Abstract

A fiber optic assembly is provided including a body defining a fiber routing volume, a plurality of fiber optic components disposed in a front side of the body, and a plurality of optical filters disposed within the volume. The plurality of optical filters enable at least twenty four (24) dense wavelength division multiplexing (DWDM) channels.

First claim

What is claimed is:

1. A fiber optic apparatus, comprising:
a chassis;
wherein the chassis is configured to support a fiber optic connection density of at least one hundred ninety-two (192) wavelength division multiplexing (WDM) channels per U space, based on using at least one duplex fiber optic component;
a plurality of fiber optic equipment trays supported by the chassis; and
a plurality of fiber optic assemblies configured to be installed in the plurality of fiber optic equipment trays, wherein each fiber optic assembly of the plurality of fiber optic assemblies comprises a front side configured to support the at least one duplex fiber optic component, a fiber routing volume, and a plurality of optical fibers disposed within the fiber routing volume and arranged to establish optical connections between an input fiber optic component and at least one output fiber optic component.

2. The fiber optic apparatus of claim 1 , wherein the chassis is configured to support a fiber optic connection density of at least two hundred eighty-eight (288) WDM channels per U space.

3. The fiber optic apparatus of claim 1 , wherein the chassis is configured to support a fiber optic connection density of at least three hundred sixty (360) WDM channels per U space.

4. The fiber optic apparatus of claim 1 , wherein the at least one duplex fiber optic component comprises at least one dual-ferrule very small form factor (VSFF) component.

5. The fiber optic apparatus of claim 1 , wherein the WDM channels are dense wavelength division multiplexing (DWMD) channels.

6. The fiber optic apparatus of claim 1 , wherein each fiber optic equipment tray of the plurality of fiber optic equipment trays is configured to receive multiple fiber optic assemblies of the plurality of fiber optic assemblies.

7. The fiber optic apparatus of claim 1 , wherein the at least one duplex fiber optic component comprises a plurality of dual-ferrule very small form factor (VSFF) adapters, wherein each dual ferrule VSFF adapter is configured to receive three (3) dual ferrule VSFF connectors.

8. The fiber optic apparatus of claim 7 , wherein the plurality of VSFF adapters comprises a plurality of MDC adapters.

9. The fiber optic apparatus of claim 8 , wherein the plurality of VSFF adapters comprises SN adapters.
