Abstract
A high capacity node includes a plurality of transceivers each with a transmitter configured to support a wavelength within a full transparent window of one or more optical fibers; and one or more optical amplifiers covering the full transparent window, wherein the one or more optical amplifiers comprise one of (i) a single ultra-wideband amplifier covering the full transparent window and (ii) a plurality of amplifiers each supporting a different band of the full transparent window.
Claims18
A high capacity node, comprising:
- a plurality of transceivers each with a transmitter configured to support a wavelength within a full transparent window of one or more optical fibers;
- an electrical cross-point switch communicatively coupled to the plurality of transceivers, wherein the cross-point switch performs colorless, directionless, contentionless, and waveblockless functions equivalent to a Reconfigurable Optical Add-Drop Multiplexer (ROADM), wherein the cross-point switch is further communicatively coupled to one or more Time Division Multiplexing (TDM) or packet switches which perform sub-wavelength layer traffic grooming and the cross-point switch performs wavelength layer traffic grooming;
- and
- one or more optical amplifiers covering the full transparent window, wherein the one or more optical amplifiers comprise one of (i) a single ultra-wideband amplifier covering the full transparent window and (ii) a plurality of amplifiers each supporting a different band of the full transparent window.
A high capacity node, comprising:
- a plurality of transceivers each with a transmitter configured to support a wavelength within a full transparent window of one or more optical fibers;
- a cross-point switch communicatively coupled to the plurality of transceivers, wherein the cross-point switch is communicatively coupled to one or more Time Division Multiplexing (TDM) or packet switches, wherein the cross-point switch is configured to perform wavelength layer traffic grooming and the one or more TDM or packet switches are configured to perform sub-wavelength layer traffic grooming;
- and
- one or more optical amplifiers covering the full transparent window, wherein the one or more optical amplifiers comprise one of (i) a single ultra-wideband amplifier covering the full transparent window and (ii) a plurality of amplifiers each supporting a different band of the full transparent window.
A method implemented in a high capacity node, comprising:
- operating a plurality of transceivers each with a transmitter configured to support a wavelength within a full transparent window of one or more optical fibers;
- providing outputs from the plurality of transceivers to a cross-point switch communicatively coupled to the plurality of transceivers;
- utilizing the cross-point switch to perform wavelength layer traffic grooming and one or more TDM or packet switches connected to the cross-point switch to perform sub-wavelength layer traffic grooming;
- and
- operating one or more optical amplifiers covering the full transparent window to amplify optical signals associated with the plurality of transceivers, wherein the one or more optical amplifiers comprise one of (i) a single ultra-wideband amplifier covering the full transparent window and (ii) a plurality of amplifiers each supporting a different band of the full transparent window.
