Atenuator variabil optic TW3303 TW3303 este un atenuator optic variabil de mana, utilizat pentru atenuarea continua variabila a semnalului optic. Deoarece atenuatorul este utilizat în sistem laser pentru testarea on-line, TW3303 poate fi utilizat în sisteme digitale de dispozitive comunicare (cum ar fi: PHD, SDH) si de asemenea, în sistemele de adoptare a modularii analogice (CATV). ---------------------------------------------------------------------------------------------------------------------------------------- Optical Variable Attenuator TW3303 TW3303 handhold optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, there, thereforeTW3303 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)
