The rapid rate of adoption of technologies like 4G, 5G, xPON, and many more has led to massive increase in the bandwidth requirements of optical transport network. Existing 4G, 5G networks have special requirements in terms of latency, protocol standards, data rates, bandwidth, etc. Laying extra fibers to cater to these network requirements will lead to significant CAPEX and difficulty in fiber management and network monitoring. C-DOT’s Fronthaul System is suitable solution for the above challenges. Based on proven WDM-PON technology, it is easy to install, flexible, scalable, power efficient, O-RAN compliant and will lead to significant reduction in fiber count
