By revolutionising the concepts of optical time domain reflectometry (OTDR), the new XC850 crosschecking reflectometer from Megger brings all of the benefits of OTDR to fibre-optic data networks, with none of the conventional OTDR complexity and cost. The XC850 has been designed from the ground up to meet the needs and budget of the data network installer. Both the design and features have been optimised for superior performance in premises and campus networks.

The XC850 quickly determines the loss of a fibre segment, including the fibre, connectors, and length of the segment.

It stores results for use in reports and, more important, establishes the cause and precise location of any fibre impairments, providing a distinct advantage over an optical power meter and light source, without the complexity and cost of an OTDR.

Operator preferences are easily configured using menu screens on the instrument, or they can be set up using a PC, and be simply downloaded to the XC850 via the plug-in memory card.

Not only does this eliminate time spent on setting up the instrument on-site, it also means that operators can carry out tests accurately and effectively without requiring extensive training or experience.

Megger's XC850 crosschecking reflectometer operates at 850nm, and can be used on fibre systems up to 2km in length, with losses of up to 13dB.

The distance resolution is 0.5m, and an event dead zone (-40dB reflection) of less than 1m, the crosschecking reflectometer is the clear choice over an OTDR when testing optical data networks.

The unit is available in two versions: the XC850ST is fitted with a brilliant backlit colour display which is ideal for indoor applications, whereas the XC850SSR features a transflective colour display which can be easily read indoors and in bright outdoor daylight.

Both versions include a full alphanumeric keyboard which greatly simplifies the entry of the identification data relating to individual tests.

Data entry via an external barcode scanner is also supported.

Configuration data, test identification data and measurement traces are stored on removable memory cards in Telcordia GR196 format, as well as in standard CSV format, ensuring compatibility with virtually all OTDR software packages and with Microsoft Office applications.
