A fiber optic terminal box is a crucial component in any fiber optic network setup. It serves as the termination point for an optical cable, providing the link between the cable and a pigtail—a device that splits a single fiber optic cable into individual fibers. Mounted on walls, these terminal boxes play a pivotal role in fusing optical fibers together and linking them to pigtails or optical connectors, ensuring optimal fiber management standards.
Key Features
1, Protective Connectivity: Offers protective connections between optical cables and pigtail fibers.
2, Insulation: Ensures insulation between metallic components of optical cables and the cable end shell, facilitating convenient grounding.
3, Storage Space: Provides ample space for housing optical cable terminations and storing excess fiber.
Installation Guide
Connect the pigtail from the fiber optic terminal box to the WAN port of the router.
Connect the LAN port of the router to a switch.
Connect the computer's Ethernet cable to the switch.
Configure the router's gateway settings (typically 192.168.1.1) in the computer's TCP/IP settings.
Access the router's settings through a web browser (e.g., use 192.168.1.1), with default credentials (username: admin) to set static IP, subnet mask, and DNS configurations.
Save settings and reboot the router.
4, Impact Resistance: Features a sturdy housing with sufficient impact resistance for versatile installation scenarios.
5, Installation Options: Supports wall-mounting or direct placement in channels, catering to various installation preferences.
Applications
Fiber optic terminal boxes find extensive applications in local telephone networks, data transmission systems, and CATV (Cable Television) setups. They facilitate indoor cable pass-through, branching connections, and act as protective enclosures for connectors and splices. Constructed from electrostatically sprayed cold-rolled steel, these terminal boxes boast a sleek design and secure core fiber fixation.
In practice, terminal boxes serve as indoor junction boxes, although they are rarely used interchangeably with junction boxes due to distinct purposes:
Distribution Boxes: Used for user-end wiring in both optical and electrical systems.
Splice Boxes: Specifically designed for optical cable splicing and protection against external damage.
Distribution Racks: Serve similar purposes as junction boxes but are deployed in carrier operator facilities.
Core Functions
As the endpoint device in fiber optic line installations, a fiber optic terminal box should fulfill four primary functions:
Fixation: Mechanically secure outer sheaths and core fibers upon entry into the rack, incorporating ground protection and end-point protection.
Splicing: Enable splicing of extracted fibers from optical cables with pigtails, with surplus fibers stored and protected.
Alignment: Facilitate connector insertion from pigtails onto adapters, aligning optical paths for seamless connectivity and testing.
Storage: Provide organized storage for optical connection lines between racks, ensuring neat arrangements and easy adjustments while meeting minimum bend radius requirements.
As fiber optic networks evolve, traditional terminal box functionalities may no longer suffice for new demands. Some manufacturers integrate additional components like splitters, WDM (Wavelength Division Multiplexing) modules, or optical switches directly into fiber optic terminal boxes to meet these evolving requirements.
