If your customer notices a fault,
you are already in the process of fixing it!

FTTH is the most advanced network technology and the future of broadband networks.
Nevertheless, network operators report an error rate up to 30%.

Using Centralised PON Testing will efficiently certify all of your access network as its being built, while reducing future trouble-shooting time by up to 50%!

Provide great service reliability to improve customer satisfaction and reduce maintenance costs.

What is Centralized PON Testing?

“Centralized PON Testing” is a method to test the signal from the hub to the Fiber Termination Unit (FTU) through the splitter. This ensures more rapid and accurate problem diagnosis with faster troubleshooting, using fewer face-to-face customer visits. Centrally testing provides reliability during network build, service activation and whole life operation thanks to a full automatic path, test and verification.

Centralized PON Testing runs completely from the hub to the Fiber Termination Unit and uses a reflector to terminate the fiber. To do this, we use an FBG that is embedded in a fiber coupler and means the reflector can be easily installed during installation, or added later in the outside wall-box.

How does Centralized PON Testing work?

Centralized PON Testing runs completely from the Hub to the fiber termination unit and uses a reflector to terminate the fiber. The Fiber Termination Unit features a Fiber Bragg Grating (FBG) embedded in a fibre coupler tuned to OTDR wavelengths (1645 – 55 nm), which is easy to assemble and flexible with LC/FC/SC-APC/PC connector.

  1. Technician enters the unique id for the PON branch
  2. The OTDR and switch are allocated for this user
  3. Measurement done remotely with Centralized OTDR
  4. Measurements stored in database (Length & Insertion Loss)
  5. If accepted by the technician, the peak is marked as a reference


Centralized Testing cuts downtime!

Benefits of using FIRST METER® Centralized PON Testing:

condition monitoring


  • SLA recording
  • Realtime visibility of network health
Rapid fault diagnosis
& troubleshooting


  • Automatic fault identification
  • Dispatch the right team every time, reducing operating costs even in highly dispersed networks
Simplify bild &
customer identification


  • Simplify build with pre-terminated drop cables, while still uniquely identifing every customer

Centralized testing create great value!

Combine Centralized PON Testing with further concepts of the FIRST METER® family:


Use Extallation to deskill the FTTH connection.

Deskilling the installation saves time for both user and installer, reduces the time spent inside the customer’s premises and allows for the installation to be carried out with semiskilled workers!

Interoperable Gateways

Flexible continue Extallation with DKT Gateways.

DKT Gateways (ONTs) can be flexible combined with our FTUs and are interoberable with third-party OLTs.

Our Gateways (ONTs) are fully upgradeable by the customer up to 10 Gbps.
