Validating Quality of Service

As system vendors continuously strive to perfect optical communication equipment, network operator requirements for monitoring and controlling system performance grow. In recent years, numerous applications have emerged where Optical Layer Monitoring is crucial. WISTOM secures your optical communication layer by validating Quality of Service (QoS).

  • Software based analysis – simple configuration and customization


Technical Specification at a Glance


The fastest optical spectrum analyzer on the market. Scans a full spectrum in 40 microseconds

Integrated optical switch provides monitoring of up to 2048 channels in sixteen fibers. Powerful embedded software that performs intelligent analysis of the measured data

Monitors any DWDM system; regardless of system vendor, channel spacing, modulation technology, data format or bit rate

Provides accurate OPM functionality with 100Gbit/s, 40Gbit/s, 10Gbit/s and 2.5Gbit/s in the same link


One Unit Any Application

WISTOM can be applied to complex channel plans containing line grids with variable spacing at both low and very high dense channels. The continuous full-spectrum, real-time channel monitoring of WISTOM ensures an effective scanning of all relevant optical parameters. Thus, the WISTOM unit acts as an all-in-one monitor of any WDM optical network.

Drift Tracking

The increasing complexity in optical communication networks makes it more important to monitor parameter drift. Selected channel quality parameters can be sampled and recorded over time. Thereby, degradations become evident and balancing countermeasures can be applied. Also, performance data can be used to anticipate requirements for network growth/augmentation.


Powerful Software Packages

the wistom network management system

By distributing WISTOM units in critical nodes in your DWDM network and connecting them to WISTOM Network Monitoring System (WNMS) you will get instant access to the optical layer with one software. Key parameters for each monitored channel as well as historical information is easily accessible through an optimized interface.

The WISTOM Software Development Kit (SDK) simplifies your integration of one or several WISTOM units to a customized software application.


The WISTOM Principle

technology description of the wistom principle
  1. A small portion of the signal enters into WISTOM

  2. Signal passes through circulator towards a broadband FBG

  3. FBG is reflecting all wavelengths within C-band

  4. C-band signal enters circulator again

  5. Light is directed towards a scanning filter

  6. An actuator creates an acoustic pulse that locally changes refractive index of the FBG

  7. A part of the signal is reflected in the chirped FBG

  8. The part of the signal that is not reflected is transmitted towards the optical detector

  9. The optical detector receives and stores the data
