Arista Networks QSFP-8LC-AOC20M Compatible 40G QSFP+ to 4 Duplex LC Active Optical Breakout Cable, 20m (66ft)

This 20m (66ft) AOC cable is built for Arista Networks equipment requiring the QSFP-8LC-AOC20M interface. The 40Gbps link uses QSFP+ to 4 duplex LC and is supplied as one complete tested assembly.

OEM Part Number: QSFP-8LC-AOC20MHT Part Number: QSFP-8LC-AOC20M

Product Highlights

• Compatible alternative to Arista Networks QSFP-8LC-AOC20M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 duplex LC
• Fixed length and part number: 20m (66ft), QSFP-8LC-AOC20M
• Minimum bend radius: 30mm

This assembly uses OFNP 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 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.

QSFP-8LC-AOC20M occupies the middle of this family between QSFP-8LC-AOC15M at 15m (49ft) and QSFP-8LC-AOC30M 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 intended application is determined by the host interface and protocol support. Listed interface and protocol references include 10G/40Gigabit Ethernet or Fibre Channel. Confirm that the host firmware and port configuration support the same operating mode.

The QSFP+ to 4 duplex LC 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.

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 assembly is configured for equipment that recognizes QSFP-8LC-AOC20M. Before shipment, we inspect both connectors and verify identification, link establishment and optical link operation, receive activity 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 QSFP-8LC-AOC20M in 20m (66ft). 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.

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, QSFP-8LC-AOC20M and the 20m (66ft) length for easier inventory control.

Standard configurations normally ship within one to three working days. Worldwide courier, air freight and sea freight options are available, and shipments can also be sent on your own courier account or delivered to an appointed forwarder.
