The MU909015C/C6-057 from Anritsu Corporation is a Tri-Wavelength Optical Time Domain Reflectometer (OTDR) module that operate at wavelengths of 1310 nm/1550 nm or 1625 nm. It has a wavelength accuracy of ± 20 nm & ± 15 nm and pulse width of 5 ns - 500 ns & 1 μs - 20 μs. This OTDR has a dynamic range of 38 dB/37 dB/35 dB (at 20 μs) and 27 dB/26 dB/25 dB (at 500 ns). It has a dead zone of up to 0.8 m (Fresnel), 4 m (backscatter, at 1310 nm), and 4.5 m (at 1490 nm/1550 nm/ 1625 nm/ 1650 nm). This OTDR has a distance range of 0.5 km - 250 km and sampling resolution of 2 cm.

The MU909015C/C6-057 has a 4.3-inch Thin-Film Transistor (TFT) color LCD display that has a resolution of 480 x 272 pixels. This OTDR has a return loss measurement of 14.8 ± 2 dB and linearity of ±0.05 dB or ± 0.1 dB. It uses a single-mode 10 μm/125 μm fiber and has a sampling point of less than 250,001. This OTDR can be controlled via USB 1.1, Type A×1 (memory), and Type B×1 (USB mass storage) interfaces. It requires an AC supply voltage of 100 V - 240 V and a DC supply voltage of 9 V. This OTDR is available in a standard package that measures 190 mm x 96 mm x 48 mm and includes NiMH & alkaline dry battery.
