination and a live link test are completed before packing. Customers with unusually old or new Arista Networks software can request a pre-order check.

This product is ordered as CAB-D-8S-200G-1.5M in 1.5m (5ft). 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-D-8S-200G-1.5M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 1.5m (5ft) 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.
