3.0 Safety Information
Safety precautions should be observed during all phases of operation of this instrument. The
instrument has been designed to ensure safe operation however please observe all safety
markings and instructions. Do not operate the instrument in the presence of flammable gases
or fumes or any other combustible environment. VeEX Inc. assumes no liability for the
customer's failure to comply with safety precautions and requirements.
Optical Connectors
The test platform displays a laser warning icon when the laser source is active to alert the user
about a potentially dangerous situation. Make sure that optical sources are inactive before
connecting fiber to the test set to avoid skin or eye damage, or damage to the unit. It is
recommended to:
•Deactivate the laser before connecting or disconnecting optical cables or patchcords.
•Never look directly into an optical patchcord or an optical interface (e.g. CFP, CFP2,
CFP4, QSFP+, SFP+, SFP, OTDR, LS, VFL) while the laser is enabled. Even though
optical transceivers are typically fitted with Class 1 lasers, which are considered eye
safe, optical radiation for an extended period can cause irreparable damage to the eyes.
•Never use a fiber microscope to check the optical connectors when the laser source is
active.
Electrical Connectors
Telephone lines may carry dangerous voltages. Always connect the electrical test ports to
known test interfaces which carry low level signals.

OTDR Series e-Manual, RevE00 Page 11 of 128
4.0 Theory of Operation
4.1 OTDR
The principle of OTDR operation is based on measuring the Rayleigh back scattering signal
when a single powerful optical pulse passes through an optical fiber. The weak back scattering
signal is registered by an optical receiver, converted into digital form and averaged many
times.
The OTDR calculate distance with next formula:
Distance = c * t / (2 * n)
where c – light speed in vacuum, n – optical fiber index of refraction, t – time
delay between pulse emit and it
registration by receiver
Each sample converted by ADC into digital form is registered in the RAM. To measure the
back-scattering signal precisely, repeated triggering optical pulses is performed. The processor
averages samples, corresponding to the same points of the optical fiber that leads to the
increasing signal-noise ratio. After several cycles, the obtained signal values are transferred
from RAM and displayed. Then, the process of measuring, averaging, and cleaning RAM
registers is repeated again.
OTDR – Principle of Operation

OTDR Series e-Manual, RevE00 Page 12 of 128
4.2 Light Source
An optional light source is available and designed for generating continuous optical radiation.
The light source output is the same as the OTDR port and uses the same laser diodes and
optical splitter. The radiation power is stabilized with the help of external photodiode and power
stabilization circuit.
The light source has two operation modes: Continuous and Modulated/tone (270, 1000 and
2000Hz). One or all wavelengths (Loop) can be used in OLTS measurement.
The average power at modulation mode is 2 times lower (3dB) than in continuous mode of
operation.
4.3 Optical Power Meter
The OPM is equipped with an InGaAs photodiode (1mm diameter) to measure optical power.
The OPM will support both MM and SM fiber with the APC or UPC connector type. WaveID
can be enabled to detect source wavelength automatically when used with VeEX light sources
that also support WaveID. For more information on specifications, see the datasheet.
For extended measurement PM2 range (+25dBm), an integrating sphere with a photodiode is
used. Input power is attenuated by the integrating sphere by approximately 100 times.
The current of the photodiode is amplified and converted into digital form with the help of
analog-digital converter. The received digital signal is processed by microprocessor and the
value of the measured optical power is displayed.
4.4 Visual Fault Locator
The unit is equipped with an optional Visual Light Locator (VFL) to visually identify breaks in
the fiber typically hidden in the OTDR dead zone.
•Output power: 0 dBm (Typical)
•Operation modes: Continuous wave (CW) or 2Hz modulation

OTDR Series e-Manual, RevE00 Page 13 of 128
5.0 Basic Operation
5.1 Test Ports and Interfaces
OTDR testing: The optical fiber under test is connected to either the OTDR or OTDR-AUX
(Filtered SM or MM) port on the top panel. The type of the optical fiber connector must
correspond to the OTDR connector or adaptor type, including the connector polish.
Optical Power Meter (OPM) testing: The optical fiber is connected to the OPM port on the
top panel. Depending on fiber connector type, use interchangeable adaptors. FC, SC, ST or
LC type are supplied standard.
Visual Fault Locator (VFL) testing: The optical fiber is connected to the VFL port on the top
panel. The VFL interface is fitted with universal 2.5mm sleeve accepting all 2.5 mm connector
ferrules. A 2.5mm to 1.25mm converter is available.
Optical Connections
The optical fiber connector must be cleaned prior to connecting to the fiber under
test. Dust and dirt severely impact optical performance. For more information on
fiber handling procedures and tip cleaning, see Section 6.0 Test Fiber and Initial
Preparation Introduction.

used properly, the screen is designed to give years of reliable and precise operation.
Always use the stylus supplied with the unit to operate the touch screen. Never use
any sharp object such as a ballpoint pen, screwdriver, or similar item as this will
damage the screen and void the warranty. The touchscreen can be recalibrated
when needed. For more information, see the platform user manual at
