Specifications

Cable Construction and Routing

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.

Network and Protocol Considerations

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.

Integrated Optical Assembly

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.

Length Selection and Installation Planning

At 20m (66ft), (Force10) CBL-QSFP-40GE-20M should be planned as an extended equipment-room connection rather than a short in-rack jumper. Mark the complete vertical and horizontal route before installation, including every manager the cable will actually pass through. Support the integrated optical cable and both optical engines along that path and keep both ends free from pull loads. Within this family, (Force10) CBL-QSFP-40GE-15M is shorter at 15m (49ft), while (Force10) CBL-QSFP-40GE-25M is the next longer choice at 25m (82ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

(Force10) CBL-QSFP-40GE-20M occupies the middle of this family between (Force10) CBL-QSFP-40GE-15M at 15m (49ft) and (Force10) CBL-QSFP-40GE-25M at 25m (82ft). 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.

Rack Layout and Service Access

Plan the managed route before removing the connector protection. The cable should reach both ports without tension while leaving enough space to release the latches and service adjacent interfaces. Support the run through the intended managers, keep the connector boots clear of sharp edges and avoid storing excess length in a tight coil behind warm exhaust air. For this assembly, the minimum bend radius is 30mm; the jacket material is OFNP.

Quality Assurance and Packaging

The completed cable is inspected at both ends, functionally tested and coiled with bend-safe slack. Protective packaging keeps the latches and boots from taking impact, while optional project labels can identify the two endpoint locations for easier field service. Standard protective packing is used by default, with project documentation arranged when requested.

Dell Compatibility and Factory Testing

Compatibility is verified as part of a complete installation check: connector inspection, host identification and an operating link. The physical cable is evaluated together with the expected OEM identity, because a connector that fits is not sufficient evidence that the host will accept and operate the assembly correctly. Both connectors are examined before the operating test, which includes receive activity and diagnostic indications.

Frequently Asked Questions

Ordering Information

When requesting this assembly, include the exact part number and length together with the destination port types. For a rack installation, a simple port-to-port list helps us keep different lengths separate and allows any requested labels to correspond with the actual installation sequence. Keep (Force10) CBL-QSFP-40GE-20M associated with 20m (66ft) throughout the order and receiving record.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, while production quantities are confirmed with the order. International express, air cargo and sea freight can be selected according to destination and carton volume; customer courier accounts and nominated forwarders are also accepted.
