Arista Networks QSFP-4 x 10G-AOC3M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Optical Breakout Cable, 3m (10ft)

This 3m (10ft) AOC cable is built for Arista Networks equipment requiring the QSFP-4 x 10G-AOC3M interface. The 40Gbps link uses QSFP+ to 4 SFP+ and is supplied as one complete tested assembly.

OEM Part Number: QSFP-4 x 10G-AOC3MHT Part Number: QSFP-4 x 10G-AOC3M

Product Highlights

• Compatible alternative to Arista Networks QSFP-4 x 10G-AOC3M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 3m (10ft), QSFP-4 x 10G-AOC3M
• 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 QSFP+ to 4 SFP+ 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.

At 3m (10ft), this assembly can bridge non-aligned ports or adjacent racks while remaining a single direct-attach link. Support longer horizontal runs with suitable cable management and preserve space for cooling and future maintenance.

QSFP-4 x 10G-AOC3M occupies the middle of this family between QSFP-4 x 10G-AOC2M at 2m (7ft) and QSFP-4 x 10G-AOC5M at 5m (16ft). It adds 1m over the shorter option for extra routing clearance, while the next longer version adds another 2m. 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.

Compatibility is more than matching the QSFP+ to 4 SFP+ shape. This assembly is prepared for hosts expecting QSFP-4 x 10G-AOC3M 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 QSFP-4 x 10G-AOC3M, cable length 3m (10ft) 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.

Quality control includes connector appearance, cable identification and functional verification. Packing materials are selected to keep the connector housings and cable boots from taking impact during transport, and the coil is not compressed into an undersized bundle. Volume orders can include customer-specific labels and packing documentation.

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.
