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

Impact

Bearing impact energy of 16Nm, 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

At least 3 sets sampled each time

At least 3 sets sampled each time

Torsion

Bearing torsion 50Nm, 10 circle at torsion angle±900,

There should be no breakage on the housing.

Temperature circle

Injected air pressure of 60KPa±5 KPa, the temperature circle ranging from -40~+65, 10 times of the circular tests (one circular consists of high temperature for 2 hours + indoor temperature for 2 hours + low temperature for 2 hours + indoor temperature for 2 hours ) when the pressure declines, the amplitude is 5Kpa, immerse the swatch in clean water of normal temperature for 15 minutes, there should be no air bubbles.

Voltage resistance strength

After sealing the FOSC according to the stipulated operation procedures, immerse it in clean water of normal temperature in 1.5m depth for 24 hours, there should be no breakdown or arc over between the metallic components of the FOSC, between metallic components and the ground at DC 15KV for 1 minutes.

Isolating resistance

After sealing the FOSC according to stipulated operation procedure, immerse it in clean water in 1.5m depth for 24h, the isolating resistance between the metallic components of the FOSC, between the metallic components and the ground should be  2×104MΩ.
