SPL-74H73H series is a small form factor pluggable ransceiver for IEEE 802.3ah-2004 PX-20+ optical line erminal (OLT) with 1.25 Gbps/1490 nm in downstream and .25 Gbps /1310 nm in upstream. It is with the SFP 20-pin onnector to allow hot plug capability. The SPL-74H73H eries is high performance module for single fiber ommunications by using 1490 nm continuous-mode ransmitter and 1310 nm burst-mode receiver. The transmitter ection uses a multiple quantum well 1490 nm DFB laser and s a class 1 laser compliant according to International Safety tandard IEC 60825. The receiver section uses an integrated 310 nm burst-mode detector preamplifier (IDP) mounted in optical header and a burst-mode limiting post-amplifier IC. nlike the conventional BM RX, the SPL-74H73H series does not requires reset pulse to receive optical data packets with different optical power.
