"OPGW splice enclosures" and "fiber optic splice trays" are fundamental "OPGW Installation Accessories" for protecting the delicate optical splices:

• OPGW Splice Enclosures: These are robust, environmentally sealed housings (typically IP68 rated) designed to protect optical splices from external elements like moisture, dust, extreme temperatures, and UV radiation, as well as mechanical impact. They are engineered for easy re-entry for maintenance or future fiber additions. They often include secure entry ports for the OPGW cable and a grounding system for the metallic components.

• Fiber Optic Splice Trays: Located inside the splice enclosure, these trays organize and secure the spliced optical fibers and any excess fiber length. They ensure that the fibers are routed within their minimum bending radius, preventing macro-bends or micro-bends that could cause signal loss. Each tray is designed to hold a specific number of fusion or mechanical splices safely.

Together, these accessories create a secure, stable, and protected environment for the optical connections, which are the most vulnerable points of the OPGW communication link, ensuring long-term signal reliability.
