Description

A kind of heat safe optical fiber connector
Technical field
The utility model is related to photoelectric communication technical fields, more particularly to a kind of heat safe optical fiber connector.
Background technology
Optical fiber connector is the device for carrying out detachable (activity) between optical fiber and optical fiber and connecting, its two optical fiber End face precision docking is got up, so that the light energy of launching fiber output can be coupled in reception optical fiber to the maximum extent, and is made It influences to minimize caused by system since it intervenes optical link, this is the basic demand of optical fiber connector.In certain journey On degree, optical fiber connector affects the reliability and properties of optical transmission system.
Optical fiber connector can be divided into the single mode and multimode connector of common silica-based optical fibers by the difference of transmission medium, also It is other such as with modeling
Glue etc. is the optical fiber connector of transmission medium;It can be divided by connector structure type:FC、SC、ST、LC、D4、DIN、 MU, MT etc. various forms.Wherein, ST connectors are commonly used in wiring unit end, such as fibre distribution frame, optic module;And SC and MT connectors are commonly used in network equipment end.There are FC, PC (including SPC or UPC) and APC by fiber end face shape point;It presses Fiber number divides point for also having single and multicore (such as MT-RJ).Optical fiber connector is widely used, various in style.Actually answering With in the process, we are distinguish generally according to the difference of fibre-optic connector structure.It is some now common optical fiber below Connector:
FC type optical fiber connectors:
This connector is developed by Japanese NTT earliest.FC is the abbreviation of Ferrule Connector, is shown outside it Reinforcement mode is to use metallic sheath, and fastening means is thread.Earliest, the connector of FC types, pair of the ceramic contact pin of use Contact surface is flat surface contact manner (FC).Such connector construction is simple, easy to operate, is easy to make, but fiber end face is to micro- Dirt is more sensitive, and easy tos produce Fresnel reflection, and it is more difficult to improve return loss performance.Later, to the type connector It improves, using the spherical contact pin (PC) in docking end face, and external structure does not change so that insertion loss and echo damage Consumption can have raising by a relatively large margin.SC type optical fiber connectors:
This is a kind of optical fiber connector developed by Japanese NTT companies.Its shell is rectangular, used contact pin with couple The structure size of sleeve is identical with FC types.The end face of wherein contact pin mostly uses PC or APC type lapping modes;Fastening means is Using insert-pull pin bar-type, it is not required to rotate.Such connector is cheap, and plug is easy to operate, and small, pressure resistance is fluctuated in insertion loss Degree is higher, and packing density is high.
ST and SC interfaces are the two types of optical fiber connector, and for 10Base-F connections, connector is typically ST Type, for 100Base-FX, connector is SC types in most cases.The core of ST connectors is exposed, and SC connects The core of device is connect inside connector.
Biconical connector (Biconic Connector):
Most representative product is developed by AT&T Labs of the U.S. in this kind of optical fiber connector, it is by two through essence The coupling assembly of cylinder plug and an inside equipped with biconial plastic sleeve of the end of close die forming in the form of a truncated cone Composition.DIN47256 types optical fiber connector this be it is a kind of by Germany exploitation connector.The contact pin and coupling that this connector uses The structure size of trap cylinder is identical as FC types, and end face processing uses PC polishing mode.Compared with FC connector, structure will answer It is more miscellaneous, there is the spring of control pressure in inner metal structures, it can be to avoid damage end face due to grafting pressure is excessive.In addition, The mechanical precision of this connector is higher, thus insertion loss value is smaller.
MT-RJ type connectors:
MT-RJ is started in the MT connectors of NTT exploitations, carries latch mechanism identical with RJ-45 type LAN electric connectors, By being installed on the guide pins of small molded cannula both sides to quasi-fiber, for ease of being connected with optical transceiver, connector ends optical fiber For twin-core (interval 0.75mm) arrangement design, it is primarily used for the next-generation high-density optical fiber connector of data transmission.
Lucent Connector:
Lucent Connector is that famous Bell (Bell) research institute researchs and develops out, is inserted using easy to operate modularization Hole (RJ) latch mechanism is made.The size of its used contact pin and sleeve is the half of size used in common SC, FC etc., is 1.25mm.The density of optical fiber connector in fibre distribution frame can be improved in this way.Currently, in terms of single mode SFF, the company of LC types Connect that device is practical to have already taken up leading position, the also rapid development of the application in terms of multimode.
MU type connectors:
MU (Miniature unit Coupling) connector be based on current most commonly used SC connector, The single fiber-optic connector minimum in the world for developing out by NTT,.The connector using 1.25mm diameters casing and Self-retaining mechanism, it is advantageous that high-density installation can be realized.Using the casing of the l.25mm diameter of MU, NTT has been developed MU series connectors.They are useful for the socket-type connector (MU-A series) of optical cable connection;Bottom plate with self-retaining mechanism Connector (MU-B series) and simplification socket (MU-SR series) etc. for connecting LD/PD modules and plug.With optical network Network to the rapid development in bigger bandwidth more capacity direction and the extensive use of DWDM technologies, also will by the demand to MU type connectors It increases rapidly.
MC connectors:
Domestic communication company's independent research in 2012 is a than LC connector volume smallers, the higher MC connections of density Device.Day sea MC fiber active linkers are a kind of high density single-core fiber flexible jumpers, suitable for various high density occasions, such as Large capacity central machine room and high-density data center.MC fiber active linkers density is high, is reached as high as in identical space To twice of LC connectors, it can be rated as the current volume minimum in the world, the highest a connector of density.
Currently, with the continuous development of home communications cause, practical stage, and the range applied have been stepped into fiber optic communication It is increasingly wider.China now for optical fiber connector used in optical communication system, or use inlet outlet connector, or with into So-called " loose mails " such as the porcelain bushings and peripheral metal part of mouth is assembled at home, or according to institute's introduction of foreign technology and pass Button apparatus is produced, mainly FC types optical fiber connector.Traditional FC types optical fiber connector its coupling accuracy in the high temperature environment It can reduce, or even can not use.
