The Single Fiber EPON OLT optical SFP Module 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 IEEE Std 802.3ah™ -2004 1000BASE-PX20. The Single Fiber EPON OLT optical SFP Module is compliant 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 compliant IEC825 and CDRH standards.The High performance GEPON OLT Optical SFP Module has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs.
