3.3V / 622 Mbps 1490 Nm Continuous-Mode TX / 155 Mbps 1310 Nm Burst-Mode RX ITU-T G.983.3 B-PON CLASS B 2X5 SFF OLT Transceiver

LT-54B33B series is ITU-T G.983.3 Class B optical line terminal (OLT) for 622 Mbps/1490 nm in downstream and 155 Mbps/1310 nm in upstream. The transmitter section uses a multiple quantum well 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 detector preamplifier (IDP) 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
