1.2
Unpacking Inspection
The product is transported in compliance with the standard assembly and shipping
procedures. On receiving the OTDR, please check the product list carefully against the
packing list, and the appearance and quality of the product to find out possible physical
damages that may be caused during transportation. If the package is found damaged, please
keep the original packing materials properly and meanwhile notify the freight carrier and
the agent that supplies the product to properly resolve the problem. The product package
should contain an OTDR, an SD card, a power adapter, and an installation disk of the PC
analysis software. If any item is missing in the package, please contact the agent that
supplies the product to properly resolve the problem.

Product Introduction
The OTDR launched by us is a reliable instrument used to characterize an optical fiber.
It features the compact size and simple operations, and adopts the ergonomic industrial
design and touch LCD screen. The OTDR supports the data storage function. The data can
be analyzed by using the PC software to obtain the transmission quality of an optical fiber.
In addition, the measurement results can be post-processed, archived, and printed. With
the data and images measured by the OTDR, you can evaluate characteristics of the entire
optical link. In particular, the loss feature and event distribution of the fiber under
test are visually displayed. You can use the OTDR to periodically check whether a link
meets the specification requirements. To record the transmission quality of an optical
fiber, you need to measure the optical path, total loss, and losses of all connectors.
By checking event points of optical fibers, engineers who install and maintain optical
fibers can point out faults of optical fibers, locate event points, and measure the
attenuation between event points, incurred losses, and uniformity of attenuation. In a
word, the OTDR is an indispensable tool for manufacturing, installing, or maintaining
optical fibers or cables.
The OTDR has the following characteristics:
Basic functions:
a) Measure the length of an optical fiber or cable.
b) Measure the distance between two points on an optical fiber or cable.
c) Determine the location of faults or breaks on an optical fiber or cable.
d) Describe the loss distribution trace of an optical fiber or cable.
e) Measure the attenuation coefficient of an optical fiber or cable.
f) Measure the loss between two points on an optical fiber or cable.
