摘要： An optical module includes a module body on which at least one photo diode is mounted, a filter holder inserted into the module body, and a thin film filter mounted on the filter holder in order to guide optical signals towards photo diodes in such a manner that optical signals with corresponding wavelengths are received in the photo diodes. The filter holder, on which the thin film filters are mounted, is fabricated separately from the module body and houses active elements, such as the laser diode and photo diodes. The filter holder is inserted into the module body thereafter, so the optical module is easily fabricated at a low cost and in a simple manner.

摘要： Disclosed is an optical receiver for receiving burst mode signals. In a first embodiment, AGC voltage is applied to a continuous mode TIA having an AGC function, so that the AGC function is stopped and a gain of the TIA is fixed to a constant. In a second embodiment, a continuous mode TIA capable of adjusting an AGC time by using an external condenser is used. Accordingly, the TIA commonly used in a continuous mode is utilized in a burst mode operation, so that the construction of the optical receiver can be simplified and cost can be saved.
