How to use a Huawei gigabit optical splitter

A Huawei gigabit optical splitter distributes a single fiber input to multiple outputs, connecting your main FTTR or ONT device to sub-devices while maintaining gigabit speeds.Understanding the Huawei Optical SplitterHuawei gigabit optical splitters, such as the ATB2121-S-5U-SC/APC, are passive devices that split one optical input into multiple outputs, typically in a 1:4 ratio. One input connects to the Main FTTR or ONT, while the outputs connect to Sub FTTR devices or additional splitters for cascading, supporting up to 16 endpoints in total . These splitters are pre-terminated with SC/APC connectors, so no fiber splicing is required .Installation StepsPlacement: Mount the splitter in a secure location, such as a wall or rack, ensuring it is protected from physical damage and excessive bending of fibers .Connecting the Input:Connect the uplink fiber from your Main FTTR or ONT to the splitter's input port using the SC/APC connector .Ensure the connector clicks securely to avoid signal loss.Connecting the Outputs:Connect each output port to a Sub FTTR device or another splitter if cascading is needed .Use the ATB box to store excess fiber length and prevent bending or damage .Cascading Splitters:If more than four sub-devices are required, use the cascade port on the first splitter to connect a second splitter, effectively expanding the network to 16 outputs .Fiber Management:Use plane corner clips, wall-through cable supporters, or external/internal corner clips to secure fibers along walls and corners, preventing stress on the connectors .Operational NotesPassive Device: The splitter does not require power; it simply divides the optical signal.Signal Loss: Each split introduces some attenuation, so plan splitter placement to minimize long fiber runs and maintain gigabit performance .Compatibility: Ensure the splitter is compatible with your Huawei FTTR version (F50 Standard or Plus) or GPON ONT devices .Testing: After connections, verify that each Sub FTTR or ONT device receives a stable gigabit signal. Check LEDs on the devices to confirm proper registration and data transmission .SummaryUsing a Huawei gigabit optical splitter involves connecting the uplink fiber to the splitter input, distributing outputs to sub-devices, managing excess fiber, and optionally cascading splitters. Proper placement, secure SC/APC connections, and careful fiber management ensure stable gigabit connectivity across all endpoints in your home or enterprise network .
