Description

Technical Field

[0001] The present application relates to the field of optical fiber technology, and in particular to an optical fiber clamping and alignment device. Background Art

[0002] Optical fiber is short for optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is "total reflection of light". The fine optical fiber is encapsulated in a plastic sheath, which allows it to bend without breaking. Generally, the transmitting device at one end of the optical fiber uses a light-emitting diode or a laser to transmit light pulses to the optical fiber. During the use of current optical fibers, a fiber holder is required so that the optical signal in the optical fiber can be better coupled to the holder and received.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the existing optical fibers lack a structure for positioning and aligning the optical fibers during coupling, which makes it easier for optical fiber coupling to produce deviations, leading to failure of optical fiber coupling.
