A fiber broadband provider typically determines and overall split ratio for the network, such as 1x32 or 1x64, and uses combinations of splitters to meet that ratio with each PON port. 1x32 splits were common in North America for G-PON architectures. What Are Fiber Optic Splitters in PON? Fiber splitters are passive devices that divide one optical input signal into. These signals are divided by optical splitters and delivered to Optical Network Terminals (ONTs) at the customer premises. A key challenge is determining how many users a single OLT port can support, which is defined by the split ratio. Traditional GPON networks often employ 1:32 or 1:64 splits.
