Description

Technical Field

[0001] The utility model relates to an optical fiber cable pay-off frame, belonging to the technical field of optical fiber laying. Background Art

[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The fine optical fiber is encapsulated in a plastic sheath so that it can bend without breaking. Usually, 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, and the receiving device at the other end of the optical fiber uses a photosensitive element to detect the pulses.

[0003] The existing optical fiber is difficult to control during the pay-out process for the winding roller that receives the optical fiber, which may easily cause the optical fiber to be paid out too long due to excessive rotations, and thus requires manual reeling. After the optical fiber cable outside the winding roller that receives the optical fiber is paid out, it is difficult to quickly replace the winding roller, which affects the convenience of disassembly, assembly and replacement of the optical fiber winding roller on the pay-out frame. When the optical fiber is paid out, it is easy to loosen after the pay-out end loses its restriction, which easily causes the entire roll of optical fiber cable to loosen and become disorderly, and it is difficult to quickly cut the optical fiber after the required length is paid out, which affects the convenience of paying out the optical fiber.
