Abstract :
Five kinds of modulation code for fiber optic network are analyzed. They are bilevel Manchester, trilevel Manchester, pulse position modulation (PPM) Manchester, pulse frequency keying (PFK) and the partial trilevel Manchester code. The modified Personick (1973) formulas for the special cases are derived. With these formulas we calculate the sensitivities of optical receiver with configurations of PIN-FET, PIN-BJT, APD-FET and APD-BJT. Other practical characteristics are also analyzed. Although each modulation code has its advantages and disadvantages, PPM, bilevel Manchester and PFK are better modulation codes for fiber optic networks
