As fiber optics plays more and more important role in modern telecommunication and CATV networks, the requirements to the construction test and maintenance of fiber optics links also become more prominent. OTDR CT-300 is a unique product mainly designed for construction and maintenance of telecommunication and CATV networks. CT-300 can be widely used in engineering construction maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, CT-300 is more compact in size and easier for field use. CT-300 handheld design, compact and lightweight, easy to carry. Event information through TFT color display and data storage capabilities. Through the USB interface, the test data can be uploaded to the PC, to facilitate the post-processing, archiving and printing.

Stable light Source Module Wavelength (± 20nm): The work of OTDR with wavelength
Notes: Specifications describe the instrument's warranted performance, measured with typical PC-type connectors. Uncertainties due to the refractive index of fiber are not considered; The dynamic range is SNR=1 the maximum pulse width within averaging time of 3 minutes; Conditions for dead zone measurement: Reflection strength below - 45 dB, Event Dead Zone with 10ns pulse width measurement, Attenuation Dead Zone 50ns pulse width measurement. Do not include due to refraction caused by the uncertainty. Stable source and OTDR sharing the same light port and OTDR work wavelength consistent.
