Splice Closure & Distribution Box In FTTx Networks

In the rapidly evolving field of telecommunications, Fiber to the x (FTTx) networks are pivotal in ensuring high-speed and reliable internet connectivity. Within this framework, splice closures and distribution boxes play crucial roles.

Splice Closure

A splice closure serves as a protective enclosure, housing spliced fiber optic cables. These closures are critical in safeguarding the delicate spliced areas from external elements such as water, dust, and other environmental hazards, thus maintaining the integrity of the network. Depending on the specific needs, you can opt for various types of splice closures, including Dome, Inline Horizontal, and Inline Clamshell closures, each offering unique benefits.

Distribution Box

Distribution boxes, on the other hand, function as centralized units that facilitate the organization and distribution of optical fibers. They aid in connecting the service provider's network to individual subscribers, thus acting as an intermediary that ensures seamless data transmission. These boxes come equipped with ports that accommodate different numbers of fiber optic cables, simplifying the task of managing complex network architectures.

How to select the Fiber Joint Closure?

  • Application: Identify the specific application for which you need the closure. Is it for aerial, duct, direct-buried, or manhole use?
  • Closure Type: Horizontal closure is often elongated and typically used for in-line splices. Dome (Vertical) Closure is typically used for branching applications.
  • Splicing Capacity: Determine the number of fibers you need to splice. Need to consider future scalability – you might want to have extra trays for future expansions.
  • Sealing Mechanism: Look at how the closure seals – mechanically or heat-shrink. It will ensure the closure is water and dust-proof.
  • Environmental Protection: The closure should be resistant to water, dust, UV radiation, and other environmental factors. Check the IP (Ingress Protection) rating of the closure to determine its level of protection.
  • Installation and Re-entry:Consider how easy it is to install and if it allows for re-entry for future maintenance.

Different Types of Fiber Joint Closure

Type 1: Dome (Vertical) Splice Closure

The Dome (Vertical) Splice Closure is designed to handle high-capacity fiber splicing needs, accommodating anywhere from 24 to a staggering 960 cores. This design is predominantly utilized for expansion and distribution purposes in large network setups, providing a reliable solution for housing numerous fiber cables securely. As a central point of connection, it facilitates organized and safe splicing operations, making it an essential tool in modern telecommunications infrastructure.

Type 2: Inline (Horizontal) Joint Closure

Inline (Horizontal) Joint Closures are crucial in extending fiber connections seamlessly from a primary point to additional signal points. They are available in a wide range of core capacities, spanning from 24 to 144, making them adaptable to various network scales. These closures foster a streamlined pathway for fiber connections, guaranteeing stable and uninterrupted signal transmissions. It's a choice that brings both versatility and reliability to network setups.

Type 3: Inline (Clamshell) Joint Closure

The Inline (Clamshell) Joint Closure is noted for its innovative buckle locking design, a departure from the traditional screw-to-lock mechanisms seen in other inline closures. Designed to accommodate a core fiber range of 24 to 48, it stands as a favorable option for medium-scale projects. This modern approach ensures not only a secure closure but also facilitates easier installation and maintenance access, promising efficiency and user-friendliness in network management.
