24 Cores Waterproof IP65 Fiber Optic Splice Closure with 2 In 2 Out Ports Dome Type

24 Cores Waterproof Fiber Optic Splice Closure 2 In 2 out Dome Type

A fiber optic splice enclosure is a protective housing used to organize, protect, and manage spliced fibers in a telecommunications or cable TV network. It provides a secure environment for fiber splices (both fusion and mechanical) and excess fiber storage (slack loops) at points where cables are joined, branched, or terminated.

Specification:

Features:

1.1 Physical Protection: Shields delicate splices from moisture, dust, chemicals, and mechanical damage (crush, impact, vibration).

1.2 Environmental Sealing: Prevents water ingress, which can degrade fiber performance.

1.3 Fiber Management: Organizes splice trays and slack fiber to maintain minimum bend radius and prevent micro-bends that cause signal loss.

1.4 Access Point: Allows for future re-entry for maintenance, testing, or adding new splices.

Installation:

2.1 Preparation: Select the right enclosure type for the environment (aerial, buried, etc.). Ensure it has enough port capacity and splice tray capacity.

2.2 Cable Preparation: Strip cables to the proper lengths, clean fibers, and secure strength members to the enclosure's strain relief points.

2.3 Routing & Bend Radius: This is critical. Fibers must always be routed with a bend radius larger than the minimum specified (typically 30mm for OSP fiber, 15mm for patch cords). Sharp bends cause signal loss.

2.4 Sealing: Follow the manufacturer's instructions meticulously for sealing cable ports and the main shell. A poor seal is the most common cause of enclosure failure.

2.5 Documentation: Update records with enclosure ID, splice map, fiber identifiers, and test results (insertion loss/IL, return loss/ORL).

Application:

3.1 A 144-fiber feeder cable runs aerially from the central office.

3.2 At a neighborhood pole, an Aerial Branching Closure is installed. Inside, 48 fibers are spliced to 2x 24-fiber distribution cables that run underground. Each underground cable runs to a Buried Pedestal Closure at a street corner.

3.3 Inside the pedestal closure, fibers are branched again via splice trays into 6-fiber drop cables running to nearby homes.

3.4 At the home, a final Small Drop Closure or terminal protects the splice to the pre-terminated indoor cable.
