Abstract: The application discloses an optical cable assembly and an optical cable testing method. The optical cable assembly comprises: an optical cable wire with a test end; a spool for winding the optical cable; a connection assembly has an optical cable connection port and a test port, the connection assembly is configured to connect objects at both ends of the connection assembly, and the test end of the optical cable is connected to the connection assembly as an object at one end of the optical cable connection port, the test port is located at an operable area of the spool, configured to connect the test equipment to form an optical path between the test equipment and the optical cable wire when the optical cable is tested.

Abstract: The present disclosure provides a cross-linking enhanced meta-aramid and a preparation method therefor. In the method, an isocyanate is used as a cross-linking agent, treatment is performed for a period of time at a certain temperature after a catalyst is added, and then water washing, drying, and heat setting are performed to prepare a high-strength meta-aramid. With the present disclosure, a cross-linked meta-aramid is prepared and has an improved binding force between fibers and has excellent mechanical properties and high temperature resistance.
