A successful 40G link depends on host acceptance as well as physical fit. This QSFP-4 x 10G-AOC3M compatible AOC assembly combines QSFP+ to 4 SFP+ with a fixed 3m (10ft) cable for Arista Networks equipment. The specifications, configuration guidance and live-link factory verification below describe the exact product supplied under this reference.

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 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.
Check three layers before deployment: the host must accept the cable identification, the port must support the stated aggregate rate, and the lane configuration must match the attached interfaces. On breakout hardware, also confirm channelization and the mapping of every branch. These checks are particularly important when similar-looking ports operate at different speeds or under different firmware settings. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.
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 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.
Specify the OEM part number and fixed length, then provide the intended host configuration if the link uses channelized or breakout ports. Separate part numbers should be used for separate lengths. This gives the compatibility review enough information to check both the physical assembly and the intended operating mode. This page’s fixed configuration is 3m (10ft); another length must be quoted under its corresponding part number.
The verification process combines digital identification with a live link test and diagnostic observation. Host model, hardware revision and software release are useful inputs because qualification behavior can change between platform generations; those details allow platform-specific requirements to be reviewed before the cable is packed. The check includes receive activity and diagnostic indications, followed by a final inspection of both ends.
Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. Worldwide courier services are available, with air or sea freight for consolidated shipments; freight-collect delivery and coordination with a customer’s logistics provider can be arranged.
Functional inspection covers identification, link establishment and the condition of both connector assemblies. The cable is then protected against dust and connector damage and packed without sharp bends. Labels can include the customer reference and host-platform note when requested for a controlled deployment. Neutral packaging and customer-specific packing documentation are available on request.
No. It is an HT-manufactured compatible alternative for equipment that specifies Arista Networks QSFP-4 x 10G-AOC3M.
No. This is one complete direct-attach assembly. The ends are not detachable modules and should not be separated from the cable.
No. Use a supported, bend-safe service loop and observe the listed minimum bend radius. Do not crease the cable or tighten ties around the connector boots.
Not necessarily. Both hosts must support the stated rate, identification, lane mapping and any required breakout configuration; mechanical compatibility alone is insufficient.
