Single mode GPON fiber splitter 90 10 1:9 use a PLC chip 1×9 to divide optical signals to 9 channels in unequal splitting ratio from 1% to 100%. Channel no.1 is big split ratio from 50% to 100%, the rest 8 channels are equal split ratio. For example 1×9 splitter 90/10, that means channel 1 is 90%, and channel 2-9 total 10%, and each channel will be 1.25%.

The “90%/10%” in the label indicates that this is an unbalanced splitter. It divides the input optical signal power such that 90% of the power goes to one output port, and 10% goes to the other output port. This is useful in scenarios where different parts of a network require different levels of optical power.
The “1×9” indicates that it is a 1-input and 9-output fiber splitter. It takes a single optical fiber input and splits the signal into nine separate output fibers. This type of configuration is commonly used in GPON systems, which are widely deployed for broadband access networks.
The product components appear to be well-packaged. In the following image, there is a packaged item that is related to the accessories or the splitter itself, presented in a clear plastic package, which helps protect the components from dust and minor physical damage during transportation and storage.
There is a detailed specification included in the package, which contains most of important information of the product splitter 1×9 90%/10%.
