Hello, everyone!
In the previous article, I started the topic from the application of FTTH solutions for the 5G transport network. Let me continue writing.

Using the existing FTTH PON networks, mobile operators get:
Coverage. The FTTH network was built to enable the connection of all households, and thus, it means that it will enable the connection of 2,000 connection points per 1 km2.
Scalability. With the increase in the number of 5G network users, an increase in the capacity of the transport network will be required. This is something that is not a problem for PON systems.
Economy. Using existing FTTH PON networks, mobile operators achieve a great economy. The cost of building their transport network is reduced by more than 50%.
Reliability. Existing systems have redundant elements, guaranteeing the reliability of the transport network.
QoS. Current FTTH PON systems guarantee QoS for triple-play services to end users.
Synchronization. Synchronization is mandatory and is supported by the mobile network as well as the FTTH PON system. Mobile transport networks support packet-level and physical layer synchronization, while PON supports efficient time synchronization.

In general, mobile operators for the 5G transport network can choose:
use of leased segments of the PON network - only poles, PVC pipes, optical cables, or dark fibers are rented. This solution doubles the active equipment.
using the same fibers but at different wavelengths. For example, residential users use GPON (1490 nm and 1310 nm), and mobile transport uses XGS-PON or 25/50 GPON (1577 nm and 1270 nm).
use of the PON system as well as other residential users (or similar solutions). The small cells have ONT device (usually SFP ONT), as with residential users.
Several factors affect the total price:
the lease price of optical fibers. It depends on the operator and the number and length of optical fibers. Using the PON FTTH solution reduces the number of fibers required. If the prices turn out to be too high, mobile operators can build their own FTTH solutions and become additional competition to existing fixed broadband operators,
location of CO and MNO hubs, and
the number of small cells that can use the same microwave or optical P2P link.
This is the end of this article. In the next article, I will continue to write about this topic >> 5G and FTTH (3).
Thank you!
