I also want to add the benefits of FTTH which are:
Multi-parameter scanning enables system designers to study trade-offs with respect to parameters of interest and to choose optimal designs for deployments.
Enables users to analyze different algorithms for electronic equalization.
New BER Test Set enables simulation of milions of bits for direct error counting.
FEC
Interfaces with popular design tools.
Significantly reduces product development costs and boosts productivity through a comprehensive design environment to help plan, test, and simulate optical links in the transmission layer of modern optical networks.
Hope this information will be very helpful to you.
