Laser safety
The provisions contained in two standards define the safety procedures to be
observed both by users and by manufactures when utilizing laser products:
• EN 60825-1 : 1994 - Safety of laser products – Part 1: Classification of
products, requirements and user guidelines.
• FDA 21 CFR § 1040.10 - Performance standards for light-emitting products -
Laser products.
Due to the range of possible wavelengths, power values and injection
characteristics of a laser beam, the risks inherent in its usage differ. The laser
classes form groups representing different safety thresholds.

the instrument and follow the manufacturers instructions.
Important Measurements on optical fibers are difficult to execute and the preci-
sion of the results obtained depends largely on the precautions taken
by the user.
AC/DC and battery safety
Important In conformance with the recommendations of standard EN 61010,
the instrument should be operated within the manufacturer’s guide-
lines. Failure to do so may compromise the protection offered by the
instruments design.
Important Do not use any AC/DC adaptor or battery other than the supplied
accessories. If another adapter or battery is used, it may damage the
MTSeitself.

1Measurement Principles
This chapter give the principle of measurement :
❏for OTDR modules
❏for OTS modules
❏for the WDM modules
OTDR measurements principle
Optical time domain reflectometry consists of injecting a light pulse down the
optical fiber to be analyzed and observing, at the point of injection, the intensity
of the light reflected back in the opposite direction to the pulse propagation.
The detected backscattered (or retrodiffusion) signal is a decreasing exponential,
to which peaks caused by reflection from fiber connectors, splices or faults are
added.
Typical backscattered trace
Measurement result
The backscattered signal primarily allows the location of a segment of the fiber to
be found on the link.

Measurement Principles MTSe
The measurement result should provide:
•the attenuation
•the location of faults in terms of distance from defined point
•the attenuation versus distance (dB/km)
•the reflectance of an event or an optical link
Attention In so far as location is concerned, it should be noted that an OTDR is
a time domain machine (Optical Time Domain Reflectometer). Con-
sequently, group velocity must be introduced in order to determine
the distance of the location. This is done by introducing the refrac-
tive index of the fiber into the instrument.
Measurement validity
The ITU-T Recommendations G.651 and G.652 state backscatter measurement as
the second replacement method for the measurement of attenuation. The cut
fiber technique is the reference method.
The field of application for backscatter measurement is not limited, but the
conditions for application of this method are nevertheless stipulated:
•In so far as insertion conditions are concerned, Fresnel reflections should be
limited at fiber input.
•A high power source (laser) should be used.
•Receiver bandwidth should be selected so as to achieve a compromise
between pulse rise time and noise level.
•Backscatter power should be represented on a logarithmic scale.
Reflectance
Reflectance is a characteristic allowing the reflection coefficient of a reflecting
optical element to be quantified. It is defined as the ratio of the power reflected
by the element over the incident power.
The reflections are due to variations in refractive index along the fiber optic link,
in some Telecom applications. If these reflections are not controlled they may
degrade the system performance by perturbing the laser emitter operation
(particularly DFB lasers), or, in the case of multiple reflections, generate
interference noise in the receiver.
The OTDR is particularly suited to reflectance measurements on a fiber link. The
amplitude of the generated Fresnel reflection is measured, then the result is
converted to reflectance.
The conversion formula takes into account:
•the amplitude of the reflection measured
•the pulsewidth used to measure the reflection’s amplitude (in nanoseconds)

USER MANUAL 750000992/16 1-3
MTSeOTS Measurement principles
•the backscattering coefficient of the fiber used.
In order to measure the largest range of reflection coefficient, a variable optical
attenuator must be inserted between the OTDR and the link under test. This
attenuator allows the level of the curve to be adjusted so that the OTDR is never
saturated by the reflection to be measured.
OTS Measurement principles
Attenuation measurement
The attenuation measurement in power of a complete link or elements such as
fiber sections, connections, optical components, requires a calibrated laser light
source and a power meter.
This is generally deducted from the optical power measurement at two points:
Loss A(dB) = P1 (dBm) - P2 (dBm)
Important To make accurate measurements the following conditions are
required:
•Use a light source that is stable in time and in respect to the temperature.
•Verify that the connections, the fibers and the receiving cell are perfectly
clean.
•Use a reference link between the laser source and the element under test. To
make several measurements with the same light injection conditions, the
reference fiber must not be disconnected during the measurement period.
Two methods are used to measure the fiber optic attenuation:
•The cut fiber method
•Insertion loss measurement method
Cut fiber method
1. The power P1 at the output of the fiber under test is measured, then the fiber
is cut approximately two meters from the extremity at the source end.
Typical values of backscattering coefficient for a 1ns pulse
for a singlemode fiber - 79 dB at 1310 nm
- 81 dB at 1550 nm and 1625 nm
for a multimode fiber - 70 dB at 850 nm
- 75 dB at 1300 nm

Measurement Principles MTSe
2. The power P2 at the output of the fiber section of two meters is measured and
serves as the reference.
The attenuation of the fiber tested is: P1 - P2.
This method is very accurate but is little used due to its destructive nature. It
cannot be used during maintenance or installation but only during the
manufacture of the fiber.
Insertion loss measurement method
1. The power meter is first connected to the laser source via the reference fiber:
P1 is measured.
2. The fiber to test is inserted between the reference fiber and the power meter:
P2 is measured.
3. The difference between P2 and P1 gives the attenuation of the fiber under
test.
It is preferable to use the same type of connector at the extremities of the fiber
tested, in order to have the same connection conditions for the P1 and P2
measurements.
Although this method is less accurate than the previous method it is the most
common because it is non destructive.
Measurement accuracy
•Very high accuracy is often necessary, It is therefore essential to first make a
calibration without the fiber under test to eliminate as much as possible
losses due to the connections. To do this use the OTS “reference value”
function.
•For measurements in a laboratory where the two extremities of the fiber are at
the same site the repeatability of the attenuation measurements is better than
0.1 dB. For measurements in the field, with the extremities of the fiber at
different sites, the variations between measurements is in the order of ± 0.2
dB (using a relative measurement).
Power measurement
The measurement of the power transmitted or received only requires a power
meter:
•To measure the transmitted power, connect the power meter directly to the
output of the optical transmitter.
To measure the power at the input of an optical receiver, the power meter is
connected at the extremity of the fiber, where the optical receiver will be
connected.
WDM principle and analysis
The Wavelength Division Multiplex (WDM) technology is a very effective way to
increase the capacity of the fiber without having to install new links. Instead of
increasing the data rate, it enables the fiber to carry several wavelengths, each
wavelength transmitting signals. Channels are defined by the ITU-T
recommendations G-692.

USER MANUAL 750000992/16 1-5
MTSeWDM principle and analysis
With this new technology, new measurements are required. During installation
and maintenance of WDM systems, it is important to verify the following
parameters:
1. Presence of all channels at corresponding wavelengths, without any drift.
2. Right channel power levels, without any power variation
3. Enough signal over noise ratio (SNR). This value is determined by measuring
the ratio of the peak channel power to the noise power level of the ASE1noise
signals to the left and/or right of the carrier. Usually, the noise measurement
point is chosen as the calculated mid-point between two adjacent channels.
The measured noise power level is converted to a standardized bandwidth of
0.1 nm.
The most important test equipment for WDM systems able to perform those test
is the spectrum analyser. This analyser can be connected along the WDM system
on all critical measurement points, located at the extremities of the links or at the
amplifier locations.
Measurement results
The optical spectrum analyser displays a waveform which is showing all the
channels. Measured results are presented on a complete spectral analysis and as
a WDM table, listing all carriers with their relevant parameters.
The optical spectrum analyser is performing automatic detection and
measurement for all channels.
The number and the composite power are provided like, for each channel:
•the wavelength
•the spacing
•the power level
•the signal over noise ratio
The total power of the system could also be provided.
In order to qualify the amplifier, tilt and slope gain could be calculated. In
principle, the amplification shall be flat over the full WDM spectrum.

2Introduction
The Acterna 5000 series Media Test Set is a fully modular portable platform
designed for the construction, commissioning and maintenance of fiber optic
networks. This dedicated cost effective instrument allows testing to be fast and
easy.
It has the following principle characteristics:
❏It has a modular design that allows interchangeable modules to be adapted
for any present or future fiber optic application requirements. The MTSe
modular structure provides the flexibility and upgradeability for it to be the
tester of choice for extremely dynamic and rapidly growing
telecommunications, CATV and datacom markets. Easy field exchange
modules minimize the number of instruments to be carried.
❏It can contain in a small package, multiple OTDR functions, Fault Locator,
WDM analyzers, light source, power meter, VFL (Visual Fault Locator), OTS
(Optical Test Set), Talk Set, etc.
❏Its “RISC”microprocessor coupled with an optimized time base guarantees
excellent acquisition and processing speed.
❏Multitasking allows several operations to be performed at the same time, i.e.
acquisition, modification of parameters, file analysis, printing.
❏Software upgrades are easily achieved using the internal 3" 1/2 floppy disk
drive.
❏The measurement results can be stored in the internal 3 Mb SRAM memory
or, as an option, on a hard disk drive (1 Gb) or floppy disk drive.
❏The measurement tool, printing and file storage in the universal Bellcore GR-
196-CORE format, simplifies report creation.
❏The easy to use Man-Machine interface means becoming familiar with the
instrument is rapidly achieved. An external keyboard facilitates entry of data.
❏Its compact rugged box allows the instrument to withstand severe
environmental operating conditions.
❏The MTS 5100eis a mini-OTDR perfectly designed for field use.
❏The MTS 5200e, although in a very compact unit, is a classic mainframe
OTDR providing high level performance and functions, including a built-in
printer and IEEE interface.
Interchangeable modules
The MTSecan be equipped simultaneously with one or two of the following
modules:
•OTDR singlemode modules: SR, DR, HD, RTU
•OTDR multimode modules: MM, ML
•WDM modules

Introduction MTSe
•OTS modules: power meter, light sources and talk set.
Measurements
The MTSeallows long and short range tests to be made, in singlemode or
multimode, on point-to-point or complex optical networks during:
•the design and production of the equipment
•the installation and qualification of the equipment of the network
•the maintenance of the network
Les mesures peuvent être réalisées sur des liaisons optiques en service.
Measurements can be carried out on in service optical links with the 1625 nm
wavelength.
Simply pressing the START/STOP button starts or stops a measurement.
Setup
Pressing the SET-UP key provides access to the MTSeconfiguration menus:
Test setup
On the same screen, dialog boxes allow the selection of measurement
parameters, the results display and the parameters of the fiber.
System setup
On the same screen menus provide selection of:
•the screen parameters (automatic power off, backlight strength, contrast,
welcome message),
•the country parameters (date, time, date/time format, length units, language)
•the printing parameters: internal (MTS 5200eonly) or external printer or copy
to file, type of external printer, printing contents (trace or table or both)
•the I/O interface parameters : RS 232 or Ethernet (option) or IEEE (MTS 5200e
only), connector Centronics for keyboard or printer.
For a full description of the system set-up menus see "System setup" on page
3-12.
Instrument setup
A graphical screen displays all the modules available on the instrument and the
user can select the test functions. Only the Laser Source and Power Meter can be
simultaneous.
When the instrument is switched off, its configuration along with the
measurement results are saved.
The configuration menus can be displayed and modified during an acquisition
or a measurement. Some parameters are inhibited during acquisition.
Results
After any measurements, the trace and the associated results are displayed. The
RESULTS key calls back these trace and results after another display.
