| | Using optical fiber multiplexer to combine light beams in a laser printer - Patent 5666447 |
 | | a second optical fiber multiplexer having a first input port connected to said second output of said first optical fiber multiplexer and its second input port connected to one of said laser light sources, and a pair of output ports having said first and second wavelengths of light. |
 | | Fiber multiplexers used in the optical communication are either not able to provide efficient use of optical power provided by the light sources or not matched to the media photosensitivities. |
 | | In each optical fiber multiplexer, part of the light will be coupled out to the other fiber, the more optical fiber multiplexers it passes through, the more light will be coupled out and the greater the loss incurred by the optical fiber multiplexer. |
