The XC-850 is a new concept in the evolution of Optical Time-Domain Reflectometers (OTDRs). It has been designed specifically with the requirements of the premise datacom installer in mind. In this environment many of the features associated with complex telecommunication OTDRs are not appropriate and many new features are desirable.
Datacom fiber links are short lengths of fiber installed as part of a Local Area Network (LAN) within a building. Many topologies are used but all require the individual fiber segments to be tested to measure the loss of the fiber and the connectors.
The XC-850 is the OTDR to measure fiber loss and connector loss of the datacom links. It does it automatically and it does it quickly. It stores the results for use later in a report and most importantly will establish the cause and precise location of any faults.
This cannot be achieved using other techniques such as a light source and power meter.
There are normally many individual fibers in a LAN installation especially where fiber to the desktop is used. The XC-850 has many features to aid the measurement and documentation of these installations: Automated link analysis, a full keyboard to annotate cable and fiber identities, a barcode reader option, an automatic duplex cable option and a large capacity storage card for all the results.
