Affordable — Monitoring at your own pace
Remote, stand-alone unit
Fiber Guardian is an entirely stand-alone OTDR remote test unit, designed to enable you to start monitoring critical fibers without the larger investment required for a client-server RFTS application.
If any of these situations applies to you, Fiber Guardian is the ideal solution:
- Must fulfill stringent support-level agreements that require a restoration time of less than a few hours or network/service availability of 99.99% or higher.
- Need to measure and improve contractor efficiency throughout the restoration process.
- Having difficulty finding qualified personnel for on-site troubleshooting.
- Want to begin investing progressively, starting with the most vulnerable part of your network.
No Commitment, no hassles
Fiber Guardian is a plug-and-play solution that is simple enough for beginners, and powerful and flexible enough for your experts. The unit doesn’t involve any additional infrastructure—no server, no external PC—only minimal software maintenance is required. You can access it remotely from virtually anywhere by simply using your personal login user name and password, as with any secured server on your LAN or through a dial-up connection. There is no need for third-party remote-access tools such as Virtual Network Computing (VNC) servers or pcAnywhere, no hanging views and no unexpected disconnection in low-bandwidth situations—just a reliable HTTP session.
Fully scalable, whenever you're ready
If your long-term plan includes expanding to a full-fledged client-server fiber test and monitoring solution, invest in one or two Fiber Guardians, and migrate seamlessly to EXFO’s system solution (NQMSfiber) when you’re ready. Scaling up to NQMSfiber doesn’t require any change to the test units. NQMSfiber includes sophisticated functions, such as alarm management and reporting, trouble-ticket handling, and a view of the entire network status on a schematic. The system solution enables you to centralize your network operation and maintenance, and integrates with your existing network management systems. NQMSfiber can also be provided with network documentation based on GIS for mapping of the as-built and fault-on-map feature.
Proactive testing - Be a step ahead
From reactive to proactive
Define, run and analyze a series of OTDR acquisitions on multiple fibers, whenever you like, without having to do it all manually. Don’t just wait for trouble to occur — put a Fiber Guardian to work and gain control of the situation. Fiber Guardian is a multitasking test unit that allows for several different tests to be run concurrently and that also enables multiple users to access and view results during testing or upon completion.
Fiber Guardian captures and logs events based on thresholds. These thresholds can be specific to each test or to each port. Each fault event, newly created or cleared, activates OTDR result storage, permitting analysis of intermittent situations without storing an enormous quantity of unnecessary measurements.
Top-of-the-line measurements
Fiber Guardian was designed to serve various sections of your network. The following are a few examples of the test and measurement know-how and expertise engineered into Fiber Guardian:
- Highest measurement range on the market, allowing you to maximize your investment
- High-resolution scans (1 m): resolve closely spaced events such as connectors or mechanical splices at an access site
- Degradation measurement based on peak-level monitoring: can be used in conjunction with demarcation elements strategically located in the network
- Learning function: automatically establishes and optimizes fault-detection thresholds across full dynamic range
- Season-change management capability: extends learning to incorporate small changes to your reference data and to your fault detection thresholds—or reset to re-optimize around new average values
- Fast and simple operation: immediately detects degradations and locates them accurately with only one reference trace, whereas other solutions require two scans to perform this task.
Fiber Guardian can be set to monitor certain parameters more closely than others. For example, it can check a particular section and/or total loss degradation more closely, while being less sensitive to event loss degradation or reflective peaks. Keep an eye on what you really want to know.
Strategic operation
Fiber Guardian is also a multiport OTDR unit with the capability to record a situation at T0 and report it automatically, or on demand if the situation changes. Testing can be performed invarious modes, from simple manual unplanned tests to programmed testing that can be executed repeatedly on an hourly, daily or weekly basis at a set time.
- OTDR testing – Performs unplanned and fully manual tests with a result download.
- On-demand testing – If a fault condition exists, it is logged and alerting starts.
- 24/7 monitoring – Only fault-related events are stored.
- Scheduled testing – Tests can be set for predefined times and repeated (daily, weekly).
SMS features: test and alert tool
Keep a close eye on your fibers and cables. When a problem occurs, Fiber Guardian can alert you through SMS, regardless where you are. An SMS message is only sent to you when faults occur, or when they are cleared by a user or resolved by the remote test unit. If you want to check the status of a fiber through SMS, simply enter an easy-to-remember SMS code identifying the port and test setup, and then send it to Fiber Guardian, which will process the test immediately. If a fault is found, an SMS alert will be sent back with details.
Peace of mind — doing all the work for you
Open, secure and advanced
Based on today’s most advanced technologies, Fiber Guardian is reliable and secure. Installed on your LAN, it provides a test access point to your field technicians, central office operators or test experts.
Fiber Guardian has a local data storage capacity of up to 80 GB, protected with a RAID configuration. Fiber Guardian provides the status of your RAID and other subsystems. A dry-contact relay opens if one of the subsystems becomes faulty, even in the event of a power shutdown.
Based on an embedded operating system, the unit is a web server that allows local or remote access, just like any other web server on the network.
Easy to integrate with your systems
If you want to integrate Fiber Guardian with your own network management system, this can be done quickly and efficiently thanks to the availability of documented (.chm) web services. Simply create a mailbox and capture XML alerts that your system can query and manage like any other alert from your other network elements.
Self-learning, plug-and-play unit
Fiber Guardian can be put to work right at your desk. Any free test port can be connected to a designated cable termination port, following which the unit will search for a new fiber and start monitoring when you decide it is time.
If you have limited knowledge of what the fault-detection thresholds should be for this new fiber, simply select the appropriate sensitivity level for each section or event—fine, normal or coarse — and Fiber Guardian will take care of the rest. Other discovery functions include:
- Auto-naming of all test entities and setups
- Auto-detection of optical modules and hardware to facilitate upgrades or module swap
Advanced functions
- Packages can be updated through a connection to a secure FTP site, and you can schedule your update to run at a predefined date and time
- PASS/FAIL remote verification of optical ports
- Check optical connection quality from your desk
- Multiple optical test heads, with each one containing an OTDR for a higher level of surveillance of your critical fibers
- Multimode fiber version of test head (on request)
- Adjust to seasonal variations efficiently
- Extend the learning function, which can be programmed automatically
- Demarcation point monitoring
- Monitor peaks beyond RBS end-of-fiber
