OLT (Optical Line Terminal), Chinese name is Optical Line Terminal (OLT), mainly installed with the central control station, the transmission rate is TX 2. A GPON optical module is a transceiver used in GPON networks to convert electrical signals into optical signals and vice versa. GPON replaces the traditional three-tier Ethernet design with a two-tier optic network which eliminates access and distribution Ethernet switches with passive optical devices. GPON SFP modules act more like a highway system, with dedicated lanes for the different vehicle types.
