Fiber Distribution Box Internal Design

Outdoor fiber optic distribution box are generally multifunctional. In order to adapt to different customer needs, while keeping the external structure unchanged, the internal design generally has three variations.

Frequently Asked Questions on Outdoor Fiber Distribution Boxes

Prolonged exposure to intense solar radiation can cause standard plastics to undergo UV degradation, leading to discoloration, brittleness, and cracking within just 1–2 years. Once cracked, water enters and ruins the expensive fusion splices inside. As a quality-driven optical connectivity manufacturer, all our outdoor fiber termination boxes are molded using a high-grade compound of PC+ABS with integrated UV stabilizers. This industrial plastic blend is heavily field-tested to withstand high-UV indices, ensuring the chassis remains structurally sound and impact-resistant for over 20 years in intense sun-belt regions.

The IP rating defines the enclosure's protection against solids and liquids. An IP65-rated fiber box is water-resistant, protecting against low-pressure water jets and heavy rain from any angle—ideal for standard wall-mounted building setups. However, for severe tropical storms or monsoon seasons in Southeast Asia and coastal South America, we highly recommend an IP68 waterproof fiber distribution box. Our IP68 boxes feature specialized premium silicone gaskets and compression cable glands, enabling the enclosure to withstand continuous submersions and prevent any internal moisture or condensation that could cause signal degradation.

Labor cost and installation speed are critical factors for network contractors. Our FTTH splitter boxes are designed with a highly efficient, dual-layer interior structure. The upper flip-out tray is dedicated to hosting PLC fiber splitters and neat drop cable patching, while the lower compartment isolates the main feeder cable entry and core splice trays. This clear separation allows field technicians to rapidly connect new end-users via pre-terminated drop cables without disturbing adjacent, active fiber lines, effectively cutting truck-roll times by 40%.

Yes, absolutely. As a direct-from-factory fiber connectivity hardware supplier, we offer comprehensive OEM and ODM support to match specific regional bidding frameworks. We can customize the entrance port counts (supporting both mid-span and express ports), provide pre-installed pigtails or adapters (LC, SC, APC/UPC), and alter internal splice tray capacities. Furthermore, we provide options for customized corporate logo silk-printing and specific flame-retardant standard compliant raw materials (such as UL94-V0 rated plastics) to fulfill strict public infrastructure regulations in Europe and North America.

For mass production of outdoor fiber optic distribution box, it will be around 7-10days if no assembly; 15-20days if large quantity order completed with pigtails or splitters.

Yingda is outdoor fiber optic distribution boxes factory, so our price is factory direct price, very competitive. However, in order to help you compete with other, we will offer better price based on your specific requirements and large bulk quantity.
