Optical Sleeve OS

OpticSleeve.jpg

It is intended for transmission of the signals of the frequency range of from 5MHz to 6000 MHz without loss. Laser emission intensity modulation is effected by the signal of the specified range (with a 100dB/µV level) (wavelength is 1310nm) with a further transformation back to electrical signal with the same level (100 dB/µV). Accuracy of electrical signal maintenance at the optical transmitter output is ±2dB when the optical sleeve and a measuring device LFM-500M operate together (in a radio-frequency mode or in an amplitude frequency characteristic measuring device mode). Depth of level control is 30dB, noise level is not worse than minus 90 dBc/Hz.
