24 Ports: Just-Right High Density
In the Fiber to the Home (FTTH) access layer, 8 ports are too few (limited coverage), while 48 ports are often too many (space-consuming and costly). 24 ports are a very practical capacity option:
Multi-story residential buildings: A six-story residential building with four units per floor can be fully covered by a single 24-port terminal box.
Small commercial areas: Providing dedicated fiber access ports for street-front shops or office buildings.
Continuous coverage in rural areas: A single outdoor pole-mounted equipment room can serve dozens of surrounding rural households.
24 user ports mean that operators can cover a larger area with fewer nodes, thus reducing infrastructure investment while reserving space for future user growth.
IP65 Protection: A "Talisman" for Long-Term Outdoor Reliability
The core value of outdoor junction boxes lies in protection. The GL-FTB-24E-1 is made of high-strength engineering plastic and possesses the following protective characteristics:
IP65 Protection Rating: Completely dustproof and withstands low-pressure water jets from any direction. Internal fiber optic cables and connectors remain secure even in heavy rain or dusty environments.
Individual Rubber Sealing Plugs: Each cable entry point is equipped with an individual sealing plug, ensuring excellent waterproof performance even after cable installation. This design avoids the sealing failure problems commonly found in traditional "shared gasket" designs when multiple cables are inserted.
UV Resistance and Anti-Aging: The engineering plastic housing incorporates UV inhibitors, so it will not become brittle, discolor, or lose strength even after prolonged exposure to sunlight.
Split-Panel Design: Separate Splicing and Termination for Easier Maintenance
Traditional outdoor terminal boxes often have a cluttered internal structure, with splice points and user ports mixed together. During maintenance, technicians may spend considerable time locating the correct points. The GL-FTB-24E-1 adopts a split-panel design, completely isolating the splice area from the terminal area:
Upper (Terminal Area): 24 neatly arranged SC/APC or FC adapters; drop cables can be directly inserted.
Lower (Sponge Area): Independent splice trays and splitter mounting locations for splicing feeder cables to pigtails.
Splitter Expansion Capacity: Can accommodate up to three 1×8 plug-in splitters, enabling a 1:24 split in the PON network.
This partitioned layout allows technicians to troubleshoot or change user connections without touching the splice area, reducing the risk of accidental interference and improving maintenance efficiency.
Safety Lock: Combines Theft Protection with Ease of Use
Outdoor equipment is typically exposed in public areas, making theft prevention crucial. The GL-FTB-24E-1 features a dedicated security lock that effectively prevents unauthorized entry while allowing for easy access by authorized maintenance personnel. This lock operates smoothly even in dusty or salt spray environments.
Flexible Installation: Wall-Mount or Pole-Mount
To adapt to various outdoor environments, the junction box supports both wall-mounted and pole-mounted installation:
Wall-mounted: Suitable for building exterior walls, corridor entrances, or any flat vertical surface.
Pole-mounted: Suitable for utility poles, lampposts, or other cylindrical structures; can be quickly secured using stainless steel straps.
The compact size of the enclosure (requiring no additional equipment room or large cabinet) allows for easy deployment in various space-constrained locations.
Application Scenarios
New Fiber-to-the-Home (FTTH) Residential Buildings: User access points are centrally installed on the exterior walls or at the entrance of each building.
Old Building Renovation: Wall-mounted installations enable rapid "fiber upgrade" coverage.
Rural Fiber-to-the-Home (FTTH): Outdoor pole-mounted installations provide high-density access for scattered rural households.
Small Commercial Buildings: Providing tenants with independent, easily managed fiber optic ports.
Conclusion
The GL-FTB-24E-1 24-Port FTTH Outdoor Terminal Box offers a high-density, high-reliability, easy-to-maintain solution for the FTTH access layer, thanks to its high-strength engineering plastic housing, IP65 protection rating, split-panel design, and flexible installation options. It enables operators to efficiently deploy and manage up to 24 subscriber ports in outdoor environments while ensuring long-term stable operation under sun, rain, and temperature extremes.
For FTTH projects that pursue coverage density without compromising reliability, this terminal box is a trustworthy choice.
