Abstract

An optical splitting apparatus includes an enclosure, an even optical splitter and an uneven optical splitter that are disposed in the enclosure. A light inlet and a plurality of light outlets are disposed on the enclosure, and fiber adapters are disposed on the light outlets. The light inlet, the even optical splitter, the uneven optical splitter, and the light outlets are connected, so that optical paths are formed between the light inlet and the light outlets by using the even optical splitter and the uneven optical splitter. The light inlet is connected to at least one of a light input end of the even optical splitter and a light input end of the uneven optical splitter, and the fiber adapter on the light outlet is connected to at least one of a light output end of the even optical splitter and a light output end of the uneven optical splitter.

First claim

a light inlet disposed on the enclosure; and
a plurality of light outlets disposed on the enclosure, and fiber adapters are disposed on the plurality of light outlets; and
wherein the light inlet and the plurality of light outlets are connected through the uneven optical splitter, so that optical paths are formed between the light inlet and the plurality of light outlets;
wherein an output optical power of the first light output end of the uneven optical splitter is higher than an output optical power summed over all light output ends of the second set of light output ends of the uneven optical splitter, and wherein the first light output end is configured to connect to a next node, and the second set is configured to connect to users;
wherein an optical fiber connector is disposed on each of light output ends of the uneven optical splitter and is detachably fastened and connected to the fiber adapters disposed on the plurality of light outlets; and
wherein all light output ends of the uneven optical splitter are connected to the plurality of light outlets in a one-to-one correspondence through optical fiber connectors disposed on the light output ends of the uneven optical splitter and the fiber adapters disposed on the plurality of light outlets.

2. The optical splitting apparatus according to claim 1 , wherein each light output end of the second set has a same output optical power.
