FiberFIT Monitoring: advanced monitoring of your fiber optic network

The strength of FiberFit is that network problems become immediately visible in the context of the entire network. Which customers are affected? Are bypasses possible? Do I have multiple failures in this area?

High network availability

FiberFIT Monitoring
This is how it works.

We physically connect monitoring units to the fiber optic network. And we create a link with intelligent software. The units continuously measure glass fibers and send the results to the cloud. The data processing and further control is done online. So, you can do that anytime, anywhere. On any device.

With FiberFIT Monitoring, you always have immediate insight into a possible network problem. What’s more, you can respond and fix it quickly. The result: higher network availability.

The status (monitoring) of the network can be viewed in real time within the software. Connections light up to warn you immediately when there are problems.

Network security

Monitoring, alarm, measurement and degradation analysis.

FiberFIT Monitoring stands for network security. Constant monitoring of your fiber optic network enables timely intervention.

The main functions of FiberFIT Monitoring:

Monitoring and alarm.

Monitoring of fiber optic processes through continuous physical network monitoring and alarm in case of problems.

Monitoring of the physical network, OSI layer 1

Intrusion-detection (tap-detection)

Live Fiber Monitoring

Dark Fiber Monitoring

Notification in case of deviation from threshold(s)

Notification by email, API & dashboard

Flare and control relay contact(s) onsite

Measuring remotely.

Optical test modules continuously measure optical fibers (OTDR). The results are instantly available online anytime, anywhere.

Measurement of length, attenuation and reflection of connected optic fiber(s)

Remote Fiber Test System (RFTS)

Automatic, planned measurement

(Bi-directional measurement with 1 person)

(Unmanned PoP)

Degradation analysis..

By continuously monitoring and analysing the degradation of the fiber optic network, you can prevent problems.

Planned, periodic measurements

Analysis of changes due to e.g. degradation

Automatic triggers

Basis for further analysis; dependence on time, season, bandwidth, etc.

Fiber optic network security. That’s it.

Direct insight

FiberFIT Monitoring:
Benefit on many levels

The technology behind FiberFIT Monitoring is higher mathematics, but we can explain the advantages to you briefly and powerfully.

Efficient physical network monitoring + live dashboards + adjustable alarms = instant insight into the network problem + fast response + short recovery time.

The network owner can guarantee customers a higher availability, without having to use those customers’ equipment to report failures.

Smart link with CoconTheWeb

FiberFIT monitoring continuously measures glass fibers. The results can be sent to CoconTheWeb for data processing. Here you can also manage the client’s asset and maintain its value. CoconTheWeb enriches the FiberFIT Monitoring measurements with an exact location.

Within CoconTheWeb, the disruption is shown exactly on the map. This makes it possible to send service technicians directly to the exact location.

The results are displayed in real time within CoconTheWeb, visually on the map.

Lines light up if there are deviations. The impact of a possible malfunction is clear much faster because it can be seen instantly which customers are affected and whether a bypass is possible.

Cocon is the no. 1 fiber optic registration systems in the Netherlands.

FiberFIT Monitoring benefit per business area:


  • Increase availability of fiber optic network thanks to quicker response time to problems
  • Insight into performances of network administrator and installers
  • Targeted approach to preventive maintenance

Asset management

  • Optical performance of the network is continuously recorded
  • Monitoring of physical network availability independent of an active (or service) layer
  • Detection of optical taps (security breaches) possible
  • Data known by fiber, location or network


  • Approx. 2- to 4-hour time gain per malfunction/solution
  • Knowing the location prevents need to drive to PoP. Malfunction measurement is available immediately.
  • Time gain reduces loss for network owner and their customer(s)
  • More use of network registration system, such as Cocon (investment benefit)
  • Proactive physical network management is now possible (investment benefit)


  • Distance (length of fiber): range of up to 200 km
  • Can be used on both dark and live fiber
  • System only consumes only up to 31W (per local system)
  • Only 2HE (with 1 x 12 switch) 19″ of space required
  • Cloud hardware: VPS, dedicated hosting, 99.99% uptime

Frequently asked questions .

Can FiberFIT Monitoring be applied to lit fiber optic?
Yes, FiberFIT Monitoring uses the ITU-T-recommended monitor wavelength of 1650 nm. Using wavelength multiplexers (WDMs) we connect the optical test modules to the fiber and protect the transmission equipment from unwanted light. We do not use reflectors in the network.
Do I need a server to install software?
No, FiberFIT Monitoring is fully cloud-based. This means that the optical test modules communicate with the FiberFIT Monitoring cloud server. All the processes that monitor your network run on it. You can login to the FiberFIT Monitoring system from any device with a web browser.
Does each optical test module need to be configured locally?
No, all configurations are done centrally, i.e. remotely, via the cloud.
Is my data on the network safe while using FiberFIT Monitoring?
Yes, FiberFIT Monitoring uses secure data centres and its processes are ISO 27001-certified.
What is the maximum distance FiberFIT Monitoring can measure?
FiberFIT Monitoring uses high-quality OTDR (Optical Time Domain Reflectometry) technology. The wavelength used is 1650 nm and the dynamic range is 40 dB. Depending on the number of connectors, welds and other components in a connection, the measuring distance is approx. 160 km.
How can I be informed about a malfunction?
FiberFIT Monitoring alerts and sends alarms via the dashboard and email and can also create SMS, API and other links. With Cocon, an alert is immediately visible in the map material and the malfunction can be followed up on in Cocon.
How is the connection with the cloud created?
The optical test modules have their own 4G connection to the cloud that is part of the FiberFIT Monitoring solution. There is therefore no need for an internet connection besides your own network. It is possible, if desired, because the optical test module has a local ethernet port.
How many fibers can I monitor with an optical test module?
The standard version of an optical test module contains 12 ports to which an optical fiber can be connected. Optionally, a 24-port version is available.
Does Fiber Monitoring also store measurement data of the monitored optic fibers?
All measurement data is stored because it is used for the analysis of optical fiber degeneration. A user can literally scroll through time and see the quality of a fiber optic connection over a period of time. This analysis enables you to detect problems before they lead to an actual malfunction.
What will FiberFIT Monitoring do for me in the short term?
FiberFIT Monitoring reports a malfunction directly linked to a physical location. This enables a repair team to be sent to the right place immediately. Because measurements don’t have to be taken in the field first, this saves valuable hours during the disruption. Connections are therefore fixed faster and thus have a higher availability rate.
