Background technology
Low-loss temperature-measuring optical fiber composite aerial phase line is the novel product in transmission system, having transmission of electricity, thermometric, communication three kinds of functions concurrently, in the sleeve pipe of the stainless steel sleeve pipe fiber unit in phase line, being provided with multimode optical fiber, the single-mode fiber for communicating, fine cream for thermometric.Because multimode optical fiber is relatively stricter to the attenuation requirement of optical fiber in the application of thermometry, decay bound has corresponding regulation, if meet this attenuation requirement, the decay for the single-mode fiber communicated will higher than conventional levels.In order to control optical fiber attenuation, guarantee that thermometric, communication function are good, effective way is realized by long (namely adjusting the radius-of-curvature of optical fiber in sleeve pipe) more than adjustment optical fiber is in sleeve pipe, make two kinds of different optical fiber in sleeve pipe more than the long gap having 0.3%-0.5%.The production method of current stainless steel sleeve pipe fiber unit requires it is the same to the dissimilar optical fiber excess length in same pipe, realize remaining long scope difference 0.3%-0.5% ten points of difficulties between dissimilar optical fiber.
Summary of the invention
In order to overcome the deficiency of the production method of the stainless steel sleeve pipe fiber unit in existing fiber composite aerial phase line, the invention provides a kind of production method of stainless steel sleeve pipe fiber unit of optical phase conductor.The method can realize the control to the excess fiber length of dissimilar optical fiber in stainless-steel tube, thus reach control multimode optical fiber decay bound, the more low-loss object of single-mode fiber maintenance, meet the requirement of remaining long scope difference 0.3%-0.5% between dissimilar optical fiber.
The production method of the stainless steel sleeve pipe fiber unit of a kind of optical phase conductor provided by the invention, aborning fine tension force is put to multimode optical fiber and be adjusted to 40 grams by original 70 grams, single-mode fiber is put fine tension force and be adjusted to 85-90 gram by original 70 grams, use 25 DEG C, shearing is the fine cream of high viscosity of 50 (1/S), viscosity >=12pas, the filling temp of fine cream is increased to 88-90 DEG C by original 80 DEG C.
The invention has the beneficial effects as follows: the control to the excess fiber length of dissimilar optical fiber in stainless-steel tube can be realized, thus reach control multimode optical fiber decay bound, the more low-loss object of single-mode fiber maintenance, meet the requirement of remaining long scope difference 0.3%-0.5% between dissimilar optical fiber.Use the present invention can carry out the production of the stainless steel sleeve pipe fiber unit of optical phase conductor smoothly, thermometric, the communication function of the product made are good.
