Limited Transmission Distance: The range for PON is limited to between 20 to 40 km, whereas an active optical network may reach up to 100 km. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. The GPON network is adopted, and the optical module is class C + (the maximum insertion loss is 32dB).
