About Fiber Optic Termination Boxes
Fiber optic communication networks have become increasingly popular, largely due to their high bandwidth and data transfer speeds. However, the cables are delicate and require proper maintenance to prevent them from tangling or becoming damaged by external elements such as water or dust. The fiber termination box (FTB) is a key component in this system, and it is designed to protect the cables from these elements as well as provide a convenient way to manage them.
The fiber termination box consists of several parts, including a splice tray, cassettes, and LC or ST-type terminal adapters. It is used to store pigtails or optical cables after fusion splicing, and it can also serve as a point for bunching and rerouting of fiber cables. It is suitable for FTTH applications and can be wall-mounted or pole mounted.
Generally speaking, there are two ways to connect optical fibers: 1) using connectors that mate the two fibers together and 2) using splices, which create a permanent connection between them. Both have their own advantages and disadvantages, so installers should choose the right one for their needs. Moreover, the connectors and splices need to be of the correct style to ensure that they offer good optical performance and strong mechanical strength.
All You Need to Know About Fiber Optic Termination Boxes
There are a variety of different types of Fiber optic termination box. They can be divided into several categories according to the type of cable used, such as multimode and single-mode. They can also be distinguished by the type of termination method: multimode ones are installed in the field on the cable after pulling, while single-mode ones are usually installed by splicing a factory-made pigtail onto the fiber.
A typical FTB is equipped with a splice tray to store the fused fibers. It also has plastic guide posts to help the fiber in the sleeve or transport tube go through them. The splice tray is then clamped at the cable entry hole to keep it in place. In addition to this, the splice box may have additional cassettes for storing extra fibers or pigtails after splicing.
Fiber optic termination boxes are essential components in modern communication networks. These compact enclosures provide a safe and organized environment for terminating, splicing, and connecting optical fibers. They ensure optimal signal transmission by protecting fragile fibers from dust, moisture, and physical damage. Termination boxes come in various types—wall-mounted, rack-mounted, or outdoor—to accommodate diverse installation needs. Equipped with adapters, pigtails, and splice trays, they simplify fiber connections. When selecting a termination box, factors like fiber count, connector types, and environmental conditions must be considered. These boxes play a pivotal role in establishing reliable and efficient fiber optic connections across various applications.
Besides these features, an optical termination box should have adequate safeguards against accidental operations such as cutting and rewiring, which could cause damage to the connector ferrule. It should also be adequately grounded to prevent static electricity from damaging the connectors. Finally, the FTB should be cleaned regularly to avoid the buildup of debris.
There are different styles of fiber termination boxes, including wall-mounted and rack-drawer models. These are designed for indoor and outdoor use and can be either sealed or unsealed. The major difference between these two kinds of FTBs is their design. A wall-mounted FTB is typically designed for direct connection (all splicing, fusion and terminating will be done on site), while a rack-drawer model is usually designed for cross-connect architecture with adequate space for splicing, distribution and termination.
