INTRODUCTION


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.

Fibretool HW-358T is a unique product mainly designed for construction and maintenance of telecommunication and CATV networks. Fibretool HW-358T can be widely used in engineering construction maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, Fibretool HW-358T is more compact in size and easier for field use.

Fibretool HW-358T 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.

Notes:

①、Specifications describe the instrument's warranted performance, measured with typical PC-type connectors. Uncertainties due to the refractive index of fiber are not considered;

②、The dynamic range is SNR=1 the maximum pulse width within averaging time of 3 minutes;

③、Conditions for dead zone measurement: Event Dead Zone with 10ns pulse width measurement, reflection strength below - 45 dB; Attenuation Dead Zone 20ns pulse width measurement, reflection strength below - 55 dB.

④、Do not include due to refraction caused by the uncertainty.

⑤、different spec,maybe different sampling rate
