ARGUS^® F300: the universal fiber tester
The ARGUS^® F300 is a pure fiber tester that combines OTDR and selective OPM and is also able to determine and display the PON ID and XGS-PON ID. It is the only device in the world that combines these fiber test functions in one device.

Modern design and intuitive operation
Its robust design combines the requirements for a compact hand-held meter in daily field use with the performance of a highend tester. The ARGUS^® tester with touch-screen display enables intuitive navigation of the familiar ARGUS^® menu structure. The operation is as easy as with a smartphone and an internal help function supports the rapid and reliable interpretation of test results.

Tests on mixed optical fiber accesses
The ARGUS^® F300 reliably tests on GPON and XGS-PON interfaces in the quality you have come to expect. The selective 4-fold power meter can be switched into an existing PON connection in through mode, allowing the optical levels on the different downstream (OLT) and upstream (ONT) wavelengths for GPON and XGS-PON and a video overlay to be determined precisely at the same time. In this process, other transmitters that may be on the line (so-called alien ONT) can be detected. In addition, the PON ID can be read out from the PLOAM message. A PLOAM monitor scans all ONU IDs and serial numbers of connected ONTs on a PON branch. With the 5xOPM, a video overlay via five separate filters is also possible as an option. On GPON as on XGS-PON, the ARGUS^® can also perform a complete ONT simulation with IP and performance tests at up to 10 Gbit/s.

Additional features
The ARGUS^® F300 also has many other test functions, such as WLAN analyzer, triple play tests such as VoIP, IPTV and data tests in the form of upload/download, ping and traceroute as well as iperf or high-performance IP speed tests directly on the fiber or on Ethernet. The OTDR measures the line and the event attenuation and, together with the propagation time of the reflected pulse, can determine the line length, splices and connectors. In addition, the Fiber Inspection Tool can be connected via USB, which detects scratches and defects on optical fibers and displays them as a video image and in tabular form.

FAQ
What does the ARGUS^® F300 measure?
The ARGUS^® F300 combines OTDR measurements, filtered power meter measurements, and broadband tests in a single device. It analyzes optical signals in GPON and XGS-PON networks, determines attenuation, reads out the PON ID, and enables a comprehensive evaluation of fiber-optic links and PON connections.

When is the F300 used?
The ARGUS^® F300 is used for installation, commissioning, maintenance, and troubleshooting in fiber-optic networks. It combines OTDR analysis with PON measurements, speed tests up to 10 Gbit/s, and WiFi7 tests, making it suitable for comprehensive testing of modern GPON and XGS-PON networks.

What is the difference between an OTDR and a power meter?
A power meter measures the optical power and attenuation of a fiber-optic signal. An OTDR, on the other hand, analyzes the fiber-optic line itself and detects events such as attenuation, reflections, splices, or breaks along the line. Both measurement methods complement each other during the installation and troubleshooting of fiber-optic networks.

What is an OTDR used for in fiber-optic networks?
An OTDR is used for analysis and troubleshooting in fiber-optic networks. It helps locate and evaluate splices, connectors, attenuation, or fiber breaks along a fiber-optic line. This enables the targeted identification of sources of error in GPON and XGS-PON networks.
