What is the difference between Full-band PLC splitter and three FBT window splitter?

Due to the working principle and the limit of process, traditional FBT splitter can generally meet the transfer at most three different wavelength, which is called the three window splitter. While the loss of PLC splitter is very low in a very wide wavelength range (1260-1650nm), so in addition to meet the three a window outside the commonly used, PLC splitter can also be used for transmission and management more work wavelength. So PLC splitter is called full-band splitter. The wavelength requirements of EPON and GPON standards were 13101490 and 1550nm, the next generation PON standard (such as WDM-PON) will require more work wavelength. The use of PLC optical branch devices can better adapt to the needs of future network upgrade and development.
