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.

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

Choose QSFP+ to 4 duplex LC-40G-AOC-20M66FT when the measured managed path justifies 20m (66ft), not simply to leave a large spare coil. Additional reach can simplify adjacent-rack routing, yet unused cable still needs bend-safe storage and ventilation clearance. Keep identification visible so this extended version is not confused with shorter spares. Within this family, QSFP+ to 4 duplex LC-40G-AOC-15M49FT is shorter at 15m (49ft), while QSFP+ to 4 duplex LC-40G-AOC-30M98FT is the next longer choice at 30m (98ft); comparing those two boundaries helps avoid both tension and unnecessary slack.

Position Within the Length Range

QSFP+ to 4 duplex LC-40G-AOC-20M66FT occupies the middle of this family between QSFP+ to 4 duplex LC-40G-AOC-15M49FT at 15m (49ft) and QSFP+ to 4 duplex LC-40G-AOC-30M98FT at 30m (98ft). It adds 5m over the shorter option for extra routing clearance, while the next longer version adds another 10m. 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.

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.

Breakout Port Mapping

The QSFP+ to 4 duplex LC 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.

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. Volume orders can include customer references on the labels and carton list.

Generic 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. The check includes receive activity and diagnostic indications, followed by a final inspection of both ends.

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 QSFP+ to 4 duplex LC-40G-AOC-20M66FT associated with 20m (66ft) throughout the order and receiving record.

Shipping and Lead Time

Available stock is generally dispatched within one to three working days after order confirmation, with production lead times advised for larger quantities. Delivery can be arranged by courier, air freight or sea freight, and goods may instead be handed to an appointed forwarder or shipped on the customer’s courier account.
