A fiber optic connector for detachably (active) connection between the optical fibers and optical devices, it is the precision of the two end faces of the optical fiber butt up to the light emission energy to maximize the optical output coupled to the receiver to the fiber, effects due to its involvement and to the optical link and minimize impact on the system, which is a basic requirement of the optical connector. Certain extent, the optical connector and also affects the reliability of the performance of the optical transmission system specification describes insertion loss:. ≦ 0.5 dB numerical aperture: 0.5 core diameter: 1mm Cable Diameter: 2.2mm ~ 8.0mm core Material: PMMA Features ● Low insertion loss repeatability ● ● ● interchangeability high transmission ● resistance to electromagnetic interference and electromagnetic radiation scope of optical fiber communication systems ● ● ● fiber access network fiber sensor fiber optic data transmission ● ● Fiber Optic Test Equipment Connector Type ST, FC, SC, LC, SMA, SMI, etc. 1, ST 2, FC connector which was first developed by Japan's NTT. FC is Ferrule Connector abbreviation strengthen its external way is to use a metal sleeve, fastening means for the turnbuckle. First, FC type connectors, using the ceramic pin butt end surface is a plane-contact manner (FC). Such connectors simple structure, easy to operate, easy to produce, but the fiber end face dust is more sensitive and prone to Fresnel reflection, it is difficult to improve the return loss performance. Later, this type connectors made improvements butt end faces spherical pin (PC), while the external structure has not changed, so that the insertion loss and return loss performance has been improved greatly. 3, SC SC type developed by Japan's NTT fiber-optic connectors. Its shell rectangular structure size used in the coupling pin and sleeve type with FC identical, end of which pin to use more PC or APC Polishing way; fastening means is the use of plug pin latch type, without rotation. Such connector plug easy operation, small fluctuations in insertion loss, high compressive strength, high mounting density. SC fiber optic connector fully meet the EIA 604-4A, IEC, and JIS C5970, SC-NTT standard and YD/T-826-1996 standards, in line with internationally accepted GR-326 specification. Can form double continuation. 4, LC LC type connector is a (Bell) Research Institute name Bell developed. LC-type connector is a single plug and adapter with mini plug connectors composed. It is characterized by the use of a rectangular configuration, and the lever on the locking mechanism comprises a key and a coupling pin in the optical axis direction is applied with a resilient pin. Typical nominal outside diameter of the pin 1.25mm; plug has a plug-in, the switch can be used to locate and limit mating connector and the relative position between the components. Of the optical connector means is a rigid or flexible sleeve bore. 5, SMI SMI-SMI POF patch using self-developed industrial controls the production of plastic optical fiber transmission network dedicated SMI connector, compact bayonet design, structure, anti-pull, waterproof, anti-pressure design, low insertion loss, high precision coupling Positioning 6, SMA SMA connector is a widely used small threaded coaxial connector, which has a frequency bandwidth excellent performance high reliability. long life. SMA connector suitable for microwave devices and digital communication systems to connect the RF cable RF circuit or microstrip line. Shenzhen Huaying Century Optoelectronics Technology Co., Ltd.
