Operations

* choose the cable loop with proper outer diameter and let it go through the optical cable. Peel the cable , take off the outer and inner housing, as well as loose contract tube, and wash off the filling grease, leaving 1.1~1.6mfiber and 30~50mm steel core.

* fix the cable pressing card and cable, together with cable reinforce steel core. If the diameter of the cable is less than the diameter of cable loop, first bind the cable fixing point with adhesive tape till the diameter is enough, then fix it.

* lead the fiber into the melting and connecting tray, fix heat contract tube and heat melt tube to one of the connecting fiber. After melting and connecting the fiber, move heat contract tube and heat melt tube and fix the stainless (or quartz)reinforce core stick ,make sure the connecting point is in the middle of the housing pipe. Heat the pipe to make the two into one. Put the protected joint into the fiber-laying tray.(one tray can lay 24cores)

* lay the left fiber in the melting and connecting tray evenly, and fix the winding fiber with nylon ties. Use the trays from the bottom up. After all the fiber has been connected, cover the top layer and fix it.

* position it and use the earth wire in accordance with the project plan.

* sealing the cable retainer nearing the inlet of splice closure and the joint of the cable rings with sealing tape. And close the unused inlets with plugs, with exposed concave parts of the plug sealed with tapes. Then put sealing trips into the sealing groove on the sides of the shell and grease the concave part of inlet of the body between the two parts of the shell. Then close the two parts of the shell and tighten it with stainless steel bolts. The bolts should be screwed tightly with balanced force.

according to the laying requirement, position and fix the hanging tool .

Fiber optic splice enclosures are used to protect stripped fiber optic cable and fiber optic splices from the environment, and they are available for indoor as well as outdoor mounting.

Outdoor fiber optic enclosures are usually weatherproof with watertight seals.

In a typical wall-mounted splice enclosure, fiber optic cable is supported by cable ties, and the cable strenght member is securely fastened to the enclosure’s support. Metallic strenght members must be grounded securely.

The cable jacket(sheath) stops at the splice enclosure’s cable ties. Optical fiber tubes, individual tight buffered fibers, or pigtails are supported by the tube brackets and continue to the splicing trays.

Individual optical fibers should never be exposed outside of a splice tray. Fusion splices or mechanical fiber optic cable splices are contained in the splice trays.

Features:

Large number of cable entry knockouts for incoming and outgoing cables;

Key-lockable main door to prevent accidental opening of splice compartment;

Able to hold up to six MTP loaded cassettes;

Standard accessory kit for cable entry and fibre management included;

Applications:

Ideal for fusion splicing

High fibre density applications

Repairing damaged cables

Suitable for direct termination

Remote cable terminations within building
