Arista Networks CAB-O-O-400G-2M Compatible 400G OSFP 8 x 50G PAM4 IHS/Finned Top Passive Copper Twinax Cable, 2m (7ft)

With a fixed 2m (7ft) cable and OSFP (IHS/Finned Top) to OSFP (IHS/Finned Top), the CAB-O-O-400G-2M compatible assembly simplifies 400G deployment. It is manufactured and tested by HT for Arista Networks equipment.

The listed modulation format is 8x 50G-PAM4. 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 intended application is determined by the host interface and protocol support. Listed interface and protocol references include OSFP MSA, IEEE 802.3cd 100GBase-CR2, CMIS 4.0. 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.

CAB-O-O-400G-2M provides 2m (7ft) for connections between separated rack units or nearby equipment positions. Plan the route around cable managers and power cords, keeping the assembly free from connector strain while avoiding a large obstruction in the airflow path.

CAB-O-O-400G-2M occupies the middle of this family between CAB-O-O-400G-1M at 1m (3ft) and CAB-O-O-400G-2.5M at 2.5m (8ft). It adds 1m 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 rated power consumption is 0.1W 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 28AWG conductors, PVC jacket, minimum bend radius 40.5mm. 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 HT cable carries the compatibility configuration associated with CAB-O-O-400G-2M, while its mechanical assembly remains the fixed 2m (7ft) 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.

Use part number CAB-O-O-400G-2M for the 2m (7ft) assembly. For mixed-length projects, list each required part number and quantity separately so that every cable can be tested and packed according to its intended installation.

Every CAB-O-O-400G-2M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 2m (7ft) 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.

Lead time for ordinary configurations is normally one to three working days, while production quantities are confirmed with the order. We can arrange express courier or economy freight according to destination and carton volume, or hand the shipment to your appointed logistics provider.
