Fibre questions, clearly answered

Cable blowing uses a controlled machine feed and compressed air to install a compatible fibre optic cable through a prepared duct. It is also called cable jetting. The air and feed work together; the method relies on the duct system already being in place.

Blowing installs cable through an existing suitable duct. If a new pathway, repairs or extra access points are needed, those civil works are a separate part of the overall project. We confirm the route and responsibilities before the installation.

There is no single distance that applies to every job. Cable properties, duct size and condition, bends, route profile and air supply influence the result. A route may need staged installation. Give Hayden the actual route information rather than relying on a generic distance claim.

Possibly, but its presence does not prove it is suitable. We need to understand the duct type, size, route, continuity and condition, as well as any existing services inside it. Access and the cable-to-duct match also matter.

The right choice depends on the network design, link length, intended equipment and application. It must also match the rest of the system. Bring the equipment requirements or design specification so the fibre and termination details can be checked together.

A splice joins two fibre ends. A termination provides a connector interface for patching or equipment connection. One common termination method is to fusion splice an installed fibre to a factory-terminated pigtail.

Yes. Light Logic’s scope includes fibre splicing and termination work. Tell us the fibre type, connector format, polish type and panel or enclosure arrangement so the correct materials and method can be confirmed.

Do not directly mate APC and UPC end faces. They have different polish geometries, even when their connector bodies appear to fit the same adapter format. Confirm the complete connector and patching arrangement rather than matching the shape alone.

Talk to us about the proposed change, existing services, fibre records and access arrangements. Fibre ownership and service impact need to be established, with an agreed work method and outage window where required. Unknown fibres should not be disconnected on assumption.

They connect each cable and core to the correct splice, panel port and test result. Clear records help when a network is patched, fault-found or extended later. Agree the labelling and handover requirements before work starts.

An optical time-domain reflectometer sends pulses of light into a fibre and analyses returning light to help locate and characterise events. It can assist with finding breaks, unexpected loss and reflective connections. The trace needs to be interpreted with the link layout and test settings in mind.

No. A light source and power meter or loss test set measure insertion loss through the completed path. An OTDR provides a distance-based view of events along it. They answer different questions and can be complementary parts of the agreed test plan.

A splicer’s estimated loss is useful during the splice process, but it is not a substitute for testing the completed link. Connectors, other splices and the installed cable also contribute to its performance.

It can help estimate the distance to an event along the fibre. Slack loops, the internal fibre path, instrument settings and the accuracy of route records affect how that distance maps to the physical ground route. Further tracing or inspection may be needed before excavation is considered.

Note the symptoms, when they started, which links are affected and any recent changes. Gather route drawings, port schedules and previous test results if available. Avoid disturbing unfamiliar fibres or repeatedly changing patching without a record of what was connected.

Start with the site location, purpose of the link, end points, approximate length, available pathways, fibre count and the connection work required. Photos and drawings help. For existing links, include service and access constraints.

Call Hayden with the location, scope and required timing. Project suitability, travel and availability are confirmed directly for each enquiry.

Call to discuss what is known. The scope depends on route condition, access, cable and termination details, testing and any related works. A useful quotation needs the relevant requirements and assumptions to be clear.
