In optical time-domain reflectometry (OTDR), the propagation length and reflection properties of light in the optical fiber are tested. A laser pulse is coupled into the fiber and the scattered light measured for a specific duration of time. This allows the losses generated through splicing, optical fiber attenuation, or reflection to be calculated.
Retroreflector modules for the installation and maintenance of FTTx networks.
Here you will find the OTDR plug-ins from Viavi for the MTS-2000 and MTS-4000 base units for FTTx network applications. These modules offer automatic and bidirectional OTDR measurements.
Two versions are available:
To test optical fiber transmission in FTTx/PON networks, the 4100 series OTDR module is used. This unit is used in automatic fiber inspection and IEC pass/fail analysis.
This measuring module is ideally suited for the installation, setup, and maintenance of FTTx/PON access, metro, and enterprise networks – at given wavelengths, this module locates errors reliably in PON networks.
The 4100 series OTDR modules contain an integrated power meter and an optical source in just one module.
These modules have the following features:
The OFS-100 FiberTrace and OFS-200 FiberCable reporting software is available for comprehensive postproduction of test results on a PC.
The FiberComplete modules function almost on their own: After connection, up to ten measurements are performed automatically at the push of a single button. This single unit contains as many measurement instruments.
The following measurements are possible: automatic, bidirectional measurement of insertion loss (IL); bidirectional optical return loss (ORL) using an OCWR method; and bidirectional OTDR or fault-finder testing.
Two FiberCompleteTM modules are required for complete bidirectional measurements. Communication between the measurement devices is implemented simultaneously via the fiber being tested. Highlights include the real-time continuity test, pass/fail analysis, and the direct generation of reports without having to connect to a PC. The modules can be used with the MTS-2000 and MTS-4000 base units.
The FiberCompleteTM modules have the following features:
The FiberTrace (OFS-100) and FiberCable (OFS-200) PC software is available for extensive postprocessing of the test results.
The MTS-4000 can also be equipped with triple-play service software on an optional basis. This software allows comprehensive IP testing to be conducted. This includes the following:
