OTDRs are commonly known to network operators as portable units, but EXFO also integrates them in rack-mount equipment along with optical switch and controller units. These are used to perform on-demand troubleshooting of any fiber connecting to the equipment, whether it transports live traffic or not, and whether it is connected permanently or temporarily. Routine maintenance tests can therefore be scheduled and automated to dramatically simplify this process.
EXFO offers various optical testing instruments and system configurations to help you reduce support- and maintenance-related expenses. Here are some of the available configurations and options:
With an OTDR set in one location, shared among your technical staff and also accessible through other systems, you can change the way you support your network and your customers. Web access is standard on all EXFO platforms; from any location and from any computer linked to a VPN in your corporate network. You are therefore able to perform OTDR testing or define and start a preventive test cycle to identify recurrent issues on your fiber network.
In addition to boosting the efficiency of your technical workforce, you can speed up link failure root-cause analysis and save two to five hours per event, therefore accelerating time-to-repair with better-quality information about the nature and location of the reported fiber/cable fault.
Other benefits and applications include:
Remote Fiber Testing and Monitoring using OTDRs has never been simpler.
This poster showcases the solutions within fiber network monitoring and management portfolio, such as standalone solution (Fiber Guardian), centralized server solution (NQMS fiber) and central diagnosis in FTTX solution (FG-750 Node iOLM). Discover their unique set of features that includes trend reporting, bidirectional communication, and more.
In this article, EXFO demonstrates its innovation in applying its CWDM OTDR technology to ﬁber-monitoring application.
This article discusses application and use of classical OTDRs for remote control of submarine cable installation and fault managementrelated activities; it also presents an out-of-the-box monitoring and remote test solution.
Bandwidth demand is growing faster than ever.. In a context of high pressure on cost and decreasing level of optical expertise in the field, FTTx/PON network testing is a necessity, and this, throughout all stages of the network lifecycle.
When it comes to high-speed transmission, especially when transmitting at 10G, 40G/100G, assessing fiber quality is a must. Once the basic parameters (i.e., loss, ORL, etc.) are under control, the next step is to qualify the fiber and to ensure that it is fit for transporting actual customer traffic. Polarization-mode dispersion (PMD) and chromatic dispersion (CD) optical testing become crucial at high speeds.
As bandwidth demands continue to increase, network service providers are looking at 40 Gigabit Ethernet and 100 Gigabit Ethernet networks to accommodate the ongoing traffic surge.
Packet traffic on submarine networks is steadily on the rise and submarine network operators must meet exacting services while optimizing performance.
