These systems are used in the monitoring of optical fiber networks because increasing security requirements and high expectations regarding the availability of digital services make online monitoring of the optical fiber as a transmission medium more and more of a necessity.
Monitoring systems for small network structures, such as city or enterprise networks, public facilities, and data centers.
The early detection of a malfunctioning fiber makes it possible to react quickly to avoid damage. In addition to fiber malfunction, attempted wiretapping should also be detected and reported.
The SmartOTU from Viavi is a 19" insert with an integrated control system. In the case of an incident, notification will be sent either via e-mail or SMS; further control of the system can be carried out via a web browser or SNMP interface.
It is possible to monitor either a single fiber or – using the integrated optical switch – up to 48 fibers. The wavelength may be selected as desired but typically the system operates with 1625 nm or 1650 nm because these wavelengths do not interfere with network operation.
The SmartOTU does not require an extra PC and is only two height units tall. Expansion is also possible: the modular design can be easily and flexibly adjusted to meet future demands.
The optical network monitoring system (ONMSI) increases the productivity and simplifies the management of optical networks through continuous monitoring of the network.
The network is remotely controlled and permanently monitored for changes and damages, the pathways are precisely recorded and documented via live monitoring. Errors, changes in attenuation, manipulation attempts, damage (caused by rodent bites on the fiber, damaged fibers in the cable, breaks, etc.), and fiber degradation (e.g., in so-called “flooded” sleeves, i.e., water damage) are automatically detected and identified.
Alarms can be configured individually. Continuous (24/7) monitoring via OTDR technology increases security and the reaction time in an emergency. This system is scalable and customizable (Metro/Core/Access). A large variety of measurement modules and optical switches is available. It is possible to configure the alarms for different constellations. In combination with GPS and landmark data, errors can be very precisely localized.
