ST3300 1625 nm OTDR/handheld OTDR
I. Brief 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.
ST3300-1625 is a unique product mainly designed for construction and maintenance of telecommunication and CATV networks. ST3300-1625 can be widely used in engineering construction, maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, ST3300 is more compact in size and easier for field use.
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.

The Specification describes the guaranteed performance with the typical PC type connector when measuring; not consider the uncertainty because the refractive index of the fiber.
The dynamic range is SNR =1 the maximum pulse width within averaging time of 3 minutes
Conditions for dead zone measurement: reflection strength beleow-45dB, Event Dead Zone with 10ns pulses width measurement, Attention Dead Zone 50ns pulse width measurement.
Not include the uncertaint due to refraction of the fiber.
The products with different specifications, sampling rate will be different
