Arista C-Z100-2S50-2M Compatible 100G SFP-DD 2 x 50G PAM4 to 2 x SFP56 50G PAM4 Passive Copper Twinax Cable, 2m (7ft)

Designed for hosts that recognize C-Z100-2S50-2M, this SFP-DD to 2x SFP56 cable delivers 100G transmission over a fixed 2m (7ft) assembly. Its DAC construction provides a factory-terminated passive copper link without separate optical modules or patch cords.

The listed modulation format is SFP-DD-2x 50G-PAM4SFP56-1x 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.

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.

C-Z100-2S50-2M 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.

C-Z100-2S50-2M occupies the middle of this family between C-Z100-2S50-1M at 1m (3ft) and C-Z100-2S50-3M at 3m (10ft). It adds 1m 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 25.2mm. 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, 128G Fibre Channel. Listed interface and protocol references include SFPDD: SFP-DD MSA, SFP-DD MIS, IEEE 802.3cdSFP56: SFF-8432, SFF-8402, SFF-8472, IEEE 802.3cd. Confirm that the host firmware and port configuration support the same operating mode.

The SFP-DD to 2x SFP56 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.

Each C-Z100-2S50-2M compatible cable is powered up on a suitable test interface rather than checked only for continuity. We confirm the expected identification and observe electrical continuity, link stability and diagnostic readouts. Because operating systems can apply different qualification rules by hardware revision, the intended Arista platform should be included with the order.

Use part number C-Z100-2S50-2M 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 C-Z100-2S50-2M 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.

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.
