<P>PROBLEM TO BE SOLVED: To provide a burst signal receiver capable of separating a 10 G burst signal from a 1 G burst signal. <P>SOLUTION: The burst signal receiver 91 receives the 10 G burst signal and the 1 G burst signal, and includes: a low pass filter 19 which passes 1, 0 alternation included in a head preamble of the 1 G burst signal and blocks 1, 0 alternation included in a head preamble of the 10 G burst signal; a second bit number determining part 14 which performs a counting until the bit number of 1, 0 alternation from the low pass filter 19 reaches a second fixed number and outputs a low-speed set signal F1; and a first bit number determining part 13 which counts bit numbers of 1, 0 alternation included in the head preambles of the 10 G burst signal and the 1 G burst signal and outputs a high-speed set signal F0 after the low-speed set signal F1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
