Arista Networks A-Q200-Q200-20M Compatible 200G QSFP56 4 x 50G PAM4 Active Optical Cable, 20m (66ft)

This HT cable matches the A-Q200-Q200-20M requirement for Arista Networks equipment. The 20m (66ft) assembly supports 200G operation and provides a factory-terminated active optical link with the optical engines and fiber integrated into the assembly; its complete electrical and mechanical details are listed below.

OEM Part Number: A-Q200-Q200-20MHT Part Number: A-Q200-Q200-20M

Product Highlights

• Maximum power consumption: 4.35W Per End
• Minimum bend radius: 30mm
• Operating temperature: 0 to 70°C (32 to 158°F)

The listed modulation format is 4x 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.

This assembly uses LSZH jacket, minimum bend radius 30mm. 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 IEEE 802.3, QSFP56 MSA, SFF-8665, SFF-8636. Confirm that the host firmware and port configuration support the same operating mode.

The optical engines and fiber are permanently integrated into this AOC. There are no detachable optical modules to clean or exchange. Handle the complete assembly by its connector housings and cable, and keep both ends matched to the same interface specification.

The extended 20m (66ft) reach supports connections across adjacent racks or between separated equipment rows. Secure the cable along its route, protect both ends from pull loads and preserve ventilation. The integrated AOC construction avoids a chain of separate modules and patch leads.

A-Q200-Q200-20M occupies the middle of this family between A-Q200-Q200-15M at 15m (49ft) and A-Q200-Q200-30M at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 10m. 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 4.35W 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.

Compatibility is more than matching the QSFP56 to QSFP56 shape. This assembly is prepared for hosts expecting A-Q200-Q200-20M and is checked for identification, stable link behavior and optical link operation, receive activity and diagnostic readouts. We recommend confirming the equipment model and software release for critical deployments or mixed-vendor installations.

When ordering, specify A-Q200-Q200-20M, cable length 20m (66ft) 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, A-Q200-Q200-20M and the 20m (66ft) length for easier inventory control.

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.
