★Fiber Optic Splice Closures (FOSC) inspecting and testing items
Inspecting item | Technical Requirements | Inspecting type | |
Routine test (Before leaving factory) | Type test | ||
Package | Each small package contains one fiber optic splice closure, together with its accessories, tools, installation manual and packing list. | full | At least 3 sets sampled each time |
Appearance | Intact in shape, no burrs, bubbles, chaps, pores, warps, impurities and other defects, all background colors should be even and continual. | ||
Sign | There is a clear sign on the housing, such as name and model of the product, etc. | ||
Fiber storage device | The fibers reserved are to be winded in fiber optic splice tray (FOST), the length of fibers housed in FOST is ≥1.6m, the curved radius is >30mm. During the installation and maintenance, there should be no attenuation on fibers. | At least 3 sets sampled each time | |
Electrical jointing device | Inside FOSC: metallic components of fiber cables has the functions of electrical putting through, earthing connection and disconnecting. It is possible to install earthing deriving device outside the housing | ||
Sealing performance | After sealing according to the stipulated operation procedures, the injected air pressure is 100KPa±5Kpa, when immersed in clean water of normal temperature for 15 minutes, there should be no air bubbles, then observed for 24 hours, there should be no change of air pressure. | ||
Re-sealing performance | After reopening and resealing according to the stipulated operation procedures, the injected air pressure is 100KPa±5Kpa, when immersed in clean water of normal temperature for 15 minutes, there should be no air bubbles, then observed for 24 hours, there should be no change of air pressure. | ||
Pull | Bearing pull is ≧ 800N at axle orientation, there should be no breakage on the housing. | ||
Punching | Bearing pressure of 2000N/250px for 1 minutes, there should be no breakage on the housing | ||
