How to wire a dual-port optical splitter
To wire a dual-port optical splitter, connect the input fiber to the splitter's input port and attach output fibers to each output port using LC connectors, ensuring proper alignment and avoiding direct exposure to laser light.
Step-by-Step Wiring Instructions
1. Safety First Never look directly into fiber optic ends or connectors, as laser light can cause eye damage. Only trained personnel should handle fiber optic installation and maintenance . 2. Prepare the Splitter
- Identify the input port and the two output ports on the dual-port optical splitter (e.g., 9490OS-D1X2-LC).
- Remove protective caps from all LC connectors before connecting cables . 3. Install the Splitter in a Frame (Optional)
- If using a rack or frame, install the splitter unit in the designated slot. Each dual-port splitter typically occupies two card slots.
- Ensure the rear I/O module is properly aligned with the splitter unit . 4. Connect the Input Fiber
- Take the fiber coming from your optical source (e.g., OLT or central office) and connect it to the input port of the splitter.
- Ensure the LC connector clicks securely into place. 5. Connect the Output Fibers
- Attach the fibers leading to your endpoints (e.g., ONTs or other network devices) to the two output ports.
- Verify that each LC connector is fully seated and aligned to prevent signal loss . 6. Test the Connections
- Use an optical power meter or OTDR to check signal strength and confirm that the splitter is distributing light evenly.
- Each output will experience some signal loss (typically ~3.5 dB for a 1x2 splitter), so ensure the received power is within acceptable limits . 7. Optional Cascading
- If you need to expand the network, you can cascade splitters by connecting an output from one splitter to the input of another. Always calculate cumulative signal loss to maintain network performance . 8. Final Checks
- Secure all cables to prevent strain on connectors.
- Replace protective caps on unused ports.
- Document the connections for future maintenance. By following these steps, your dual-port optical splitter will be properly wired, ensuring reliable signal distribution and minimal loss in your fiber optic network .
