Abstract

The invention discloses a single skeleton for winding multiple optical fibers, and the skeleton comprises baffle plates, a winding shaft, and a supporting sleeve. The baffle plates comprises a first baffle plate, a second baffle plate, and at least one central baffle plates located between the first and second baffle plates. The invention also discloses a method for winding multiple optical fibers through the skeleton, and comprises six steps. Through the six steps, the method achieves the quick winding, makes reasonable use of the space of the skeleton, improves the environment adaptability of the optical fibers, and enables the skeleton to have good temperature environment adaptability. The skeleton can achieve the winding of multiple optical fibers thereon, and the adjacent optical fibers are isolated through the baffle plates. Moreover, the limited space is used reasonably, and the size is reduced.

Description

technical field [0001] The invention relates to a single framework for coiling multi-segment optical fiber rings, and a method for coiling multi-segment optical fiber rings using the single framework. Background technique [0002] The wavelength division multiplexing system uses optical signals of multiple wavelengths to realize communication. When multiple signals arrive at the same receiving end through channels with different optical paths, in order to synchronize the optical signals of each channel, it is necessary to access Fiber delay loops with different fiber lengths are implemented. Under the condition of unlimited structure, multiple fiber delay loops with skeletons can be connected in the system, but in the case of limited volume, it is necessary to consider saving space and adopt the structural form of multiple delay coils coiled on a single skeleton. . [0003] However, the current optical fiber coiling technology cannot directly coil multiple segments of opti...

Problems solved by technology

[0003] However, the current optical fiber coiling technology cannot directly coil multiple segments of optical fiber on a single backbone

For example, after winding the first section of optical fiber, and then coiling the second section of optical fiber directly on it, the second section of optical fiber will squeeze the pigtail of the first section of optical fiber, which will cause the insertion loss of the first section of delay fiber to change. If the third fiber is coiled directly on the second fiber, the third fiber will squeeze the pigtail of the second fiber, resulting in the insertion loss of the second delayed fiber become larger or even the pigtail breaks

[0004] In addition, since the frame of the commonly used fiber delay ring is made of metal, when the ambient temperature changes, the expansion performance mismatch between the fiber coil and the metal frame will cause the performance of the fiber delay ring to deteriorate, thereby restricting the performance of the fiber delay ring. the widespread use of
