Are the couplers and flanges of fiber optics the same thing?
For waveguide optical fiber couplers, typically a component with a type Y branch, the optical signal that is fed by a fibre can be used for an equal division. When the coupler branch road open Angle increased, the increase in the number of light will leak in the cladding that increased the excess loss, so the open Angle generally within 30 °, thus the length of the waveguide type optical fiber coupler can't be too short.
Fiber Coupler (Coupler) is also called the differences (Splitter), connectors, adapter, optical fiber, flange plate is used to implement optical signal shunt/road, or used to extend the components of optical fiber link, belongs to the field of optical passive components, in the telecommunications network, cable television network, the user will be applied to the circuit system, local area network.
Fiber coupler is removable (activities) between optical fiber and optical fiber connection device, it is to put the fiber of two surface precision docking, so that the optical output of light energy to maximize the coupling to the receiving optical fiber, and optical link and its intervention to minimize the effects on the system
