Radiantech’s Visual Fault Locator is equipped with a 650 nm high power visible laser diode, which can be operated in CW (continuous) or MOD (1 Hz modulation) mode. There are two LED indicators, RED and GREEN: The RED one shows the operating mode of the Laser Diode output signal, and the GREEN one indicates low battery level. FFL-200 series are housed in a pocket-size, rugged brass casing, and comes with a carrying pouch while FFL-300 series are in a card-style compact design.
Features
High power 650 nm laser
Shock-proof casing
Slim, pocket sized, pen-type or card-size design
Continuous or 1 Hz modulated outputs
SM/MM compatible
Longer than 40 hours continuous operation, 80 hours for modulation mode
Measurement range up to 8 km. (FFL-210 and FFL-310)
Caution: Output optical power is hazardous and may cause permanent damage to eyes. Do not look into the universal receptacle or the fiber when the unit is on. Close the protective lid when not in use to avoid unexpected exposure and keep the receptacle clean.
