Product Overview

The GL-GPJ09-5601 fiber joint enclosure is a dome series optical fiber splice closure designed to protect fiber splicing points, branch connections, and express cable routes in outdoor optical distribution networks.
The enclosure uses one oval port for loop-through or uncut cable applications and four round ports for branch cable entry. This structure supports direct transmission, cable branching, and fiber protection in FTTH, FTTB, ODN, backbone distribution, and access network projects.
Its mechanical sealing structure uses rubber sealing components, plastic compression screws, and a circular hoop to create a sealed closure without heat-shrink operation. This makes it suitable for field installation where repeat access, spare parts replacement, and controlled sealing performance are important.
Key Features
144 Core Splicing Capacity
Supports up to 144 single fibers with 6 splice trays, making it suitable for medium-capacity outdoor fiber distribution and branch networks.
Express Cable + Branch Ports
One oval port supports uncut / loop-through cable routing, while four round ports support branch cable entry for flexible network expansion.
Mechanical IP68 Sealing
Rubber sealing components, helix pressing, vertical pressing, and hoop fastening help protect the cable joint area in harsh outdoor environments.

FAQ
Q: What is a fiber joint enclosure used for?
A: A fiber joint enclosure is used to protect optical fiber splicing points, cable branch connections, and fiber storage areas in outdoor fiber optic networks.
Q: What is the maximum capacity of GL-GPJ09-5601?
A: The GL-GPJ09-5601 supports up to 144 single fibers or 432 ribbon fibers, depending on tray configuration and project requirements.
Q: How many cable ports does this enclosure have?
A: This model has one oval port for express or uncut cable applications and four round ports for branch cable entry.
Q: What cable diameter is supported?
A: The enclosure is suitable for Φ8–Φ18 mm fiber optic cables. The correct sealing kit should be selected according to the actual cable diameter.
Q: Can it be used for uncut cable branching?
A: Yes. The oval cable port is designed for express cable or uncut cable branching, which is useful for feeder cable routes and distribution branch points.
Q: Is this fiber joint enclosure waterproof?
A: Yes. The product specification lists IP68 protection. Correct sealing kit selection, even compression, and proper installation are required to maintain sealing performance.
Q: What is the difference between heat-shrink sealing and mechanical sealing?
A: Heat-shrink sealing uses heat-shrink sleeves to seal cable entries, while mechanical sealing uses rubber grommets, clamps, screws, or compression parts. This model uses mechanical sealing, which can simplify repeat access and spare-part replacement.
Q: Can this enclosure accommodate a PLC splitter?
A: Yes. The splice tray structure can accommodate one mini PLC splitter if required by the project configuration.
