Abstract
The invention discloses an LC (Liquid Crystal) single-mode ceramic ferrule. The LC single-mode ceramic ferrule is arranged at the center of an optical fiber connector, and is matched with a metal seat; a ceramic ferrule main body is cylindrical; one segment of an end of the ceramic ferrule is a tapered end; the tapered end is frustum-shaped; a conical groove is arranged at an inner hole of the other end of the ceramic ferrule; the length of the ceramic ferrule is 6.50+/-0.05mm, the inner diameter of the same is 0.125-0.126mm, the outer diameter of the same is 1.2499+/-0.0005, and the concentricity of the same is not larger than 1 microns. As the ceramic ferrule main body is cylindrical, one segment of the end of the ceramic ferrule is the tapered end, the tapered end is frustum-shaped, and the conical groove is arranged at the inner hole of the other end of the ceramic ferrule, the purposes of low optical coupling loss of the ferrule, accuracy in connection and positioning, convenience for use, attractive appearance and stable performance are achieved, optical signal transmission speed can be greatly increased, and service life can be greatly prolonged.
Description
Technical field
The present invention relates to optical-fibre communications field, be specifically related to a kind of LC single mode ceramic insertion core.
Background technology
The joints of optical fibre are the butt joint of two end face precisions of optical fiber, and the luminous energy of launching fiber output is coupled in the reception optical fiber to greatest extent.Lock pin is the core component of this joints of optical fibre, puts into practice and studies show that sleeve pipe and the lock pin that metal material is made, and aspect wearing quality, temperature stability, rotproofness, all exists not enough.The optical fiber communication connector of producing both at home and abroad, the lock pin in the adapter extensively adopt the zirconia ceramic material at present, it be a kind of by the nanometer titanium dioxide zirconia material through a series of prescriptions, the high precision special cermacis element that processes, made connector is a fiber active linker detachable, classification, make connection, the conversion scheduling of optical channel more flexible, can for the light way system debugging and maintenance.
Therefore, ceramic insertion core will guarantee that in use light path is unimpeded, and loss of signal is little; On version, require connector right alignment height, smooth surface, pulling capacity is moderate, and is easy for installation, durable in use.
Summary of the invention
For solving the problems of the technologies described above, it is little that we have proposed a kind of optical coupling loss, connects accurate positioning, easy to use, good looking appearance, stable performance, and the LC single mode ceramic insertion core that can improve the light signal transmission speed greatly and increase the service life.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of LC single mode ceramic insertion core is installed in joints of optical fibre central authorities, and the complexed metal seat uses, and described ceramic insertion core main body is cylindrical shape; One section tapered termination, described ceramic insertion core one termination; Described cone-shaped end is round table-like, and the length of described ceramic insertion core is 6.50 ± 0.05mm, and internal diameter is between 0.125-0.126mm, and external diameter is 1.2499 ± 0.0005mm, and concentricity is not more than 1 μ m.
Preferably, another endoporus place, termination of described ceramic insertion core is provided with cone-shaped groove.
Pass through technique scheme, the present invention is by becoming cylindrical shape with described ceramic insertion core body design, one termination of described ceramic insertion core is designed to cone-shaped end for one section, described cone-shaped end is round table-like, another endoporus place, termination is provided with cone-shaped groove, it is little to have reached lock pin optical coupling loss, connects accurate positioning, easy to use, good looking appearance, stable performance, and the purpose that can improve the light signal transmission speed greatly and increase the service life.
