china beijing fiber optic closure with 2 inlets outlets

   china beijing fiber optic closure  with 2 inlets outlets

Optical splice closures are used to distribute, splice, and store the outdoor optical cables which enter and exit from the ends of the closure. There are two connection ways: direct connection and splitting connection. They are applicable to situations such as overhead, man-well of pipeline, embedded situation etc. Comparing with terminal box, the closure requires much stricter requirement of seal. Sealing ring and air valve are required for closure, but that are not necessary for terminal box.

1.Uniformity & high reliability 
2.High quality plastic box body 

3.With the certification RoHs.

(1) Environment Condition:

The Voltage resistance between the metallic elements themselves and between metallic element and the earth is 15KVDC/1min, Non-puncture, no arc-cover.

(3) Optic property:

The curvature radius of the spare fiber is over 37.5mm; no additional optic attenuation.

(4) Seal Performance:

Airproof performance: Airing pressure inside box 100Kpa, pointer immovability after 24 hours or no air bell within 15min when parked in the common temperature water.

(5) Re-encapsulation Performance:

No change in the index of air-proof performance after three times of repeat encapsulation

(6) Mechanical Performance:

After all the following tests, the box and all the components inside don’t change, check through gently or open it if necessary.
