Abstract
A coexistence element within a passive optical network (PON) includes a housing having a plurality of input communication ports. Each input communication port is configured to receive, via a separate optical fiber, optical communications each having a wavelength within a particular wavelength band corresponding to a particular optical service. At least one of the input communication ports is configured to receive optical communications having wavelengths within two or more different wavelength bands. The housing also includes an output communication port configured to transmit, via a single optical fiber, the optical communications from each of the plurality of input communication ports.
Claims25
A coexistence element within a passive optical network (PON) comprising:
- a housing including:
- a plurality of input communication ports each configured to receive, via a separate optical fiber, optical communications each having a wavelength within a particular wavelength band corresponding to a particular optical service, wherein at least one of the plurality of input communication ports is configured to at least one of:
- (i) receive optical communications having wavelengths within two or more different downstream wavelength bands or (ii) receive optical communications having wavelengths within the same wavelength band which correspond to different optical services;
- and
- an output communication port configured to transmit, via a single optical fiber, the optical communications from each of the plurality of input communication ports.
A method for wavelength division multiplexing, comprising:
- receiving, at each of a plurality of input communication ports within a coexistence element in a passive optical network (PON) via a separate optical fiber, optical communications each having a wavelength within a particular wavelength band corresponding to a particular optical service, wherein at least one of the plurality of input communication ports receives optical communications having wavelengths within two or more different downstream wavelength bands or receives optical communications having wavelengths within the same wavelength band which correspond to different optical services;
- combining, by the coexistence element, the plurality of optical communications;
- and
- transmitting, by an output communication port within the coexistence element, the combined optical communication via a single optical fiber.
