The new MW9076 mini-OTDR series can perform a measurement three to five times
faster than the well received, conventional MW9070B. Three and four-wavelength
OTDRs are included among the new product lineup. The four-wavelength OTDR can
measure the chromatic dispersion characteristics from one end of an optical
fiber. Two types of color displays with high resolution (5cm) and many sampling
points (50000 points) are available for indoor and outdoor use. The MW9076
series shows superior basic performance that enables a wide dynamic range and a
short dead zone. It supports the construction and maintenance of the optical
fiber cables. Moreover, using this OTDR, it is possible not only to quickly
charge a lithium-ion battery but also to indicate the remaining battery
charge.
