How to use Huawei commercial optical splitters

Huawei optical splitters are passive devices used to split or combine optical signals in PON/FTTH networks, and they can be installed in racks, trays, or field closures for immediate plug-and-play functionality.

Understanding Huawei Optical Splitters

Huawei optical splitters are passive, bi-directional devices that divide a single optical signal into multiple outputs or combine multiple signals into one. They are commonly used in GPON architectures to share a single backbone fiber among multiple endpoints, such as homes or offices . Splitters come in various ratios, including 1:2, 1:4, 1:8, 1:16, and 1:32, and can be implemented using PLC (Planar Lightwave Circuit) or FBT (Fused Biconical Taper) technologies depending on network requirements .

Installation and Connection

1. Choose the appropriate splitter type and ratio based on the number of endpoints and network design. For example, a 1:4 splitter divides one input into four outputs, while a 1:16 splitter can serve up to 16 endpoints .
2. Mounting options:
   • Rack-mounted splitters (e.g., SPL1202 series) can be installed in a 19-inch rack for central office deployment.
   • Tray-mounted splitters (e.g., SPL9201/SPL9202) are suitable for Optical Distribution Frames (ODF) or Fiber Distribution Terminals (FDT) .
   • Field splitters can be housed in splice closures or pedestals near the customer premises .
3. Fiber patching:
   • Connect the uplink fiber from the Optical Line Terminal (OLT) to the splitter input port.
   • Connect the downlink fibers from the splitter output ports to the Optical Network Terminals (ONTs) at the endpoints .
   • Ensure proper connector types (SC/APC or SC/UPC) are used to minimize insertion loss .
4. Power and operation:
   • Huawei splitters are passive, requiring no external power. They operate by proportionally splitting optical signals without altering wavelengths .
   • In uplink direction, splitters combine signals from multiple ONTs into a single channel for the OLT .

Practical Tips

• Cascading splitters: For large deployments, use multiple splitters in series (e.g., 1:4 followed by 1:8) to efficiently serve many endpoints while minimizing signal loss .
• Signal monitoring: Use an optical power meter to verify signal strength at each output port to ensure proper distribution.
• Environmental considerations: Choose splitters with corrosion-resistant materials (PC+ABS/PPO) for outdoor or harsh environments .
• Backup and redundancy: Some Huawei splitters support uplink backup configurations to enhance network reliability . By following these steps, Huawei optical splitters can be effectively deployed to expand FTTH networks, optimize fiber usage, and ensure reliable high-speed connectivity for multiple endpoints.
