Product Description The GPON-OLT-20 transceiver is the high performance module for single fiber by using 1490nm continuous-modetransmitter and 1310nm burst-mode receiver. It is optical line terminal(OLT) for ITU-T G984.2. The optical transceiver iscompliant with the Small Form- Factor Pluggable (SFP) Multi-Source Agreement (MSA). The transmitter section 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 Class I lasercompliant 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 atrigger. When the burst optical power is on, the receiver outputs high level, when the burst optical power is off, the receiver outputs low level. Fast RSSI function can satisfy more severe timing demand to monitor the power from any ONU. Product Feature Single Fiber Transceiver with single mode SC receptacle 1490nm continuous-mode transmitter with DFB laser 1310nm burst-mode receiver with APD-TIA Single 3.3V power supply Reset burst-mode receiver design Burst mode signal detect output which is LVTTL compatible. Burst mode received signal strength indication (RSSI) output Complies with ITU-T G984.2 Class C+ Digital diagnostic interface compliant with SFF-8472 Rev 9.4 , Complies with RoHS directive (2002/95/EC) Operating case temperature: Standard: 0 to +70C
