3. cassette splitter its minute only directly draws by tail optical fiber, lacks light splitting mouth, need to lodge outside adapter and be used as light splitting mouth.
[summary of the invention]
The utility model is intended to address the above problem, and provides a kind of simple in structure, external hanging type light shunt module easy to use.
For achieving the above object, the utility model provides a kind of external hanging type light shunt module, this external hanging type light shunt module comprises box body, be located at the input cable of described box body outside, be located at a plurality of light splitting mouths, min-size optical splitter and a plurality of tail optical fiber of described box body inside, the optical fiber of described input cable inside is divided into a plurality of tail optical fibers by described min-size optical splitter, and the plurality of tail optical fiber is corresponding with described a plurality of light splitting mouths.
Described input cable wrap is drawn together optical cable, the joints of optical fibre that are connected with optical cable and the anti-sheath of turning round of optical cable is installed.
Described optical cable from inside to outside comprises optical fiber, reinforcing sleeve, oversheath successively.
Described box body comprises upper cover and lower cover, and described lower cover bottom is provided with at least one magnet, and described lower cover bottom margin is provided with hangers.
Described light splitting mouth is arranged on side of described box body or end face.
Contribution of the present utility model is, it efficiently solves the problem that existing optical branching device exists, and has following beneficial effect:
1. input cable, can be directly and external cable welding operation directly by drawing in miniature Light splitter toy, saving activity interface, and reduction link load, enters also to save together tail optical fiber and fiber adapter.
2. volume is little, flexible for installation.Magnetic adsorption type is installed, and not limited by installing space position and installation direction, is specially adapted to install in panel beating distribution plant.
3. external hanging type, addition type are installed, and on-line operation communication line is not affected, and can accomplish not shut down installation exercise.
4. external hanging type separate configurations, is not subject to existing equipment configuration affects.Even also can carry out dilatation, increase-volume operation in the situation of full configuration in existing equipment.
5. for the one-level splitting network pattern in network arrangements, can directly escalate into secondary light-splitting pattern, increase cladding thickness and the degree of depth of fiber optic network.Do not need the resource of existing Access Network and equipment to carry out any transformation.
