Splitters divide signal, causing major loss. Example: Total attenuation = Fiber Loss + Splice Loss + Connector Loss + Splitter Loss 👉 Total Loss = 18 dB This must be within GPON limit (~28 dB). High attenuation leads to: That's why link budget planning is critical. Optical splitters play an instrumental role in the Passive Optical Network (PON), enabling a single PON interface to be shared amongst multiple subscribers. Traditional GPON networks often employ 1:32 or 1:64 splits. The real design trade-offs lie in how you split the optical signals, where you locate the splitters, and the ratio you choose for subscriber sharing. Let's dive into the key considerations. In the case of splitters, attenuation is inherent to their division function: by dividing the signal among multiple outputs. Instantly compute insertion loss, power at each subscriber port, and fade margin for PLC and FBT splitters — including dual cascade configurations. Covers GPON (1490 nm / 1310 nm), EPON, and RF video overlay (1550 nm).
