Abstract
Optical equipment for 1G-EPON, 10G-EPON, and CWDM services are joined together using a novel combination of optical power splitters and multiplexers. This combination of splitters and multiplexers can be disposed in a single housing, which reduces the size of the combination and improves performance, since jumpers between multiple, separately packaged, optical components can be avoided. One example of the inventive techniques and circuits disclosed herein is a combiner/separator circuit for combining and separating 1G-EPON and 10G-EPON signals. In the example application detailed herein, where EPON equipment is combined with CWDM equipment, an important advantage of this optical circuit is its ability to provide return wavelength isolation for EPON systems that have separate ports for 1G and 10G services.
