PURPOSE:To provide the optical transmission and reception circuit in which a dynamic range for an optical reception section is reduced to reduce substantially even a dynamic range for an optical transmission section. CONSTITUTION:In the optical transmission and reception circuit consisting of a 1st optical transmission and reception section 3 making up of m-sets (m is a positive integer) of optical transmission sections 31, 32 and n-sets (n is a positive integer) of optical reception sections 33 and consisting of a 2nd optical transmission and reception section 4 making up of n-sets of optical transmission sections 41, and m-sets of optical reception sections 42, 43 making counter- communication with each other, transmission power of other optical transmission section provided with one optical reception section is controlled by a control voltage generated by the one reception section in each optical transmission reception section. |
