Classification of fiber optical connectors
1.The fiber optical connector is installed on both ends of a portion of optical fiber, which is utilized as optical wiring.
2.Classification according to fiber type: single-mode fiber connector, generally G.642 fiber, inner diameter 9um, outer diameter 125um; multimode fiber connector, one is normally G.651 fiber, inner diameter 50um, outer diameter 125um, the additional The species comes with an inner size of 62.5um and an outer diameter of 125um.
3.Based on the classification of optical fiber connectors: FC, SC, ST, LC, MU, MTRJ, etc. FC type (ferrule connector) --- The external reinforcement is constructed of metal sleeve, and the fastening method is screw buckle. Commonly known as round head. SC type --- The shell is made of molding technology, manufactured from molded glass fiber plastic, which is rectangular, the pin is constructed of precision ceramics, the coupling sleeve is a metal slotted sleeve structure, the fastening method is plug-in, not want to rotate. Often called square head. LC type --- The outer diameter of the sleeve is 1.25mm, usually half of the outer diameter of FC-SC, ST sleeve is 2.5mm, which enhances the application form density of the connector.
4.The performance of the fiber optical connector mainly includes optical performance, interchangeability, mechanical performance, environmental performance and life. The most crucial of the are the two indicators of insertion loss and return loss.
Main parameters of optical module
1.Optical module transmission rate: 100M, Gigabit, 10GE, etc.
2.Transmitting optical power and getting sensitivity of the optical module: Transmitting optical power identifies the light intensity at the transmitting end, and receiving sensitivity refers to the light intensity which can be detected. Both of these essential parameters affect the transmission distance. The transmission distance of the optical module is principally tied to both loss and dispersion.
3.10GE optical module follows the 802.3ae standard, the transmission distance relates to the kind of optical fiber used, and the optical performance of the optical module. Further reading: Explain the difference between SFP, SFP + and XFP optical modules at length
4.Saturated optical power value identifies the utmost detectable optical power at the getting end of the optical module, which is normally -3dBm. When the received optical power is higher than the saturated optical power, bit errors will happen.
