The function of the fiber adapter

Update:2018-01-15

Fiber optic adapter (also known as flange, lotus coupling) is a connection part of the optical fiber active connector. The adapter has the standard type and the conversion type, also called the flange plate. Jumper, pigtail, terminal box will use adapters. The main function is the connection between the equipment and the equipment. For example, a jumper, an adapter is installed at both ends of an optical fiber, called a jumper. In the end of optical fiber adapter installed, called pigtail. Now there's a set-top box in the home watching TV. A small metal circular device behind the set-top box is an adapter.
Including FC, SC, ST, LC, MTRJ and other models, there are other products that are transferred to each other, such as ST-SC, FC-ST and so on. They are widely used in optical fiber distribution frame (ODF), optical fiber communication equipment, test instruments and so on, and their performance is stable and reliable.
Characteristic:
Good compatibility, small optical concentricity error
Two zirconia ceramics or precise phosphorous bronze bushing
Machining dimension of high precision machine
High reliability, stability
The insertion loss is low, the echo loss is high, and the exchange performance is good.
Three kinds of PC, UPC and APC
Use:
Telecommunication network, metropolitan area network and optical fiber communication system
Optical fiber test instrument / instrument
Optical fiber CATV and optical fiber sensors
Optical fiber broadband access network, FTTH fiber entry
Fiber wiring frame, frame type and wall hanging fiber wiring unit
Performance indicators:
Insertion loss: 0.3dB (PC) = 0.2dB (UPC) <0.2dB (APC) = 0.3dB (multimode)
The return loss is not less than 40dB (PC) = 50dB (UPC) = 60dB (APC) = 35dB (multimode)
Interchangeability: less than 0.2dB
Working temperature (centigrade): -30 - +80
Storage temperature (centigrade): -40 - +85
Vibration test: 0.1dB (10-60Hz, 1.5mm amplitude)
Tensile strength test: 0.1dB (0-15Hg 0.9mm diameter fiber tension, except)
Repeatability: more than 1000 times
Industrial standard: Bellcore TA-NWT-001209
