The Applications And Benefits of Splitter Distribution Box

Today, we are going to focus on knowing the basics of the splitter distribution box and its benefits. The continual expansion of broadband networks and the resulting set up of fiber to the home (FTTH) infrastructures make network organizers adopt powerful management and planning systems of which fiber splitter distribution box is a small part.

What is Splitter Distribution Box?

Here it mainly referring to PLC splitter distribution box, which is a kind of fiber termination box. It is often used in FTTH applications for jointing feeder cable and drop cables through optical splitters; And it can distribute cables after installing splitters and also can draw out room fiber optic cables through direct or cross-connections. It is suitable for fiber terminal point to complete connection, distribution, and scheduling between perimeter fiber cables and terminal equipment, especially suitable for mini-network terminal distribution. They are of high strength plastic and waterproof, Therefore, They can be widely applied in FTTH indoor and outdoor terminal applications.

The fiber splitter distribution box offers a cost-effective way for the FTTH access network. According to the PLC splitter configuration types, there are two common types: plug-in type PLC splitter and steel-tube PLC splitter termination box. Here we start to make a simple introduction:

Cassette PLC Splitter Termination Box

This type can accommodate plug-in type PLC splitter with different configuration types such as 1×8, 1×16, 1×32, and 1×64. If loaded with fiber pigtails and adapters, this termination box can offer a one-stop cable distribution solution. It is of ABS+PC; normally it has two layers, the upper is for light splitting, the lower is for splicing.  As it is with clear cable incoming and output port, the FTTH splitter box is convenient for installation, maintenance and subsequent termination.

Steel-tube PLC Splitter  Termination Box

In general, this type of fiber cable termination box can accommodate 1×4, 1×8, and 1×16 steel tube PLC splitters. It is suitable for wall and pole mount installation, which comes with 1-3 input ports, 8-24 outlet ports, and holds a max of 24 subscribers. They have the function of the mechanical splice, fusion splice, light splitting, cable distributions, etc. Besides, the quantity of pigtail and adapters loaded inside this optical fiber cable distribution box can also be installed flexibly as need.

Its Features and Benefits

The optical splitter box enables internet service providers to accelerate their deployments more effectively and ideal for deploying networks in FTTH applications. And it also offers increased efficiency within distinct FTTX network applications. Featuring a compact solution for wall mounting, these termination boxes provide significant space savings while maintaining hand access to connectors. Below are the features and benefits:

. Provide a small footprint for splitting, splicing, and terminating and are environmentally rated IP65 for indoor or outdoor use.
. Each box can equip with splice tray that allowing for fiber splicing and joint.
. Accept standard splitters and splitters can be easily added after the termination enclosure has been installed; it can accommodate 1×4, 1×8, 1×16, 1×32 fibers, up to 64 fibers.
. Its small size and flexible mounting options offer easy integration into cell sites and huts; providing on-demand capacity for wireless backhaul applications.
. Offer an economical solution for applications where larger-sized FDHs (fiber distribution hubs) may be unfeasible.


The optical fiber cable distribution box provides a cost-effective solution for the FTTH network. Currently, some manufacturers supply this type of box with loaded fiber splitters, adapters, splice trays, or pre-terminated pigtail assemblies, which help reduce operation time and cost and satisfy different customer fiber optic solution requirements.
