Abstract

Claims (30)

1 . An optical system comprising:

a plurality of first connectors configured for conveying optical signals;

a plurality of second connectors configured for conveying optical signals;

a first optical switch configured for conveying optical signals conveyed from one or both of the plurality of first connectors and the plurality of second connectors; and

a first component,

wherein the first optical switch is configured for selectively passing optical signals conveyed from the one or both of the plurality of first connectors and the plurality of second connectors to the first component.

2 . The optical system of claim 1 , further comprising an optical filter, wherein the first optical switch is configured for receiving optical signals conveyed from the one or both of the plurality of first connectors and the plurality of second connectors from the optical filter.

3 . The optical system of claim 2 , wherein the optical filter is a wavelength division multiplexing (WDM) or optical tap module.

4 . The optical system of claim 1 , further comprising:

an optical splitter or a second optical switch configured for conveying optical signals, the first component being in optical communication with one of the optical splitter and the second optical switch; and

a second component in optical communication with the one of the optical splitter and the second optical switch, wherein optical signals received by the one of the optical splitter and the second optical switch are i) filtered into a first portion conveyed to the first component and a second portion conveyed to the second component when the optical system comprises the optical splitter and ii) conveyed to either the first component or the second component when the optical system comprises the second optical switch.

5 . The optical system of claim 4 , wherein the optical splitter is a wavelength division multiplexing (WDM) unit.

6 . The optical system of claim 4 , wherein the first optical switch is configured to convey optical signals conveyed from only one of the plurality of first connectors to the optical splitter or from only one of the plurality of second connectors to the optical splitter.

7 . The optical system of claim 4 , wherein the first optical switch is configured to convey optical signals conveyed from more than one of the plurality of first connectors and the plurality of second connectors to the optical splitter.

8 . The optical system of claim 7 , wherein the optical splitter is configured for conveying optical signals conveyed from only one of the plurality of first connectors or from only one of the plurality of second connectors to the first component or to the second component.

9 . The optical system of claim 7 , further comprising first optical fibers extending between the first optical switch and the plurality of first connectors and second optical fibers extending between the first optical switch and the plurality of second connectors.

10 . The optical system of claim 4 , wherein each of the first component and the second component is a distributed acoustic sensing (DAS) module, an optical time-domain reflectometer (OTDR), an optical transmitter, or an optical receiver and the second component, and wherein the first component is different than the second component.

11 . The optical system of claim 1 , wherein the first optical switch is configured for switching optical signals being conveyed from a first connector of the plurality of first connectors to a second connector of the plurality of second connectors to being conveyed from the first connector to a third connector of the plurality of second connectors.

12 . An optical system comprising:

a first connector configured for conveying optical signals;

a second connector configured for conveying optical signals;

a first optical switch configured for conveying optical signals conveyed from one or both of the first connector and the second connector;

one of an optical splitter or a second optical switch configured for conveying optical signals;

a first component in optical communication with the one of the optical splitter or the second optical switch; and

a second component in optical communication with the one of the optical splitter or the second optical switch,

wherein the first optical switch is configured for selectively passing optical signals conveyed from the one or both of the first connector and the second connector to the one of the optical splitter or the second optical switch, and

wherein optical signals received by the one of the optical splitter or the second optical switch are i) filtered into a first portion conveyed to the first component and a second portion conveyed to the second component when the optical system comprises the optical splitter and ii) conveyed to either the first component or the second component when the optical system comprises the second optical switch.

13 . The optical system of claim 12 , further comprising an optical filter, wherein the first optical switch is configured for receiving optical signals conveyed from the one or both of the first connector and the second connector from the optical filter.

14 . The optical system of claim 13 , wherein the optical filter is a wavelength division multiplexing (WDM) or optical tap module.

15 . The optical system of claim 12 , wherein the optical splitter is a wavelength division multiplexing (WDM) unit.
