Airtel asking 50k for xstream fiber.

The PON standard work on auto-discovery and TDD basics.I think it is possible to have two different olt providing connection over same fiber strand but the bandwidth will be halved.
Each PON device have specified time to listen and send data.Thus,if two OLT are there and configured to work together,it can be done but total maximum bandwidth will take considerable hit.
For EPON,1gbps throughput will be halved.But, since EPON support variable packet size data and maximum bandwidth is not always utilised,it could work without significantly hurting any of the connection.
Maybe,but this is usually not used since most isp are rich enough to lay fiber seperately,and never share infrastructure,leading to stupid and unrequired investment capping the investment on equipments and international transit.

I've seen LCOs using multi core fiber cables to from different pon ports of the same olt to provision connections.
They use different strands for different areas, yeah ethernet standards are quite flexible and the cheaper cost of EPON pushes LCOs to get epon olts.
I know that it can be done but now one will do it because of too much work and the performance penality.
