Expanded single fiber combining module

Abstract

A system may use a single fiber combining module (SFCM) that combines multiple wavelength channels of different optical technologies over a single fiber. In an example, a SFCM may include a original band (O-band) port, wherein the O-band passes signals at a first wavelength range; a XGS PON port, wherein the XGS-PON port passes signals at a second wavelength range; a dense wavelength division multiplexing (DWDM) port, wherein the DWDM port passes signals at a third wavelength range, wherein the first frequency range, the second frequency range, and the third wavelength range are different; and a common port connected with a fiber, the common port simultaneously combining signals from the O-band port, XGS-PON port, and the DWDM port.
