Abstract:
Provided are an apparatus and a method for resetting a transimpedance amplifier for low-power passive optical network equipment for improving the synchronization performance of an uplink burst signal by resetting the transimpedance amplifier for amplifying a received signal of an optical transceiver at a time point at which a frame of the uplink burst signal ends. There is an effect of improving the burst-mode clock and data reconstruction performance through simple analysis of a bit pattern and thus reducing a guard time or a number of repetitions of preambles by accurately identifying the time point at which the frame of the uplink burst signal ends without using a frame data analysis scheme to reset the transimpedance amplifier.

Claim (Index 7):
An apparatus for resetting a transimpedance amplifier for low-power passive optical network equipment, the apparatus comprising:\n a preamble detector configured to detect a bit pattern of unit preambles repeatedly inserted into a received frame; a frame length detector located in a preamble field of the received frame and configured to detect a bit pattern of index preambles differently defined from the unit preambles, detect subsequent frame length information, and calculate a frame length value through a frame length value included as the frame length information and an error correction code; a delimiter detector configured to detect a delimiter bit pattern of the received frame; and a reset determiner configured to, when a time point at which the received frame ends is determined using the frame length value and a location of the delimiter detected by the delimiter detector, generate a reset signal for resetting the transimpedance amplifier of an optical transceiver.
