2 Product description
2.1 Product function
FHO1000 optical time domain reflectometer (OTDR) is a new generation of
intelligent optical fiber communication measuring instrument. It is carefully
developed and produced by our company, and has undergone strict
mechanical, electronic and optical inspection and other standard quality
control processes before leaving the factory. It can measure the length of
optical fiber and optical cable, the distance between two points, and determine
the position of connection point, fault point and breakpoint of optical fiber and
optical cable.
The main features of the instrument are: integrated design, novel appearance,
strong and durable; small volume, light weight, easy to carry; easy to test the
loss, length and fault location of optical fiber link; with visual fault location
system, it is convenient to detect the fault location in the optical fiber line; the
battery in the machine has a long working time, which is suitable for long-term
field operation.
The instrument is widely used in engineering construction and maintenance to
detect fiber loss and fiber fault location. Main functions of the instrument are
as follows:
Measure the fiber length
Measure the distance between any two points on the optical fiber curve
Measure and display the loss between any two points on the curve (dB) and fiber
attenuation constant (dB / km)
Measure and display the connection loss of connection points on the curve (dB)
Measure the connector reflectance value
Auto fiber connection points searching function
Real time test function to test the fiber condition quickly
Test files can be saved automatically in the OTDR
Test files can be copy to the PC to make OTDR report
Support Chinese/English input
VFL(10mw)
OLS(>-8dBm)
OPM(-70dBm~+10dBm)
