To connect among many radio base stations by using optical fiber bus link in microcellular system, subcarrier multiplexing (SCM) is excellent in simplicity and flexibility. But performance degradation due to optical beat noises is severe problem. To solve this problems, this paper proposes a new type of intercell connection bus fiber-optic link (ICBL) using time division multiplexing, called TDM-ICBL. This paper also analyzes transmission performance of TDM-ICBL theoretically and compares with SCM-ICBL. The analysis clarifies that while the number of RBSs connected to SCM-ICBL is severely restricted by beat noises, TDM-ICBL is more useful than SCM-ICBL when there are many number of connected RBSs.
