## Abstract

An antiviral optical tap system for a fiber optic circuit that uses an Optical Circulator or an Isolator or any other unidirectional optical device that is connected to the secondary optical tap output of an optical tap that prevents unwanted optical signals or optical noise from entering a fiber optic circuit through the secondary optical tap output and allows optical signals to pass to an external device through the Optical Circulator or Isolator or any other unidirectional device.

## Claims

### Claim 1

An optical tap system that consists of an optical tap, an optical circulator, an Isolator or any other unidirectional optical signal device where the optical tap Secondary Output is connected to an Optical Circulator or Isolator or any other unidirectional device and blocks optical signals from entering the optical tap Secondary Output from an external source and allows optical signals to pass to an external device through the Optical Circulator or Isolator or any other unidirectional device.

### Claim 2

An optical tap system that consists of an Optical Circulator, an Isolator or any other unidirectional optical device that is connected to the Secondary Output of an existing optical tap that blocks optical signals from entering the optical tap from an external source and allows optical signals to pass to an external device through the Optical Circulator or Isolator or any other unidirectional device.
