Burst mode optical receiver using two amplifiers having different bandwidth |
摘要 |
A burst mode optical receiver using two amplifiers having different bandwidth. The receiver includes an optical coupler separating an input optical signal into two parts and outputting the same, a delay circuit formed of a first optical fiber delaying an optical signal packet outputted through the optical coupler by a half of packet duration and a second optical fiber passing the optical signal packet without delay, and a first pre-amplifier having a high bandwidth for receiving an optical signal from the first optical fiber and amplifying the same and a second pre-amplifier having a low bandwidth for receiving an optical signal from the second optical fiber and amplifying the same, for thereby improving a receiving sensitivity without using a preamble bit.
