I maggiori problemi che sorgono dalle reti in fibra ottica sono i problemi con il loro collegamento. Questo è il motivo per cui cerchiamo metodi efficienti che ci aiutino a risolvere meglio le aree problematiche nei cavi. Uno di questi prodotti è un Visual Fault Locator.

Un localizzatore visivo di guasti è una parte molto importante del kit di installazione e manutenzione dei cavi in fibra ottica. Può aiutarci a identificare rotture, piegature o usura della fibra di vetro utilizzata nei cavi in fibra ottica monomodale o multimodale. La luce utilizzata nei cavi in fibra ottica è la luce infrarossa, quindi è impossibile vedere dove si verificano le perdite nei cavi ad occhio nudo. È qui che entrano in gioco i VFL poiché utilizzano la luce di una potente sorgente laser che possiamo usare per vedere dove si verificano le perdite elevate in un cavo in fibra ottica.

Tester di continuità della fibra contro VFL

La principale differenza tra i tester di continuità delle fibre e i localizzatori visivi di guasti è il tipo di sorgente luminosa che utilizzano. I tester di continuità della fibra utilizzano LED visibili (principalmente rossi o verdi) mentre i localizzatori di guasti visivi utilizzano un diodo laser rosso ad alta potenza (635-670 nm). I tester di continuità della fibra sono i più basilari in quanto possono solo aiutarci a scoprire se c’è un problema con la fibra identificando se la luce passerà o meno attraverso l’intero cavo. Se la luce passa attraverso i cavi funziona bene, altrimenti richiede un’analisi più dettagliata.

Considerando che i VFL ci forniscono un’analisi più dettagliata aiutandoci a individuare la posizione esatta in cui si verificano le perdite a causa di cattive connessioni o curve, e non dobbiamo preoccuparci di nessun’altra apparecchiatura per un’ulteriore diagnosi.

Il principio su cui funzionano i localizzatori visivi di guasti

Un diodo laser rosso ad alta potenza viene utilizzato per inviare luce attraverso il nucleo del cavo in fibra ottica che può viaggiare per una certa distanza e aiutarci a tracciare la luce mentre passa attraverso i cavi e individuare eventuali perdite elevate in essi. I VFL hanno un’applicazione principale per cavi a breve distanza che vanno fino a pochi chilometri ed è per questo che possono essere utilizzati come parte di OTDR nelle regioni delle zone morte OTDR.

Tipi di localizzatori visivi di guasti

I localizzatori di guasti visivi sono disponibili in diverse forme e dimensioni. Esistono due tipi in base a come funzionano, vale a dire contatto e senza contatto. Nel caso di un VFL a contatto, la fibra ottica che stiamo testando entra in contatto fisico diretto con il VFL e nel caso di un VFL senza contatto, la fibra ottica che stiamo testando non entra in contatto diretto con il VFL. Per scopi commerciali, esistono 3 tipi principali di localizzatori visivi di guasto:

Localizzatore visivo di guasti a forma di penna: è tascabile e può essere portato facilmente in giro. Questo è un tipo di contatto VFL.

Localizzatore di guasti visivo portatile: questo è un tipo di contatto VFL ed è disponibile in diversi tipi di connettori, che vanno da tipi di connettori specifici a universali.

Localizzatore di guasti in fibra ottica portatile: si tratta di un VFL senza contatto e viene utilizzato per identificare guasti e perdite nei cavi in fibra ottica, in particolare nei cavi a corto raggio come LAN, ATM, FDDI e reti di telecomunicazione.

Parametri importanti dei VFL

Alcuni parametri importanti in base ai quali è possibile misurare le prestazioni VFL che sono:

Potenza in uscita: la potenza in uscita è un fattore molto importante per le prestazioni VFL. I VFL possono funzionare per distanze maggiori con una maggiore potenza di uscita.

Distanza in fibra – Questa è la distanza massima nei cavi in fibra ottica fino alla quale possiamo vedere perdite o aree problematiche senza troppi problemi. Questo è determinato dalla potenza del diodo laser. I VFL normali hanno una portata di 5 km per fibre monomodali industriali e una portata di 10 km per fibre multimodali.

Lunghezza d’onda: la lunghezza d’onda dei VFL funziona perfettamente nell’intervallo 635 nm – 670 nm.

Frequenza di modulazione: l’occhio è in grado di captare meglio una luce lampeggiante, motivo per cui i tecnici preferiscono i VFL con una luce lampeggiante piuttosto che fissa poiché li aiuta a diagnosticare meglio i difetti nei cavi.

Hai imparato tutto ciò di cui hai bisogno sui localizzatori visivi di guasti?

Un localizzatore visivo di guasti è uno strumento ideale per l’installazione, il collaudo e la manutenzione di cavi in fibra ottica perché può essere utilizzato per individuare molti difetti che possono verificarsi nei cavi in fibra ottica come rotture, crepe o piegature in regioni con giunzioni di fusione scadenti. Poiché la luce che passa attraverso i cavi in fibra ottica è a infrarossi, un localizzatore visivo di guasti è un ottimo strumento per aiutarci a vedere le aree che necessitano di miglioramento attraverso i nostri occhi. Un VFL inizia il suo processo emettendo luce tramite un potente laser rosso attraverso il nucleo del cavo in fibra ottica. Quando la luce passa attraverso il cavo, illumina la regione che circonda il cavo (buffer) nelle regioni in cui sono presenti anomalie come rotture, crepe o piegature del connettore, dovute all’irraggiamento della luce rossa visibile. Questo può funzionare perfettamente se utilizzato come parte di un OTDR poiché gli OTDR hanno alcuni punti ciechi o zone morte durante i quali non otteniamo letture e poiché i VFL possono aiutarci a vedere dove sono i nostri difetti, questo risolve molti problemi. L’utilizzo di VFL può rivelarsi molto utile e aumentare la produttività perché è professionale
