Abstract
An optical trunk switch supporting an Optical Time-Domain Reflectometer (OTDR) includes a transmit switch configured to provide an input signal to one or more of a primary fiber path and a standby fiber path; a receive switch configured to provide an output signal from one of the primary fiber path and the standby fiber path; and an OTDR port configured to interface OTDR signals to monitor the standby fiber path.

An optical trunk switch supporting an Optical Time-Domain Reflectometer (OTDR), the optical trunk switch comprising:
- a transmit switch configured to provide an input signal to one or more of a primary fiber path and a standby fiber path;
- a receive switch configured to provide an output signal from one of the primary fiber path and the standby fiber path;
- and
- an OTDR port configured to interface OTDR signals to monitor the standby fiber path.
An optical trunk switch supporting an Optical Time-Domain Reflectometer (OTDR), the optical trunk switch comprising:
- a transmit 2×2 switch with a first input connected to a signal input, a second input connected to a first output of a 1×2 switch that is connected to an OTDR port, a third output connected to a first active fiber, and a fourth output connected to a first inactive fiber;
- and
- a receive 2×2 switch with a first output connected to a signal output, a second output connected to a second output of the 1×2 switch that is connected to the OTDR port, a third input connected to a second active fiber, and a fourth input connected to a second inactive fiber.
A method for providing an optical trunk switch supporting an Optical Time-Domain Reflectometer (OTDR), the method comprising:
- providing the optical trunk switch that includes
- a transmit switch configured to provide an input signal to one or more of a primary fiber path and a standby fiber path;
- a receive switch configured to provide an output signal from one of the primary fiber path and the standby fiber path;
- and
- an OTDR port configured to interface OTDR signals to monitor the standby fiber path.
