The SFF-OLT-10 is an optical OLT transceiver for IEEE802.3ah 1000BASE-PX20 application. The transmit and receive functions are contained in a standard Small Form Factor (SFF) 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.
