SOLUTION: For example, when the output level of the signal light of the connection side of an optical fiber 7 is larger than that of the signal light of the connection side of an optical fiber 8, the pass loss of the fiber 7 is increased by providing a light attenuating function part 9 in the fiber 7 and by expanding the core of the arbitrary oposition of the part. Then, the optical fiber 7 in which the pass loss is increased in such a way is connected to a connection terminal 11 in which the output level of the signal light of an optical branching coupler 3 is larger. Thus, both output levels of signal lights to be outputted from respective output terminals 11, 12 of optical fibers 7, 8 for respective output terminals are matched with each other by transmitting respective signal lights to be outputted from the optical coupler 3 to the optical fibers 7, 8 for plural output terminals.

Abstract: PURPOSE:To sinter a composition together with a resistor simultaneously by containing 0.05-3 pts. by wt. of Ta2O5, powder and/or Sb2O3 powder or 0.05-3 pts. by wt. (in conversion into oxides) of a Ta compound and/or a Sb compound which can be converted into oxides. CONSTITUTION:To 100 pts. by wt. of a conductive powder, 0.05-3 pts. by wt. of Ta2O5, and/or Sb2O3 is added. The Ta2O5, and/or Sb2O3 has an effect to retard sintering of the conductive powder and consequently, tensile stress applied to the resistor becomes small at 500-600 deg.C and crack formation is suppressed. In the case the ratio of Ta2O5 and/or Sb2O3, is less than 0.05 pts. by wt., Ta2O5 and/or Sb2O3 is not effective to retard the sintering and in the case the ratio exceeds 3 pts. by wt., sintering can not proceed at the sintering temperature. Ta2O5 and/or Sb2O3 may be added as oxides and a Ta compound and/or a Sb compound which become oxides by sintering may also be used and added in a range from 0. 05 to 3 pts. by wt. (in conversion into oxides).
