Before the apparition of the optical amplifiers, one of the traditional problems of the use of bus structures in the optical passive networks was the limited number of nodes could be supported. In this work, a passive optical network is presented where conventional data can share the same optical fiber with data from sensors of temperature, luminosity, humidity, etc. A double amplified recirculating ring structure is used not only for amplifying but for equalizing and filtering the signals coming from optoelectronics units attached to fiber couplers carrying the sensors information.
