In the construction of 5G base stations, in addition to the passive WDM scheme, the semi-active scheme is also gradually applied in actual construction. details as follows:

This solution is suitable for the areas where the power supply of the central office is relatively convenient, and there are two sets of unrouted optical fibers. This solution is gradually becoming the mainstream solution for 5G base station construction.
Solution advantages:
1. The office equipment room uses active equipment, highly integrated WDM and optical protection, and realizes automatic switching between main and standby roads
2. Link optical power monitoring, can even monitor the receiving and emitting power of each optical module (requires OTU board);
3. Support remote network management monitoring and automatic alarm, greatly reducing manual operation and maintenance costs;
4. Simple implementation, no need to change the original network structure, just add fiber;
5. Active equipment is equipped with dual power supplies, which support both DC and AC power, which effectively reduces the equipment failure rate.
Solution shortcomings: Power planning needs to be considered, and the overall equipment cost is relatively high compared to passive solutions.
