Information

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.

ST3300-1625  can be widely used in engineering construction, maintenance test and emergency repair of all fiber optics related systems. 

ST3300-1625 has 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:

①The Specification describes the guaranteed performance with the typical PC type connector when measuring; not consider the uncertainty because the refractive index of the fiber.

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

③Conditions for dead zone measurement: reflection strength beleow-45dB, Event Dead Zone with 10ns pulses width measurement, Attention Dead Zone 50ns pulse width measurement.

④Not include the uncertaint due to refraction of the fiber.

⑤The products with different specifications, sampling rate will be different
