Fiber Optic Attenuators provide technicians with a means of adjusting an optical signal level. Applications include field and laboratory testing of system performance over a range of attenuation values (optical path lengths) and tuning and verifying performance of new transmitters to specific networks at time of installation. AFL offers a range of attenuators providing test options to technicians.
