Abstract:
1. An optical fiber attenuator comprising: a connector unit including: an insert component including: wherein the through hole of the connector unit has a large-diameter hole portion formed in the first shell part, and a small-diameter hole portion formed in the second shell part and having a diameter smaller than that of the large-diameter hole portion, the shell member further having a shoulder portion at a junction of the large-diameter hole portion and the small-diameter hole portion, wherein the small-diameter hole portion includes a first segment adjacent to and in spatial communication with the large-diameter hole portion, a second segment adjacent to and in spatial communication with the first segment, disposed opposite to the large-diameter hole portion and having a diameter that is gradually reduced in a direction away from the large-diameter hole portion, and a third segment adjacent to and in spatial communication with the second segment, disposed opposite to the first segment and having a diameter greater than that of the second segment, and wherein the attenuation unit includes a pin base disposed in the first and second segments, a first pin extending from the pin base and extending through the third segment, and a second pin extending from the pin base in a direction opposite to the first pin, the pin base abutting against the second shell part at the second segment, each of the first pin and the second pin to be mounted with an attenuation fiber therein.
