Attenuators are used to adapt the transmitted light power to the characteristics of the implanted receiver. The Telegärtner SC and LC singlemode inline attenuator brings together the benefits of an attenuation performed using special doped fiber and the innovative features of the SC and LC connector system. Different insertion loss values are achieved using specially doped fibers, thus ensuring availability over the full range of wavelengths from 1250 to 1360 nm and 1480 to 1580 nm. The standard product range includes attenuators in 5 dB and 10 dB, max. 30 dB with 1 dB increments are also available on request. Telegärtner attenuators are characterized by low tolerance, constant attenuation values over the entire service life, a robust design with metal housing and by simple, economic handling.
