@mayank yadav this ONU was provided by the vendor (LCO) themselves and not by BSNL. It is a small device, looks like mini Jio Fiber box white coloured square box. It is a
Digisol brand model DG-GR1010 and is a
GEPON and not
GPON device - so not sure if that will have any compatibility issues depending on LCO implementation of FTTH rollout in area to area.
MRP of the device is Rs. 3k but I saw it on
Amazon.in for around 1.6k recently.
