GPON OLT SFP 20km Optical Transceiver Module

EOLS-GET-20G series is a small form factor pluggable transceiver for IEEE 802.3ah-2004 PX-10+ optical line terminal (OLT) with 2.5 Gbps/1490 nm in downstream and 1.25 Gbps /1310 nm in upstream. It is with the SFP OLT 20-pin connector to allow hot plug capability. The EOLS-GET-20G series is high performance module for single fiber communications by using 1490 nm continuous-mode transmitter and 1310 nm burst-mode receiver. 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 require reset pulse to receive optical data packets with different optical power.
