Description
Technical Field
The invention relates to the technical field of optical fiber ribbon testing, in particular to an optical fiber ribbon torsion measuring device and a measuring method.
Background
Under the guidance of the construction of novel infrastructures represented by information communication facilities such as 5G, industrial internet, internet of things and the like, the high-quality development of digital economy drives the social digitization and the informatization level to be continuously deepened, and the digitization applications such as industrial production, internet of vehicles, remote medical treatment and the like put higher and higher demands on the performances such as bandwidth, time delay and the like of the information communication network. The optical fiber ribbon is a basic element for constructing an information communication network, and the improvement of network performance requirements also puts more requirements on the deployment of the optical fiber ribbon.
Optical fiber ribbons laid in current communication networks can be divided into two structural forms: discrete optical fiber ribbons and optical fiber ribbons. The discrete optical fiber ribbons mean that each optical fiber ribbon is independent from each other and is dispersedly placed in the optical cable; the optical fiber ribbon is a thin flat ribbon formed by parallelly arranging discrete optical fiber ribbons and curing the discrete optical fiber ribbons by ultraviolet irradiation, and the optical fiber ribbons can be divided into 2-core ribbons, 4-core ribbons, 6-core ribbons, 12-core ribbons and the like according to different quantities of the cured optical fiber ribbons. Compared with a discrete optical fiber ribbon structure, the optical fiber ribbon enables the organization of the optical fiber ribbon to be more compact, the density of the optical fiber ribbon is easy to promote, and the optical fiber ribbon has great advantages in the aspects of promoting the number of optical fiber cores and optimizing the outer diameter of the optical fiber. Under the condition that the current urban pipeline resources are in shortage, more optical cables can be laid in a unit pipeline space by adopting the optical fiber ribbon optical cables, and the utilization rate of the pipeline resources is effectively improved. Fiber optic ribbon cables have become an effective solution to increase metropolitan network broadband capacity.
Due to the structure of the optical fiber ribbon, the optical fiber ribbon usually has a certain torsion phenomenon, when the optical fiber ribbon is influenced by changes of conditions such as environmental temperature, the torsion degree of the optical fiber ribbon can be increased, the mechanical and optical performances of the optical fiber ribbon are further influenced, and the quality of a circuit is deteriorated, so that a residual torsion degree test of the optical fiber ribbon is necessary, and the optical fiber ribbon is ensured not to be excessively twisted to cause performance degradation after being aged in the environment.
The current method for measuring the residual twist of Optical fibers is mainly carried out according to a method G8 in IEC60794-1-23< Optical fiber cables-Part 1-23: general specification-Basic Optical Cable test procedures-Cable element test methods >, and the brief steps are as follows: the optical fiber ribbon with the length of 50cm is vertically fixed, a load of 100g is clamped at the lower end of the optical fiber ribbon, the optical fiber ribbon is manually adjusted to be vertically stable, then the optical fiber ribbon is released to be naturally twisted, the angle index clamped on the optical fiber ribbon is stably used by a pointer to test the rotation angle, and the residual twist degree is calculated by combining the angle and the length of the optical fiber ribbon.
In the test apparatus given in the standard, since the weight of the angle measuring finger is not taken into consideration, the load actually applied to the optical fiber ribbon is more than 100g, and thus a certain deviation is caused in the test result. In the test device described in the patent literature that can be inquired in China at present, the angle measurement is carried out by adopting a mode that a light source irradiates an optical fiber ribbon, and the method has certain defects: 1) whether the optical fiber ribbon is in a vertical suspension state or not is difficult to determine, and when the optical fiber ribbon does not reach the vertical state, the projection of the optical fiber ribbon irradiated by a light source deviates from the center of the circle of the dial disc; 2) when the optical fiber ribbon rotates, the projection of the optical fiber ribbon irradiated by a light source can be widened, which brings certain difficulty to angle reading; 3) the rotation angle of the optical fiber ribbon is measured at the position where the optical fiber ribbon projects thinnest, and certain uncertainty exists in the judgment of the thinnest projection position. The three disadvantages mentioned above all bring about different degrees of errors in the measurement results.
