  • Patent number: 8520201
    Abstract: An optical signal inspection device includes a housing, a diagnostic unit, an optical specimen holder, a light-shielding module, and a guiding unit. A receiving space is defined internally of the housing. The housing has an optical fiber holding area formed thereon. The optical specimen holder has an upper jaw member and a lower jaw member. The light shielding module has a main body and two lateral shielding members disposed thereon. Two side portions of the lower jaw member are formed matchingly to the lateral shielding members. The guiding unit is secured to the upper or lower jaw member. When the upper and lower jaw members are used to clamp the optical fiber for inspection, interference due to ambient lighting can be prevented by the light shielding module. Thus, quick and accurate inspection results can be obtained by the user.
