Abstract

PURPOSE:To eliminate tangling of an optical fiber when it is coupled with a cable and to improve the operability by forming an upper/lower two-stage structure inside, providing an optical component storage space and an excessive- length optical fiber storage part at the lower stage and with an optical connector storage part at the upper stage, and partitioning the upper and lower stages with an intermediate lid and an optical fiber lead-in part. CONSTITUTION:A case main body 1 is partitioned into the upper and lower stages with the optical fiber lead-in part 4 and intermediate lid 9 and the optical component storage space 2 and the excessive-length optical fiber storage part 3 which is formed between the inside of the case main body 1 and a guide formed of a pin 8 for optical fiber movement prevention are provided in the lower partitioned stage of the main body 1. The upper stage of the storage case main body 1 is provided with the optical connector storage part 5. Therefore, optical components and an excessive-length optical fiber, and an optical connector 13 can be sectioned and stored in the upper and lower stages. Consequently, many optical fibers can be stored without tangling and the operability can be improved.
