Fiber distribution Cabinet

The HLGXF(04) fiber optic distribution cabinet is engineered for outdoor use, providing secure housing for splicing, distribution, and management of fiber optic cables. It features a corrosion-resistant composite shell, a single lockable side door, integrated splicing & distribution modules, and excellent sealing performance to meet IP53 waterproof and dustproof standards. Available in multiple sizes and capacities, it’s suitable for a wide range of network applications.

1. Features

• The shell of this equipment is made of high intensity, anti-corrosive, anti-aging special composite material. It can effectively prevent rain, snow, insects and corrosive gases and other environmental impact.
• Structural design is reasonable, using single-side and single lockable door. There is a large space in the cabinets. It’s easy to operate and maintain.
• Have grounding device.
• Give full consideration to fix, earthing and welding cable, to coil the redundant cable. It’s very convenient for connecting and scheduling the cable.
• Internal optical path clearly marked, welding, coiling position clear.
• Compact structure, easy installation and excellent sealing performance.
• Using splicing & distribution integration module with fusion, connection and storage in integration. It’s available for different adaptors such as FC, SC, LC type. Adaptors assembling with deflexion of 30° to ensure fiber pigtail bending radius and to avoiding the light direct the eyes when operating.
• Can integrate splitter, WDM.
• For ribbon and non-ribbon cable.
• Meet UL94-V0 standard.

3.Installation and Commissioning

  Installation：

• Supporting base installation
• When the supporting base is installed, use 4pcs M12×100 expansion screw to fix.
• After installing the cabinet, debug it. The activities segment should be rotating flexible, plug reliable and easy to maintain. The assembly should have the consistency, solid non-loose, and then place reliable.

  Usage and maintenance

• The cable comes into the cabinet through the bottom holes. Start to strip 600mm cable away from the bottom of the box 50
• Fix the cable at the lead-in module in the bottom of box.
• The main cable comes into the integrative module, and then splice with the pigtail in it.
• The structure of the integrative module is like a drawer. Draw out the module when splicing. After operating, push the module back. When you push it in the end, the unit will automatically lock. Each integrative module can be put 12 pcs FC or SC adaptors or 24pcs LC adaptors, while welding 12-core optical fiber.
• The record sheet will be stick on the cover of each module. Make the record after finishing operating.
• In the box, connecting and scheduling the fiber optic lines will come true via the patch cords in different length.

4. Capacity

HLGXF（04） mainly make up of the box, coil tray, splicing & distribution integration module, adaptor, pigtail and splice tray and so on.

 6. Package:

With moisture-proof and anti-vibration measures. All the attached accessories will be put into a bag and then put into the box. The whole equipment will be sealed by a good quality carton.

7. Storage:

It’s not appropriate to put the heavy goods at the top of the box. The air should be consistent with the requirements of the environmental protection. Indoor temperature is -40℃ ~ 45℃ and the relative humidity is less than 95%.
