Frequently asked questions

For a single office floor with around 50 ports and pathways already in place, usually one to two weeks. In an occupied building, or where new pathways are needed, it takes longer. We give a precise schedule after the site survey, together with the quotation.

No. The site survey and the initial estimate are free. Charges begin at detailed design and drawing production — and even that is deducted from the total if you go ahead with the installation.

We cover the performance of the passive system for ten years: if a link falls below the standard’s limits in that time, putting it right is on us. The conditions are the technical ones — the whole channel built from compatible components, and the full test report handed over at completion, which is the baseline any later measurement is compared against.

Both. Many projects start with design and a bill of quantities, and the client decides on the installation later. Design can also be commissioned on its own.

Yes. We deliver industrial and multi-building projects across Iran. For small projects outside Tehran and Alborz there is usually a minimum size that makes the trip worthwhile for both sides.

Yes. Our team is made up of both passive and active specialists, and without both of them in the room the design is never quite right. We are with you from sourcing every single port through to installing and bringing up the cluster on your server. Where a client wants it, we also stay on for ongoing active and passive support.

The cost per port depends on the cable category, the average run length, the type of pathway (tray, trunking or floor boxes) and the condition of the building. In an office building with pathways already in place, the cost per port is considerably lower than the same job in an occupied, operating building. We give an itemised estimate after the site survey.

Yes. Every port gets a Permanent Link test on a calibrated tester, and the full report is delivered as a file you can hand to the client and the supervising engineer. Any link without an adequate margin is corrected before handover.

In an ordinary office environment, usually not. In an industrial environment, close to power lines, or in dense Cat6A installations with high-power PoE, screened cable (S/FTP or F/FTP) is recommended — provided the screen is properly bonded to earth, because without that it does more harm than good.

In a fusion splice the two fibre ends are melted into one by an electric arc; loss is typically under 0.1 dB and the joint is permanent and stable. A mechanical splice is faster and cheaper but has higher loss and is less stable over time. For a backbone we always recommend fusion.

A power meter only tells you the total loss of the path. An OTDR gives you a map of it: every splice, every connector, every excess bend, and the exact position of each event in metres. If the path ever breaks, that original trace locates the fault quickly.

If you have few units and limited room space, a wall-mounted rack is enough. But if you have more than two patch panels, several switches and a UPS, or if growth is likely, a floor-standing rack gives you better access and much more controllable ventilation.

No. Sharing a pathway with power lines is not permitted by the standards, and in practice it causes noise and degrades link quality. The data route must be separate, and where a crossing is unavoidable it should cross the power route at right angles.

Three things: it is the basis for handover and final payment, it is the condition for activating the cable manufacturer’s system warranty, and it is the reference for future fault-finding — when a port misbehaves three years later, comparing it against day-one figures immediately tells you whether the problem is the infrastructure or the equipment.

It is corrected and retested. A port that has failed is not handed over. The usual causes are poor termination, a tight bend, and physical damage during pulling.

That every infrastructure component has a unique, readable identifier, and that this identifier is the same across all documentation — on the port, on the outlet, in the drawings and in the test report. The result is that anyone, years later, can trace a port without having to call the original installer.
