How to use fiber optic splitters?

FBT (Fused Biconical Taper) splitters and PLC (Planar Lightwave Circuit) splitters are both devices used in fiber optic networks to divide an optical signal into multiple outputs. Here’s a breakdown of each type:

FBT Splitters (Fused Biconical Taper Splitters)
 
Technology: FBT splitters are made by fusing two or more optical fibers together and tapering them down to create a single output. This process allows light to couple from the input fibers into the output fibers.
Configurations: Available in various configurations such as 1x2, 1x4, 1x8, and so on, which indicates the number of outputs from a single input.
Insertion Loss: they have higher insertion loss compared to PLC splitters, meaning some signal strength is lost when passing through the splitter.
Uniformity: They may have less uniformity in signal distribution across outputs compared to PLC splitters.
Cost: Typically less expensive to manufacture, making them a popular choice for smaller applications.
Applications:
Commonly used in telecommunications, fiber-to-the-home (FTTH) deployments, and local area networks (LANs).

PLC Splitters (Planar Lightwave Circuit Splitters)
Technology: PLC splitters use integrated optics technology, where the splitter is fabricated on a silicon or glass substrate, allowing for more precise control over the splitting process.
Configurations: Available in configurations like 1x2, 1x4, 1x8, 1x16, and even higher port counts, accommodating larger networks.
Insertion Loss: Generally exhibit lower insertion loss, which helps maintain signal strength over longer distances.
Uniformity: Provide better power uniformity, ensuring an even distribution of signal across all output ports.
Cost: More expensive to manufacture than FBT splitters, but the performance advantages often justify the cost in larger installations.
Applications: Widely used in passive optical networks (PONs), FTTH installations, and telecommunications, where high performance and reliability are crucial.
Both FBT and PLC splitters serve the essential function of distributing optical signals in fiber optic networks. The choice between them typically depends on the specific application requirements, including factors like cost, performance, and network design. FBT splitters are often suitable for smaller networks or shorter distances, while PLC splitters are preferred for larger, more demanding applications where performance is critical.
 
Using an FBT (Fused Biconical Taper) splitter involves a few steps, from installation to connection. Here’s a general guide on how to use FBT splitters in a fiber optic network:
1. Planning and Design
Determine Requirements: Assess how many outputs are needed and the layout of the network.
Choose the Right Splitter: Select the appropriate type of FBT splitter (e.g., 1x2, 1x4, etc.) based on the number of desired outputs.
2. Installation
Location: Choose a suitable location for the splitter, ensuring it is protected from environmental hazards if outdoors.
Mounting: Secure the splitter in an appropriate enclosure or mounting bracket to prevent damage and ensure easy access.
Fiber Preparation: Strip the protective coating off the optical fibers to expose the glass core, ensuring the ends are clean and properly prepared for connection.
3. Connection
Input Connection: Connect the input fiber to the designated input port of the FBT splitter. This may involve using a splice or connector.
Output Connections: Connect the output fibers to the desired devices or networks. Each output port of the splitter will carry a portion of the incoming signal.
Splicing or Termination: Depending on your setup, you may need to splice fibers together or use connectors to attach them to the splitter.
4. Testing
Signal Testing: After connections are made, use an optical power meter and light source to test the signal strength at each output. Ensure the insertion loss is within acceptable limits for your application.
Check for Uniformity: Verify that the signal is evenly distributed across all output ports.
5. Monitoring and Maintenance
Regular Checks: Periodically check connections for signs of wear or damage, especially in outdoor installations.
Cleaning: Keep connectors and fiber ends clean to avoid signal loss due to contamination.
6. Documentation
Record the Configuration: Document the installation, including splitter type, connection points, and any measurements taken during testing. This information can be helpful for future maintenance or troubleshooting.
Safety Precautions
Handle Fibers with Care: Fiber optics can be fragile; handle them gently to avoid breakage.
Use Protective Gear: Wear safety glasses when working with optical fibers to protect against glass shards and ensure proper handling practices.
By following these steps, you can effectively use FBT splitters in your fiber optic network to distribute signals to multiple locations.
