Abstract:
1. An optical line terminating apparatus which is star-connected to a first optical network terminating unit and a second optical network terminating unit through an optical fiber and a splitter, the optical line terminating apparatus comprising: a fixed wavelength band optical receiver; an electric signal amplifier; an electric signal branch section; and a first clock and data recovery section, wherein the fixed wavelength band optical receiver receives optical signals having a same wavelength and mutually different bit rates from the first and second optical network terminating units and converts the optical signals into electric signals, wherein the electric signal amplifier amplifies the electric signals, wherein the electric signal branch section branches the amplified electric signals, and wherein the first clock and data recovery section extracts a first data signal and a first clock signal corresponding to a bit rate of the signal of the first optical network terminating unit from the branched signal.
