What Do You Understand By The Term “split Ratio”? Explain? |
|
Answer» The larger the split RATIO is for GPON, the more economical it is from cost perspective. However, a larger split ratio implies greater optical power and bandwidth SPLITTING, which creates the need for an INCREASED power budget to support the PHYSICAL reach. Split ratios of up to 1:64 are realistic for the physical layer, GIVEN current technology. However, anticipating the continued evolution of optical modules, the TC layer must consider split ratios up to 1:128.
