Description
 • The GEPON OLT SFP transceiver is the high performance module for single fiber by using 1490nm continuous-mode transmitter and 1310nm burst-mode receiver. It is optical line terminal(OLT) for ITU-T G984.2. The fiber optical transceiver is compliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA).
 • The transmitter section of the Rollball EPON SFP transceiver uses a 1490nm DFB LD with automatic power control (APC) function and temperature compensation circuitry to ensure stable extinction ratio over all operating temperature range. and is ClassⅠlaser compliant IEC825 and CDRH standards.The receiver has a hermetically packaged burst-mode APD-TIA  (trans-impedance amplifier) pre-amplifier and a burst-mode limiting amplifier with LVPECL compatible differential outputs.
 • The receiver also includes the function of burst mode signal detect output and fast RSSI output which is enabled by a trigger. When the burst optical power is on, the receiver outputs high level; when the burst fiber optic power is off, the receiver outputs low level. Fast RSSI function can satisfy more severe timing demand to monitor the power from any ONU.
