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

For short, high-density connections, this AOC cable combines 40G performance with a fixed 3m (10ft) cable run. It corresponds to Cisco QSFP-4 x 10G-AOC3M and uses a factory-terminated active optical link with the optical engines and fiber integrated into the assembly.

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

Product Highlights

• Compatible alternative to Cisco 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.

For this Cisco application, testing combines digital identification with actual traffic-link verification and optical link operation, receive activity and diagnostic readouts. Both ends are inspected for latch, boot and connector damage. If the project uses a specific hardware revision or a channelized port, send those details so that the intended configuration can be reviewed before shipment.

This product is ordered as QSFP-4 x 10G-AOC3M in 3m (10ft). 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.

Every QSFP-4 x 10G-AOC3M compatible assembly undergoes link testing, compatibility verification and visual inspection. The 3m (10ft) 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.

Stock items are generally dispatched within one to three working days after order confirmation. DHL, UPS, FedEx, TNT and EMS are available for international delivery; larger consolidated orders can move by air or sea freight. Customer courier accounts and nominated forwarders are accepted.
