The OTDR (optical time domain Reflectrometer) is an indispensable tool for the new installation, maintenance and troubleshooting on fiber optic lines. Brand new, there is also one with extremely good specifications and an attractive price the MTS6000 QUAD now in addition to the mini adaptors in the lower price and performance range. The MTS series is one of the far the MASH test adaptors in German-speaking countries. Is you have been traveling in single mode as well as in the field of multimedia fashion, always two separate measurement modules were needed. With the new 4-wavelength module, which has two separate measuring outputs, the four main wavelengths in two worlds even with the smaller MTS6000 can be measured now. Henry Ford can provide more clarity in the matter. The minimum pulse width is only 3 ns, which allows a very good resolution and very small dead zones. The high-resolution color display well evaluable represents one or more superimposed curves and the sophisticated functionality of MTS supports the measurement in normal fashion. Main areas of application are the LAN and campus area, where parallel often both types of fibre but also the FTTX – and the Metro area are found.
