High-fibre-count links between main, horizontal and zone distribution areas.
MTP/MPO links selected for the transceiver, cassette or panel interface.
Structured cabling paths supporting staged 10G, 40G and 100G deployment.
Specify fibre count, MTP/MPO gender, polarity and overall length. The drawing shows the connector, boot, serial label and cable jacket.

The single-cable construction is 3.0 mm. Larger bundled assemblies use the following trunk diameters; confirm the selected construction with the order.
| Bundles | MTP/MPO-12 fibre count | MTP/MPO-24 fibre count | Trunk diameter |
|---|---|---|---|
| 2 | 24 | 48 | 7.2 mm |
| 3 | 36 | 72 | 9.3 mm |
| 4 | 48 | 96 | 9.5 mm |
| 6 | 72 | 144 | 11.7 mm |
| 8 | 96 | — | 12.01 mm |
| 12 | 144 | — | 17.3 mm |
Match fibre grade, connector gender, alignment pins and Type A, B or C polarity across the full link. A trunk connects multi-fibre interfaces; a breakout distributes fibres to individual connector legs.

Inspect the full multi-fibre end face, clean with an appropriate MTP/MPO cleaner and verify the pin arrangement before insertion. Keep the connector key aligned with the receiving port.

Confirm the cassette polarity and the matching connector gender before connecting the trunk.
Compare fibre grades and optical interfaces from 1G to 100G. These are link-planning references; cable length alone does not determine supported reach.

Use the exact transceiver specification, fibre bandwidth, connector loss and installation conditions to confirm the link. BiDi, SWDM4 and extended-reach results depend on the selected module. Parallel optics also require the correct fibre count and polarity.
Specify fibre grade and count, MTP/MPO gender, polarity, connector ends, jacket, overall length, any fan-out length and quantity.
Supported reach depends on the transceiver interface, fibre bandwidth, installed-link loss and application. Use the comparison table for initial selection, then check the exact transceiver specification.
Match Type A, B or C polarity, connector gender and key orientation to the transceiver, cassette and patching design. Verify the whole link before ordering.
Include the selected configuration and required inspection records in your enquiry. The applicable test scope and document format are confirmed for that assembly.
Send the connector ends, fibre grade, length, jacket, quantity and any polarity, labelling or inspection requirements.
