Cable Lens

Photograph the print on a fibre or copper cable and get a cable card: type, fibre count, colour code, termination, bend radius, fire class and how to test it. Every line says whether it was read from the print or comes from the standard.

The photo goes to an AI service (Groq, in the US) only to read the printed text. It is not stored, and location data is stripped on your phone before upload. Everything on the card is worked out in your browser from fixed tables.

The print, as readCorrect anything the reader got wrong; the card follows as you type.

Point the camera at the print on the jacket.

You get the fibre or copper type, the colour code, how to terminate it, the bend radius, the fire class decoded and how to test it. Each line says whether it was read from the print or comes from the standard.

How it works

Rules and tables you can check.

  • The AI only reads

    The photo is transcribed to text and nothing else. The model is never asked what the cable is, so it cannot invent a fibre type or a fire class.

  • Rules turn text into facts

    A fixed parser finds the markings, then the TIA, ISO and EN tables fill the card. Anything not on the print is marked to check on the datasheet.

  • It tells you when to retake

    Too few markings, a print cut off at the edge, or two markings that contradict each other: the card says so and asks for the next print along the cable.

  • Private by design

    The photo is shrunk and stripped of location data on your phone, read once, and not stored.

Straight answers

What engineers ask.

How do I identify a fibre optic cable?

Read the jacket print. It normally carries the maker, the fibre type (OS2 for single-mode, OM3, OM4 or OM5 for multimode), the fibre count (24F, 144F), the construction, the sheath (LSZH) and the CPR fire class. Jacket colour is a convention, not proof: yellow is single-mode, aqua OM3/OM4, lime OM5, orange OM1/OM2.

What does Cca-s1b,d1,a1 mean on a cable?

It is the EN 50575 reaction-to-fire class. Cca is the fire class (limited contribution to fire), s1b is low smoke with 60 to 80 % light transmittance, d1 means flaming droplets that go out quickly, a1 is the lowest acidity. In the UK, BS 6701 sets Eca as the minimum for telecom cable in buildings; data-centre specs often ask for Cca or better.

What is the difference between U/FTP and F/UTP?

The letter before the slash is the overall screen, the letters before TP are the pair screen. U/FTP has foil round each pair and no overall screen. F/UTP has one overall foil and unscreened pairs. Both are screened cable: bond them at the panel.

Is the photo stored?

No. It is shrunk and stripped of location data on your phone, sent once to an AI service (Groq, in the US) to read the text, and not kept. The card is worked out in your browser.

Need the engineers too?

GO2DataWorks puts cabling and fibre engineers on data-centre sites, or takes the whole package: installed, terminated, tested and handed over.
