Abstract
This paper describes operation, design and results of laboratory tests of optical fiber transmitter and receiver for 480 channel /34 Mbit/s, third level of European hierarchy/ PCM telephone system. These units are designed to operate with multimode graded index fiber on 880 nm wavelength. In transmitter the Siemens SFH 408-880 Ga Al As laser diode is used. The receiver employes the FTL type silicon fiber optic APD, featuring a sensitivity of -49.8 dBm for BER = 10-9 and a dynamic range of 31 dB. Repeater spacing may be as long as 12 km taking into account adequate margins, which is satisfactory for urban networks.
