1.	Explain the Split ratios, maximum reach & traffic management as per Classes defined by ITU.
Answer» The maximum permissible optical power attenuation between OLT optical port to ONT input is 28 dB utilizing so called Class B optical network elements. ODN Class A, B, and C are differentiated mainly on the ‘optical transmitter power output’ and ‘bit-rate optical receiver sensitivity. Class A gives the least-optical budget and Class C gives the highest, while cost wise both are in the same order. For maximum 1:64 split ratio, Class B optics are commonly deployed on commercial basis.
