Atmospheric pressure: 70kpa ~ 106kpa

Insulation resistance: the insulation resistance between the high-voltage protective grounding and the case is greater than 20000m Ω / 500V (DC)

Withstand voltage: the withstand voltage between the high-voltage protective grounding and the case is greater than 3000V (DC) / 1min, without breakdown and flashover.

External cable fusion, wiring into the end, pigtail storage, pigtail fixed, according to the user's requirements, micro optical splitter can be selected to achieve the light splitting function.

Maintain

1) The cable shall be connected according to the specified wiring, and each wire shall be firmly connected during connection, and the cable shall not be loose and float in the box;

2) Cable routing should be orderly, reasonable and avoid crossing;

3) The optical fiber should keep free bending in the box, and its curvature radius should be greater than 30mm;

4) When operating the optical fiber, be careful not to puncture the skin and eyes;

5) After the optical cable is stripped and welded, the grounding wire shall be used nearby for grounding;

6) After the construction, the box door should be closed and locked.

Marking, packaging, transportation and storage

1) The packaging and transportation of the equipment box shall meet the industry standard. The storage shall be free of acid, alkali, sulfur compounds and other toxic gases in a ventilated and dry warehouse, and open storage is not allowed;

2) The package is packed according to the product packaging specification, with moisture and dust-proof measures. Accessories and spare parts are packed in separate bags and then put into the packaging box. The box is sealed with film and external carton. The carton is painted with rainproof, moisture-proof and direction signs;

3) Transportation: this box can adapt to the transportation of various means of transportation. During the transportation of packaged products, the ambient temperature is required to be between - 40 ℃ and 60 ℃, and the relative humidity is not more than 90%. The product shall not be exposed to rain, soaking or sunlight when the temperature is above 40 ℃. Loading, unloading and handling shall be carried out according to the transportation operation marks painted on the package, and the products are not allowed to be placed upside down, side placed or turned over;

4) Storage: no heavy articles should be accumulated above the box. Acid, alkaline or other harmful gases in the air of the warehouse should meet the requirements of environmental protection regulations. The indoor temperature is between - 25 ℃ and + 55 ℃, and the relative humidity is not more than 95%.

Fiber termination box contains the shell, the internals (supporting frame, set fiber disc, fixing device) and optical fiber joint protective element. Prominent advantages of fiber termination box lie in efficient cable-fixing, welding and its protective role in machinery of the optical fiber.

A insulation is always demanded between cable metal components and cable terminal box shell in a fiber termination box, which provides space for cable terminal and remained fiber storage. In addition, fiber termination box also facilitate the installation of different occasions since it is easy to access, which turns out to be time and cost saving.

Application

Fiber termination box is universally used in telephone, agricultural telephone network system, data and image transmission system, CATV cable television series, indoor cable through force access and branch connection. Fiber termination box is available for the distribution and termination connection for various kinds of fiber optic systems, especially suitable for mini-network terminal distribution, in which the optical cables, patch cores or pigtails are connected. In addition to that, fiber termination box can be applied to joint fiber pigtail, protect fiber optic splices and share out the connectivity to individual customers.
