CA 2153220

A fiber-optic access system for subscriber optical communi- cation adopting star type topology in an optical fiber network includes a central office, a plurality of optical network units, an optical interface, and a signal recogni- tion/reproduction and clock extraction IC. The optical interface is provided in the central office and includes an array optical transmission module as a package unit accom- modating a plurality of light sources and a plurality of output fiber terminals, and an array optical reception module as a package unit accommodating a plurality of optical sensors and a plurality of input fiber terminals. The signal recognition/reproduction and clock extraction IC is provided to each channel of the array optical reception module. The access system provided is of a scale compara- ble to that of a central office side optical interface of PDS and wide band characteristics comparable to those of a single star type system.
