LTW627XB XFP NG-PON2 OLT Transceiver

Gen 2 Class N2 Symmetrical OLT

The LTW627XB-PCA+ is intended for NG-PON2 OLT application in four separate XFP housing. It is a series module and each module is configured with a L-band 9.95328Gbps downstream transmitter and a C-band 9.95328Gbps upstream receiver which work in TDM configuration. The transmitters can be controlled by the LVTTL Tx_DISABLE function and the receivers incorporates the LVTTL Rx_SD output. 

The LTW627XB-PCA+ is the 2nd generation of NGPON2 OLT, which supporting the short preamble configuration. It is designed to support up to 64 subscribers over distances of up to 20km in the ODN. It meets the EEC Directive 2002/95/EC for RoHS compliance.
