How to install a fiber optic splitter for a telecommunications network

Installing a fiber optic splitter involves careful preparation, precise fiber handling, proper splicing or connectorization, and thorough testing to ensure reliable network performance.

Preparation and Planning

Before installation, conduct a site survey to assess environmental conditions, route planning, and potential obstacles. Verify that all necessary equipment and materials are available, including fiber optic splitters, cables, connectors, cleaning tools, fusion splicer or mechanical splice kit, and testing devices like optical power meters and OTDRs. Implement safety protocols to protect both technicians and equipment.

Fiber Preparation

Measure and Cut: Determine the required fiber lengths and cut them carefully using fiber optic stripping tools. Strip the Jacket: Remove the protective jacket to expose the inner fibers, ensuring a clean cut for secure connections. Clean the Fibers: Use fiber cleaning tools to remove dust or debris, which is critical to prevent signal loss.

Cleaving: Precisely cleave the fiber ends to avoid micro-cracks that can degrade signal quality.

Splitter Installation

Identify Ports: Determine the input and output ports on the splitter; typically, one input fiber and multiple output fibers.

Splice-

Type vs Pre-Terminated: For bare splitters, perform fusion splicing into the network fibers. For pre-terminated splitters, connect using adapters in a fiber distribution box. Placement: Install the splitter in a fiber splice closure, distribution box, or terminal box, securing it with protective slots or clamps to prevent movement.

Fiber Routing: Coil excess fiber carefully and maintain proper bend radius to avoid signal attenuation.

Connectorization and Protection

Attach connectors if required, ensuring clean and precise docking. Use protective tubing or steel encapsulation for outdoor or high-vibration environments. Ensure all latches and clamps are fully secured to prevent fiber movement.

Testing and Verification

Optical Power Test: Measure input vs output power to confirm splitter loss is within specifications (e.g., 1: 8 PLC splitter ≈ 10. 7 dB),. Uniformity Test: Check power variation between output ports (loss uniformity
