Innovative design is an erect and horizontal type with one hinge on one side and opens on another side. It is the most reliable FOSC in the world. The Fiber Optic Splice Closure is suitable for protecting fiber cable splices in straight-through and branching applications. Based on an advanced formula, the plastic parts are made of injection-molded, high-strength engineering plastic ABS or PC by numerical control equipment; therefore effectively prevent products from aging caused by coldness, heat, oxygen and ultraviolet radiation. The strong housing and main components provide fire resistant, waterproof, and quakeproof while protecting splices during pulling, compressing, and impacting, bending, tensioning, axial tensioning.
Fiber Optic Splice Closure ensures long-term reliability and usage under ambient temperature from -40℃ to +75℃

Application

Fiber Optic Splice Closure is widely used for communication, network system, cabled T.V. of CATV, the fiber optic cable by the network.

 

Fiber Optic Splice Closure

The fiber optic splice closure is common hardware used in the network system. It can mainly be found on the ends of the optical fiber and is used to connect the optical fibers.

It can also be used to protect and organize optical fiber cables from unnecessary damage.

Fiber Optic Splice Closure Material

The fiber optic splice closure is made of metal and ABS/PC/PP plastic, which are not easy to rust and have good thermal stability. The metal has good rigidity and strength, while the plastic has low cost, high intensity, light weight and beautiful appearance. The metal part is usually made of aluminum alloy or stainless steel, while the plastic part is made of engineering plastics such as polypropylene or polyethylene terephthalate (PET).

Fiber Optic Splice Closure Material ABS

The choice of Fiber Optic Splice Closure Material can make all the difference between your project being a success or a failure. The splice enclosures you use should fit within the manholes or pull boxes specified on your project plan. Additionally, the fiber optic splice closures should be labeled per your Project Detail Sheet. Once you’ve selected the type of closure you need, you should install the cables into the enclosure.

Fiber Optic Splice Closure Types

There are two types of splice closures: vertical and horizontal. Vertical fiber optic splice closures are made to withstand outside weather conditions. Outdoor splicing needs high-level seals and waterproof technology. Fiber Optic Splice Closures can accommodate anywhere from a few fibers to 288 fibers. They’re compact and durable, providing maximum protection and are particularly useful for harsh outdoor environments.

Fiber Optic Splice Closure

Another type of fiber optic splice closure is the vertical one. These are known as fiber dome and are similar to the horizontal types. The vertical closure is designed for buried applications and is made of high-quality engineering plastics. The vertical type features one, two, or three inlet/outlet ports. Vertical fiber optic splice closures are typically used for CATV, telecommunications, and fiber optic networks.

Fiber Dome Enclosure

The vertical closure, which looks like a dome. These are often used for burying fiber optic cables in a variety of applications, such as in an aerial FTTH “tap” location. While these closures are ideal for buried applications, they are also suitable for above-ground installation as well. The closure’s cable entrance capacity should match the network’s capacity and the number of cables that are employed in the network.

Fiber Optic Splice Closure Structure

The basic design of most closures involves two main parts: a base or bottom piece, which is attached to a flat surface; and a dome-shaped lid that snaps over the base part.

Bwinners fiber optic splice closure has three parts: the shell, the dustproof cap and dustproof cover. The shell is made of metal or plastic, which is sealed with a rubber ring to prevent dust from entering. The dustproof cap is made of plastic or metal, which can be used for sealing and dust proofing. The dustproof cover can be opened for inspection and maintenance; it can also be closed tightly to prevent dust from entering when not in use.

Fiber Optic Splice Closure Types

Fiber Optic Splice Closure Function

Fiber optic splice closures offer a lot of benefits, which makes them very popular among people.

It protects fiber cables from heat, moisture, corrosion and other external elements.

Vertical fiber optic splice closures

Fiber Optic Splice Closure Application

Vertical fiber optic splice closures come in a variety of configurations, with different inlet and outlet ports. High-capacity models are available for larger networks, and the number of splicing trays can vary. A dome-type fiber optic splice closure must have waterproof technology and a high-level seal to protect the cables from insects. An underground fiber optic splice closure must also keep dirt out.

Fiber Optic Splice Closure

Horizontal fiber optic splice closures are cylindrical or flat, and they meet the same specifications as their horizontal counterparts. They’re usually used in underground or aerial applications. Horizontal fiber optic splice closures are designed to withstand temperature ranges from -40degC to 85degC. A vertical fiber optic splice closure, on the other hand, resembles a dome. Both of these closures serve the same function, but they’re generally used for buried applications.

Fiber Optic Splice Closure Application

The port count in a fiber optic splice closure is a measure of its ability to accommodate multiple types of cables. The number of ports in a closure is important because it indicates how many cables are in the network. The number of ports in a closure will depend on how many cables you need to terminate. Smaller ports are used for drop cables and branch cables, and larger ports are for large cables.
