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/10cm for 1 minutes, there should be no breakage on the housing
Impact Bearing impact energy of 16N•m, 3 times of impacts there should be not breakage on the housing
Bending The spot between the FOSC and seal fitting can bear bending tension of 150N at bending angle of ±450 for 10 circles, there should be no breakage on the housing

 

 

 

 

 
Torsion
