Abstract
The utility model provides an LC duplex optical adapter which comprises a rectangular hollow shell with two hollow ends and an isolated middle part; each end is provided with two interfaces; each interface is internally provided with a ceramic sleeve pin hole; the inner diameter of the hole is 1.25mm; the size of a fitting interface of the LC adapter is totally the same with that of an SC simplexadapter; the middle of the adapter is provided with a flange; two sides of the flange are provided with a connecting hole; and a flexible card is arranged on a connector of the adapter. The two interfaces of the LC duplex adapter are the same with the standard interface of an LC adapter and can be inserted into two single-chip LC adapters simultaneously. The LC duplex optical adapter can make fulluse of the existing resources, reduce waste and save the construction time; and the operation principle of the LC duplex adapter is the same with that of the LC single-chip adapter, which improves the density of an optical connector by times and increases the capacity by two times. The LC duplex optical adapter is characterized by simple structure, good using effect and the like.
Description
Technical field
The utility model relates to optical fiber communication, relates in particular to be applicable to the LC fiber adapter.
Background technology
The Optical Distribution Frame and the Fibre Optical Sensor of China and external existing optical fiber telecommunications system, the panel of instrument and meter adopts the SC connector mostly.China 3G engineering starts comprehensively at present, China Telecom, various optical fiber telecommunications systems such as move and original optical fiber telecommunications system is being carried out transformation and upgrade, service efficiency for raising equipment and distributing system, progressively substitute the existing SC joints of optical fibre with the small-sized LC joints of optical fibre, LC connector pin bore dia is 1.25mm, is half of SC connector pin bore dia 2.50mm.But existing LC fiber adapter, the single worker's adapter of mounting interface size and SC is different, and original distribution cabinet, distributing frame etc. just can not utilize in the time of substituting replacing, cause the significant wastage of resource.
Summary of the invention
The purpose of this utility model exactly overcome above-mentioned defective, a kind of LC duplex fiber adapter is provided.The purpose of this utility model can realize by following technical scheme: comprise an aerial isolated empty capsid in rectangle two, every is provided with two interfaces, be provided with the ceramic sleeve pin holes in each interface, the hole internal diameter is 1.25mm, the single worker's adapter of the mounting interface size of LC adapter and SC is just the same, this adapter middle part is provided with flange, there is connecting hole on the flange both sides, when one of adapter injects panel, can be fixed by bolts on the panel, also be provided with elastic card on the adapter connector, the another kind of fixed form is selected in the time of can supplying to install.Two interfaces of LC duplex adapter are identical with LC adapter standard interface, can insert two single core LC adapters simultaneously.Meet People's Republic of China's communication industry standard (YD/D 1272.1-2003) and IEC/PAS 61754-20 (2001) standard.The utility model can utilize existing resource fully, cuts the waste, and saves the engineering time, and LC duplex adapter principle of work is identical with the single core adapter of LC, and LC duplex adapter improves joints of optical fibre density exponentially, is increased to double capacity.
The utlity model has characteristics such as simple in structure, that result of use is good.
