The SFP-OLT-XX is an optical OLT transceiver for IEEE802.3ah™ -2004 1000BASE-PX20 application. The transmit and receive functions are contained in a standard Small Form Plugable (SFP) package with a single fiber interface terminated with a standard SC or other optional connectors with high return loss. The transceiver is the high performance module for 1.25Gbps data rates.
The transceiver comprises a 1310nm Burst Mode optical receiver and a 1490nm Continuous Mode optical transmitter. The transmitter utilized a multiple quantum well 1490nm DFB laser is compliant with Class laser safety standard IEC-60825. The receiver uses an integrated 1310nm APD and preamplifier mounted in an optical header and limiting post-amplifier IC.
The transmitter incorporates an Automatic Laser Power Control circuit to maintain the optical power and extinction ratio over an ambient temperature of 0 to +70. Included in the module is a Transmit Disable input and a Transmitter Fault Indicator. The transmitter data inputs and receiver data outputs are LVPECL compatible.
