How do you manage and maintain your FTTH network equipment and infrastructure?

Only use trained engineers who understand optical principles and have a good work ethic. Use of splitters and avoidance of macrobends is essential to keep losses to a minimum, OLPB are key to ensure reliable connectivity whilst operating 1310nm, 1490nm and 1550nm.

The architecture and components of a typical PON are? 1) Optical Line Terminal (OLT): It is one main device located at the central office. 2) Optical distribution network (ODN): It is the passive part of the network that distributes the optical signals between the OLT and the ONUs. It consists of optical splitters, fibers, and connectors. 3) Optical network unit (ONU): ONUs are located at the customer premises and serve as the endpoint of the PON. There are several different types of PON architectures available. 1) GPON 2)XG-PON 3)XGS-PON 4) NG-PON2

Understanding these unique aspects of PON maintenance and design helps to ensure the reliability and efficiency of FTTH networks: Passive Devices - PONs use passive splitters with no active electronic components, reducing power and maintenance needs. Point-to-Multipoint Topology - PON is a point-to-multipoint system, meaning a single fiber from the provider can serve multiple homes, making it cost-effective. Limited Signal Range - PONs have a maximum range limit (typically up to 20 km) within which they can operate effectively. Shared Bandwidth - The bandwidth in a PON is shared among multiple users, which can affect individual user speeds during peak usage times.

Consider using a BNG for Authentication, Authorization and Accounting on your PON network. Many providers skip this step and leave a wide-open pipe since there is so much bandwidth and little likelihood of congestion. However, upstream capacity planning and good fiscal management are important to a smoothly running business.

Centralized standard OTDR-based solution is blind to see fiber faults beyond the splitter. Or it sees some anomaly but cannot assign it to a drop branch due to so called the parallel path effect. Putting fiber identifiers like FBG-based reflectors helps a bit but it hits the wall again when differential length between such reflectors is lower than the spatial resolution of the OTDR. Moreover, it only allows for recording major faults i.e. faults introducing >3dB insertion loss, after 3-5 minutes of testing, which is unacceptable for preventative monitoring and detection of degradations. It gets even more complex when the in-service PtMP fiber plant is considered also for sensing businesses, where localized sensors are also reflection-based.
