Automated fibre network quality
monitoring system
An automated network quality monitoring system (NQMS) helps to maximise the quality of service (QoS) of optical fibre installed in access, metro and long-haul networks.
Exfo Electro-Optical Engineering has launched its automated network quality monitoring system (NQMS) dedicated to maximising the Quality of Service (QoS) of optical fibre installed in access, metro and long-haul networks Revenue generation for network service providers (NSPs) is increasingly dependant on the ability to provide triple- play services to residential subscribers as well as managing critical data services for corporate clients

Chromatic dispersion can be characterised with high accuracy from a single fibre end and testing polarisation mode dispersion from a single end is also possible.
With the need for transmission speed and available bandwidth growing exponentially, these services require a reliable optical network infrastructure.
Consequently, QoS is becoming the key differentiator for NSPs in a very competitive environment, given that enterprise customers are demanding quality guarantees through service level agreements (SLAs).
Similarly, today's residential subscribers typically have an abundance of choices for voice, video and data services.

With pricing becoming more and more comparable, NSPs need to ensure service availability and quality as a key differentiator in order to minimise customer churn as they compete amongst themselves and against cable multisystem operators (MSOs).
Following on the success of earlier Exfo remote fibre test systems (RFTSs), NQMSfibre enables NSPs to monitor their optical fibre plant 24 hours per day, 7 days per week, and pro-actively detect any fibre degradation or precisely locate a fibre cut within minutes.
On the strength of Exfo's expertise in optical time-domain reflectometry (OTDR), the remote test units (RTUs) of the NQMSfibre system combine leading-edge technology with sophisticated capabilities, such as autodiscovery and provisioning functions, to ensure plug-and-play operability within seconds of connecting a new fibre route to the test unit.
A learning algorithm, using statistical processes, greatly reduces or eliminates false alarms and erroneous dispatches.
Implemented on Exfo's NQMS Test Operation Support System (TOSS), which was acquired from Consultronics, NQMSfibre complements existing test applications like NQMSvoice used by carriers for monitoring service quality end-to-end across any type of private or public network for regular telephony as well as Voice-over-Internet Protocol (VoIP) traffic.
The new NQMSfibre solution enables NSPs to automatically or manually test their entire optical networks - either onsite or from a remote location - to accelerate service restoration or prevent outages altogether.
As a result, this next-generation monitoring system helps NSPs consolidate their maintenance activities and reduce operating expenses.
Exfo's NQMSfibre platform is fully scalable, capable of monitoring small, yet critical links as well as ultralong-haul national networks with large numbers of distributed RTUs.
It will be showcased at CeBIT 2007 from 15th to 21st March, 2007 in Hannover, Germany as well as at OFC/NFOEC 2007 from 27th to 29th March, 2007 in Anaheim, CA.
"Exfo has reached another key milestone in its product development strategy", explained Etienne Gagnon, Exfo's Vice-President of Product Management and Marketing.
"Over the years, we have established ourselves as the supplier of choice for optical testing applications in the field as well as monitoring systems for fibre networks, which have been deployed globally".
"The acquisition of Consultronics in 2006 allowed us to apply this expertise to the NQMS platform, used by carriers to ensure network-wide QoS, in order to create a next-generation fibre monitoring solution based on state-of-the-art system components".
