Dell CBL-QSFP-4 x 10G-AOC25M Compatible 40G QSFP+ to 4 x 10G SFP+ Active Optical Breakout Cable, 25m (82ft)

Use the CBL-QSFP-4 x 10G-AOC25M compatible assembly where a 40G connection is required between compatible ports. This page covers the 25m (82ft) version only, with its own HT part number, specifications and compatibility verification.

OEM Part Number: CBL-QSFP-4 x 10G-AOC25MHT Part Number: CBL-QSFP-4 x 10G-AOC25M

Product Highlights

• Compatible alternative to Dell CBL-QSFP-4 x 10G-AOC25M
• 40G connectivity at 40Gbps
• Interface configuration: QSFP+ to 4 SFP+
• Fixed length and part number: 25m (82ft), CBL-QSFP-4 x 10G-AOC25M
• 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 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 25m (82ft) 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.

CBL-QSFP-4 x 10G-AOC25M occupies the middle of this family between CBL-QSFP-4 x 10G-AOC20M at 20m (66ft) and CBL-QSFP-4 x 10G-AOC30M at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 5m. 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 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.

Our compatibility setup for Dell CBL-QSFP-4 x 10G-AOC25M is checked together with the physical 25m (82ft) assembly. Factory verification covers connector condition, host identification, error-free link establishment and optical link operation, receive activity and diagnostic readouts. Providing the exact host model and firmware release helps us identify platform-specific requirements before production.

This product is ordered as CBL-QSFP-4 x 10G-AOC25M in 25m (82ft). 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.

Before packing, our team checks the cable jacket, connector boots, latches and identification of each assembly. The cable is then secured in a loose coil and protected against dust and connector impact. Neutral packaging, customer part-number labels and project-specific carton lists can be supplied on request.

Available stock is usually packed and handed to the carrier within one to three working days. Delivery can be arranged by international express, air cargo or sea freight, with tracking details supplied after dispatch. Freight-collect shipments and delivery to a customer warehouse or forwarder can also be coordinated.
