An optical unit includes photoelectric conversion modules, a plurality of adapter support members whose upper parts are rotatably supported, and a plurality of optical connector adapters attached to lower ends of the adapter support members so as to be arranged next to each other, the optical connector adapters being contained in the optical unit. The adapter support members are rotated separately so that the optical connector adapters are extracted outside from the optical unit with a space formed between each adjacent two of said optical connector adapters. Each of the optical connector adapters has insertion holes to which optical connectors of optical fibers extending from the photoelectric conversion modules and optical connectors of external optical fibers are connected.

Optical unit with increased reliability

The present invention relates to a breaker apparatus and breaker unit. The breaker apparatus comprises a breaker unit including a power supply/cut-off breaker part, a power connecting part, a first unit connecting part, a ground connecting part and a second unit connecting part and further comprises a breaker unit mounting board including a mating power connecting part, a mating ground connecting part, a first connection mediating part and a second connection mediating part. This breaker apparatus is capable of constituting a power distributing apparatus with a necessary but minimized construction, and of extending the breaker unit in a minimum unit according to necessity. In addition, with this breaker apparatus, parts can be used in common irrespective of a change of a ground system, and further, can be replaced in the hot-line condition without cutting off the power supply to a system.
