Here, we propose and demonstrate an electro-optic ring modulator on the thin-film lithium niobate platform without compromising between any performances.
One of the optical splitters has a large optical attenuation
The optical splitter with the greatest attenuation is typically a high-ratio PLC (Planar Lightwave Circuit) splitter, such as a 1:64 or 1:128 splitter, due to the cumulative insertion loss from dividing the signal among many outputs.Split Ratio and AttenuationThe split ratio directly affects attenuation: the more outputs a splitter has, the greater the signal loss per output. For example:A 1:2 splitter introduces roughly 3 dB of insertion loss.A 1:32 splitter adds about 15 dB of loss.A 1:64 splitter can reach 18 dB of insertion loss . Higher split ratios reduce the optical power available to each output, limiting the maximum transmission distance and requiring careful network planning.Splitter TechnologiesThere are two main types of optical splitters:FBT (Fused Biconical Taper) SplittersCommon for smaller splits (1:2, 1:4, 1:8).Insertion loss increases with split ratio but is generally lower for small splits.Sensitive to temperature changes, which can slightly affect attenuation .PLC (Planar Lightwave Circuit) SplittersSuitable for larger splits (1:16, 1:32, 1:64, 1:128).Provide uniform and predictable splitting with minimal wavelength dependence.Higher split ratios result in the greatest attenuation, making PLC splitters the choice for large-scale PON deployments .Practical ImplicationsNetwork Design: Using a 1:64 or 1:128 PLC splitter requires accounting for high insertion loss, often necessitating optical amplifiers or shorter fiber runs.Bandwidth Distribution: Higher split ratios reduce per-user bandwidth, so ISPs balance split ratio with service requirements.Distance Limitations: Excessive attenuation from high-ratio splitters limits the feasible distance between the OLT and ONTs . In summary, high-ratio PLC splitters (1:64, 1:128) exhibit the greatest attenuation due to the combination of splitting many outputs and inherent insertion loss, whereas FBT splitters are more suitable for low-ratio splits with lower attenuation.
