May I ask the prawns to help me explain, "coupler" and "flange" mean the same thing, if not, what's the difference between them? Forget everyone, pointing out!!In the first time
The same thing, the fiber coupler, also known as the optical fiber flange.Optical fiber coupler (Coupler) splitter (Splitter), also known as optical fiber connector, adapter, flange, is used to realize optical signal splitter / combiner, or to extend the fiber link element, belonging to the optical passive components, in a telecommunication network, cable TV network, will be applied to all households loop system, local area network in.
For a waveguide type fiber coupler, it is generally a component with Y - type branching, and the optical signal input by one optical fiber can be divided into equal parts. When the opening angle of the coupler branch increases, the leakage of light to the cladding will increase, resulting in excessive loss, so the opening angle is generally within 30 degrees, so the length of the waveguide type fiber coupler can not be too short.
Fiber coupler is removable between the optical fiber and optical fiber (active) connection device, it is the two fiber surface precision docking, so that the optical output of the light energy to maximize the coupling to the receiving optical fiber, and the effect of intervention on the system caused by the optical link to minimize the.
