SJ-Small-4 48 Cores 2 Port Cable Gland Aerial Joint Closures

SJ-Small-4 48 Cores 2 Port Cable Gland Aerial Joint Closures appears to be a versatile and multi-functional closure designed for different fiber optic deployment scenarios. It can be deployed in aerial, underground, or direct buried environments, making it suitable for a wide range of applications in fiber distribution networks.

Key Features:

Deployment Versatility: The closure is suitable for aerial installations, where fiber optic cables are deployed above ground, as well as underground installations or direct burial, where cables are buried underground.

Fiber Capacity: With the capacity to accommodate up to 48 fiber optic cores.

Fiber Distribution Applications: The joint closures can be used in various fiber distribution network applications, including FTTH (Fiber To The Home) and FTTC (Fiber To The Curve) deployments.

Mechanical Gel Sealing: The closure adopts a Mechanical Gel Sealing type, which provides effective environmental protection for the enclosed fiber optic connections. It helps prevent water, dust, and other contaminants from entering the closure and damaging the fiber cables.

2 Round Port Design: The closure features a 2-port design, with each port capable of accommodating one cable with a maximum diameter of 14mm. This design facilitates easy cable entry and exit, allowing for efficient installation and maintenance.

SJ-Small-4 48 Cores 2 Port Cable Gland Aerial Joint Closures seems to be a suitable and practical choice for fiber optic network installations that require flexibility in deployment environments and a high fiber capacity. However, proper installation practices and adherence to industry standards remain crucial to ensure optimal performance and reliability of the fiber optic network.
