Noyes OFL280 Handheld FTTx OTDR

NOU: Acest model a fost inlocuit de OFL280 FlexTester

Modelul Noyes OFL280 produs de AFL Telecommunications este un OTDR (Optical Time Domain Reflectometer) pentru fibre single mode si vine in doua variante optimizate FTTx. Modelul pentru instalare si reparare poate opera la trei lungimi de unda (1310/1550/1625 nm) pe fibre fara semnal, dar se schimba automat intr-un mod filtrat pe 1625nm in momentul detectarii semnalului pe fibra. In plus, portul de test este echipat cu un PON power meter care permite detectarea de fibre FTTx cu semnal, masurarea nivelurilor de putere ale retelelor FTTx si localizarea problemelor pe retelele FTTx cu un singur OTDR conectat la retea si un singur test automat. Este disponibil si un model conventional cu trei lungimi de unda (1310/1550/1625 nm) care permite localizarea defectelor aparute pe retele fara semnal.

Ambele modele OFL280 pot functiona in mod Full Auto, Timp Real sau in modul Expert (manual) si ofera: analiza precisa a evenimentelor, optical power meter, sursa laser, durata de viata a bateriei de 12 ore, spatiu intern de stocare si conectivitate USB. Porturile OTDR si OPM sunt echipate cu adaptoare care nu necesita alte unelte pentru schimbare.

Rezultatele sunt salvate in format .SOR si pot fi transferate pe un PC pentru vizualizare, tiparire si analizare cu software-ul livrat in pachet, compatibil Windows.

Aplicatii:
• Testarea fibrelor fara semnal pentru trei lungimi de unda
• Testarea fibrelor cu semnal la 1625 nm
• Masurarea sudurilor, a conexiunilor si a pierderilor de la un capat la celalalt
• Masurarea reflectantei conectorilor
• Masurarea nivelurilor de putere pentru retele FTTX la 1490 si la 1550 nm
• Testare terminalelor si a patch panelurilor cu ajutorul VFL (visual fault locator)
• Localizarea indoirilor fibrei
• Capacitatea de urmarire a fibrelor de pana la 5 km cu ajutorul VFL
• Masurarea pierderii de la un capat la celalalt cu ajutorul OLS si OPM.
