FTTH can provide each access user with access bandwidth of 20M ~ 50M, or even 100M, which can fully meet the needs of the entire broadband popularization speed project; replace the original copper cable with optical cable, replace the electrical signal with optical signal, greatly reduce the network The failure rate also saves the operator's maintenance costs and energy consumption. In addition, its long-distance coverage, 20-year lifespan, safety performance and other factors make no operator d
