Patent number: 8290376Abstract: An optical receiver with a simplified arrangement able to compensate the optical loss of the transmission medium is disclosed. The optical receiver of the invention includes an SOA in the front end thereof, an optical de-multiplexer, and a plurality of receiver modules that receives de-multiplexed light. The optical gain of the SOA is adjusted based on the electrical signals output from respective optical modules. When the receiver modules show the output thereof in a preset range, the bias current is kept unchanged, while, one receiver module shows the output out of the range, the bias current is incremented or decremented. When one receiver module shows the output out of the absolute maximum/minimum, the bias current is forced to the initial value.Type: GrantFiled: March 16, 2011Date of Patent: October 16, 2012Assignee: Sumitomo Electric Industries, Ltd.Inventor: Hirotaka Oomori
