Fiber Optic Splitter Termination Box for FTTH Applications

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. Fiber optic splitter termination box is a small part of this system. Today, this post mainly focuses on the basics of splitter termination box and its benefits.

Fiber Optic Splitter Termination Box Overview

Fiber optic splitter termination box, here mainly referring to PLC splitter termination box, is a kind of fiber termination box. It is often deployed in FTTH applications for connecting feeder and distribution cables through optical splitters. And it can distribute cables after installing splitters and also can draw out room fiber optic cables in direct or cross-connections. The splitter termination box 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. Therefore, it is widely applied in FTTH indoor and outdoor terminal applications.

Common Types of Splitter Termination Box

Fiber optic splitter termination box offers a cost-effective way for the FTTH access network. And there are different types in the market. According to the configuration types of PLC splitter, there are three common types of splitter termination box: plug-in type PLC splitter termination box, blockless PLC splitter termination box and ABS PLC splitter termination box. Here is a simple introduction to them.

Plug-in Type PLC Splitter Termination Box

This type of PLC splitter termination box 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-step solution for cable distribution. This box is usually made of SPCC. And it has two layers. One is for light splitting. Another is for splicing. With simply and clearly arranged incoming and outgoing cable management, the box is convenient for installation, maintenance and subsequent termination.

Blockless PLC Splitter Termination Box

Generally, this type of termination box can accommodate 1×4, 1×8 and 1×16 blockless PLC splitters. It is suitable for wall and pole mount with 1-3 inlet ports, 8-24 outlet ports, and up to 24 FTTH drops. They have the function of mechanical splice, fusion splice, light splitting, wiring distributions, etc. Besides, the quantity of pigtail and adapters that are loaded inside this termination box also can be matched flexibly.

Like the two types of PLC splitter termination box mentioned above, this ABS PLC splitter termination box can accommodate 1×32 and 1×64 ABS PLC splitter. And its box has two cable ports, 10-14mm cable diameter capacity and three splice trays in maximum. Capacity of main backbone cable is 12 simplex fibers. It is suitable for corridor, basement, room and building’s outer walls application with the function of mechanical splice, fusion splice, light splitting, wiring distributions.

Apart from the classification listed above, fiber optic splitter termination box also can be classified in terms of the capacity of ports such as 1×4, 1×6, 1×8, 1×16, etc.

Features and Benefits

Fiber optic splitter termination box enables service providers to accelerate their deployments more effectively and is an ideal solution when deploying networks in FTTH applications. And it offers increased efficiency within distinct FTTX network applications. Featuring a compact solution for wall mounting, these termination boxes provide a significant space savings while maintaining hand access to connectors. Following are the features and benefits of deploying fiber optic splitter termination box.

  • Provide a small footprint for splitting, splicing and terminating and are environmentally rated for indoor or outdoor use.
  • Available in several types, each box can equip with splice tray allowing for an input splicing option.
  • Accept standard splitters and splitters can be easily added after the termination box has been installed. And 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 back haul applications.
  • Offer an economical solution for applications where larger sized FDHs (fiber distribution hubs) may be unfeasible.
Summary

Fiber optic splitter termination box provides a cost-effective solution for FTTH applications. Nowadays some manufacturers provide this type of box with pre-installed fiber splitters, adapters, splice trays or pre-terminated pigtail assemblies, which help to reduce installation time and cost and satisfy different requirements of customers.

Fiber Termination Box – Solution for FTTH Network

In the FTTH network, cable management is a real task. In order to transmit signals to multiple terminations, large amount of optical pigtails are used in the cabling system. A solution must be found to solve the problem of cable routing. Luckily, the advent of fiber termination box has efficiently handled the crux by accommodating and protecting the fiber cables.

Specifically, fiber termination box (FTB), namely optical termination box (OTB), is a kind of fiber optic management product used to distribute and protect the optical fiber links in FTTH Network. Owing to its compact and small size, it is also considered to be the mini version of fiber optic patch panel or optical distribution frame (ODF). The number of ports in fiber termination box is varied from 8 ports to 96 ports, you may choose the right box according to your cable needs.

Fiber Termination Box Types
  • Wall Mount vs. Rack Mount

In terms of different designs, fiber termination box can be classified into wall mount and rack mount types. Wall mount fiber termination box is a perfect solution to be used in building entrance terminals, telecommunication closets, main cross-connects, computer rooms and other controlled environments. It is a suitable device for pre-connectorized cables, field installation of connectors and field splicing of pigtails.

Rack mount fiber termination box is designed for cross-connect and interconnect architecture which has interfaces between outside plant cables and transmission equipment. And the box unit provides space for fiber splicing, distribution, termination, patching, storage and management.

  • Indoor vs. Outdoor

With regard to wall mount fiber termination box, it has another two classifications of indoor and outdoor types. Obviously, this is categorized according to the installation site. As the transition point between the riser and the horizontal cable, indoor wall mount fiber termination box offers the operator with optimal flexibility. It serves as the storage place for extended and terminated fibers or as the splice point for spliced fibers.

Outdoor wall mount fiber termination box is also used for fiber splicing, termination, and cable management. But its enclosure is usually sealed to prevent cables from environmental damages in FTTH network.

Applications

Fiber termination box is typically applied to telecom equipment room or network equipment room. It is also available for the distribution and termination connection for various kinds of fiber optic systems, and is especially suitable for mini-network terminal distribution in which the optical cables, patch cores or pigtails are connected.

Distinctions Between Fiber Termination Box and Fiber Splice Tray

Sometimes, people may mix the fiber termination box with fiber splice tray due to the similar inside structure. Besides other applications, fiber termination box is often used as the terminal junction where a single cable is spliced into multiple optical pigtails that have connectors at one end and no connector at the other end. Sometimes, fiber splice tray is inside the fiber termination box to contain the spliced fibers. But it can also be employed for independent use to protect the spliced fibers. Thus, these two devices are not interchangeable.

Conclusion

In conclusion, fiber termination box is an important device used for protecting and distributing optical fiber links. The utilization of fiber termination box greatly eases the stress of cable management in FTTH network. Wall mount both indoor and outdoor FTBs and rack mount FTBs are widely deployed for optical communication infrastructures. Of course, a right selection will also contribute to your network.
