ABSTRACT:
An optical fiber evaluation test station (20) includes optical fiber supply (26), translation, and rewinding mechanisms (52), and at least one module performing a test of optical fiber quality through which the optical fiber (22) continuously passes. The test station (20) includes a supply section wherein the optical fiber (22) is paid out from a supply spool (24) and cleaned by a cleaning and static discharging unit (30). There is a high tension test section wherein tests such as a buffer cure test (46) and a bend proof test (48) are performed. In a low tension test section, tests such as an optical fiber diameter test (58), a buffer flaw test ( 60 ), and a visual observation test (64) are performed. Tension-isolating capstans (40, 44) separate the various sections, optical fiber guides (62) direct the optical fiber (22) and stabilize its movement, and spring-mounted dancers (36, 42) measure the tension in the optical fiber (22) in the tension-isolated sections.
