Joint Closure Dome

This Fiber Splice Closure is a dome enclosure with 1 inlet and 4 outlet ports for outdoor optical cable in and out, which can hold 144 cores joint. The shell of the fiber optic joint enclosure is of excellent engineering plastics. It features lightweight, high mechanical strength, anti-aging, strong corrosion-resistance; Inside of the OSP fiber splicing closure box can place 6 pcs 24 splice trays for managing splices and excess fibers. The fiber joint enclosure is with good sealing performance, protection up to IP68. The outside plant splice closure is used for direct and branch connection during optical fiber transmission and provides joint connection and protection.
The Fiber Optic Joint Enclosure Box for outside plant OSP integrates the function of distribution, splice, and storage of outdoor optical fiber cable (ofc), and can be used in aerial, duct, pole, wall mounting, underground direct buried fiber optic cable projects.

• In the long-distance transmission and
• local fiber distribution networks
• Fiber To The Home / Fiber To The Curb (FTTH/FTTC).

What is the two main methods of Fiber Optic Splicing for Fiber Optic Joint Enclosure Box?
With fiber-optic connections becoming increasingly mainstream, the ability to accurately perform fiber optic splicing is becoming more and more important. As of now, fiber optic splicing can be carried out using one of two methods: fusion splicing and mechanical splicing.
Before moving forward with a fiber optic installation, it is vital for integrators to have a fairly good understanding of both methods. This would help determine which technique will work best for your company's long-term goals and fit your performance and budget requirements.

This fiber optic splicing technique involves the precise alignment of two fiber optic cables, held in place by a self-contained assembly rather than a permanent bond. A mechanical splice is designed to hold two fiber cables in a way that allows light to pass through seamlessly, with a typical loss of around 0.3 dB or 10%.
In this process, the technician must use an alignment device along with an index matching gel. The gel must have a similar refractive index to enhance the light transmission across the joint, with minimal back reflection.

Mechanical splicing is usually used when splices need to be made quickly and easily, for instance, to temporarily connect cables during installation. That's because mechanical splicing can be easily disconnected if the need arises and you don't require costly apparatus to perform the splice.

The other method to join two fiber optic cables together - and this time we're talking a permanent connection - is fusion splicing.

In this technique, a machine or an electric arc is used to produce heat and fuse/weld glass ends that are precisely aligned together for continuous transmission of light. This translates to a much lower attenuation of around 0.1dB.
Fusion splicing produces a reliable joint with low insertion loss and nearly zero back reflection when done correctly, and thus, is more widely used than mechanical splicing. For example, it's used in long high data rate connection lines that, once installed, are unlikely to be modified.
