3.3V, 1.25 Gbps 1490 Nm Continuous-Mode TX / 1.25 Gbps 1310 Nm Burst-Mode RX 2X5 SFF Package, GE-PON OLT Transceiver (IEEE 802.3ah-2004 1000BASE PX20)

LT-74E73E is an optical transceiver for optical line terminal (OLT) for IEEE 802.3ah-2004 1000BASE-PX20 applications. The LT-74E73E is high performance module for single fiber Communications by using 1490 nm continuous-mode transmitter and 1310 nm high sensitivity burst-mode receiver with settling time less than 400 ns. The transmitter section uses a 1490 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated 1310 nm burst-mode Avalanche photodetector preamplifier mounted in an optical header and a burst-mode limiting post-amplifier IC. Unlike the conventional BM RX, the RX does not requires reset pulse to receive optical data packets with different optical power. LVPECL Interface is used for differential inputs and outputs. A LVTTL Logic Interface simplifies Interface to external circuitry. By optoway
