Abstract
Single transceiver modules are provided at each end of a single communication link such that the need for redundant links is reduced or eliminated. Modules of the invention provide full assurance against disruption of communication due to fiber breakdown, and certain forms of equipment failure, such as the failure of a single receiver. Modules of the invention include multiple reception and transmission ports, and can be applied to any communication link, and require that redundant data be sent by two separate transceivers via two separate fibers. Devices and methods are provided which reduce, or eliminate the need for “client side 1+1 protection.”

A fiber-optic transceiver module comprising
- A fiber-optic transmitter;
- A first fiber-optic receiver;
- A second fiber-optic receiver;
- A digital multiplexer;
- A controller to control the multiplexer.
A fiber-optic transceiver module comprising
- A fiber-optic transmitter;
- A fiber-optic power splitter
- A first fiber-optic receiver;
- A second fiber-optic receiver;
- A digital multiplexer;
- A controller to control the multiplexer.
A fiber-optic transceiver module comprising
- A first fiber-optic transmitter;
- A second fiber-optic transmitter;
- A first fiber-optic receiver;
- A second fiber-optic receiver;
- A digital multiplexer;
- A controller to control the multiplexer.
A fully redundant fiber-optic communication link wherein the failure of a transceiver, or a repeater or any other intermediary component on one of the two redundant communication channels does not cause interruption of communication, allowing uninterrupted communication through the alternate communication channel.
