Password Request
The splicer must be opened in order to activate or deactivate the password request.
Danger
The fusion splicer or electrically operated accessories must not be opened except by
suitably qualified personal. Switch off fusion splicer. Pull power supply plug and 12-V
lead.
Open the front
panel see section 7.
Activating the
password re-
quest
The PC board which is now visible (see figure) contains a switch for activation or deac-
tivation of the password. If the password request is deactivated, the stored password is
deleted when the equipment is switched on again. However, the old password is re-
tained if you reactivate the password request before the equipment is switched on and
off. On renewed activation of the request there is no password stored. It is therefore
necessary to define a new password first (Parameter “Password”, see below).
M=23%
Switch “off”:
request acti-
vated.
Entering the
password A password consists of an arbitrary sequence of five input keys. If you try to change a
parameter while the password request is activated, the message “Enter password” ap-
pears. If an incorrect password is entered, the change of parameter is rejected. This
applies also to a change of password, i.e. a new password cannot be defined unless the
current password is known. To redefine the password, activate the parameter menu,
select the parameter “Password” and proceed according to the following flow chart:
Change password? Enter password?
Only if password already exists
Enter new password
Confirm password Password wrong

Operating Instructions 1-3 M90 Fusion Splicer
Issue 02/97 Getting to Know the M90 Fusion Splicer
General
The microprocessor-controlled fusion splicer is employed to produce mechanically
strong, durable and low-loss connections between optical fibers.
Fiber diameter It is possible to connect single-mode fibers, dispersion-shifted single-mode fibers and
multimode fibers up to a maximum coating diameter of 900 µm. The splicer is designed
for the standard fiber outside diameter 125 µm (without coating). If you want to fuse
other fiber diameters, please contact the manufacturer.
Automatic fiber
positioning The fibers are positioned and fused automatically. This ensures consistently good re-
sults irrespective of the operator. Two mutually independent processes for positioning
and automatic splice loss calculation are incorporated into the splicer. The proven LID
system (LID = Local Injection and Detection) allows the user to perform exact core-to-
core positioning of the fiber ends so that usable splice results can also be obtained in
the case of single-mode fibers with eccentric cores. It also allows the user to measure
the splice loss at the operating wavelength of 1300 nm. If the LID system cannot be
used (e.g. in the case of tight buffered fibers), the finished splice is analyzed with the
L-PAS video system (Lens Profile Alignment System) and the splice loss likewise
given in dB.
Automatic
fusion time con-
trol
The LID programs with automatic fusion time control measure the light transmitted
through the fusion point during the fusion process. The optimum fusion time for each
individual splice is thus selected automatically.
Flexible
software The splicer is equipped with a flexible software package that allows the user to adapt it
to all conceivable applications:
The following programs are provided:
- LID programs with automatic fusion-time control for minimum splice loss
- L-PAS programs for special fiber types
- Special programs with preselectable fusion time and programmable fusion current
profile
- Attenuation splice program for making attenuators up to 10 dB
Splicer
shutdown The splicer shuts down automatically 30 minutes after the last operation in AC power
mode. In battery mode, the operator can select the shutdown time himself.
Accessories At the customer's request, the splicer can be equipped with various accessories such
as a battery, cleaver and splice tray holder. For accessories, see section 7.

Issue 02/97 Getting to Know the M90 Fusion Splicer
The mechanical and electronic systems are housed in a sturdy aluminum case.
The splicer can be powered by connecting it to mains voltages of 95 V to 260 V and
50 Hz to 60 Hz, the integral AC-line adapter selecting the correct voltage/frequency
range automatically.
If the splicer cannot be powered from the mains, it can be operated by a battery instead
(accessories). If the lead-acid battery is fully charged, operation can be sustained for 3-
4 hours if no additional load (e.g. working light or heatshrink oven) is connected. When
the battery is run down it can be recharged by means of the integral charger even if the
fusion splicer is switched off. The splicer can still be used while charging is in progress.
The splicer can also be operated from an external 12-V power supply.
Power Supply
Overview The terminal panel is located in the rear third of the splicer and features the sockets for
the power supply, charging indicator and mains switch ("I").

LID system The LID system allows exact core-to-core positioning. It consists of a transmitter and a
receiver. The optical fibers that are to be connected are inserted into the transmitter
and receiver. Located in the LID flaps there are the mandrels for bending the optical
fibers.
Principle Light can normally be launched into the core of a straight fiber only at its end face. If the
fiber is bent around a sufficiently small radius, however, such as occurs here at the
mandrels of the holder flaps, light can be launched into or extracted from the fiber
through the primary coating.

Launching/
extracting the
light
At the radius of the mandrel on the transmitter side, the light from an LED is radiated
into the optical fiber at a wavelength of 1300 nm. Part of this light is transferred into the
core of the second optical fiber at the splice point. The light emerges again at the re-
ceiver's mandrel and strikes a photodiode.
Optical power
as an electrical
signal
The extracted optical power is proportional to the transmission at the splice point. Fol-
lowing conversion to an electrical signal it can be used for automatic alignment of the
fiber ends and for automatic control of the splicing process itself.
Coating diameter Your splicer is equipped with a LID system for coating diameters of 250 µm.
The following options are available for fusing fibers of diameters 400, 500 and 900 µm:
- You can align and fuse the fibers fully automatically by selecting the "Fixed parame-
ters (video)" program group in the Parameter menu. This program aligns the ends of
the fibers using the video camera, the LID system not being required.
- Align the optical fiber manually.
- Use an external optical attenuation test set, the test set being connected to the
splicer's external LID input. In this case, you can perform fully automatic fusion by
selecting the "Fixed parameters (LID)" or "Variable fusion curve" program group in
the Parameter menu and switching there to an external LID system (see section 3).
Note
When using the internal LID system, use only optical fibers with the correct diameter
(250-µm coating)
Pigtail
adapters To fuse pigtails to fibers, pigtail adapters are available for various connector types, al-
lowing the LID system to be used (see section 8).

External LID
input The LID system cannot be employed for optical fibers of diameter > 250 µm over the
coating or for optical fibers with a color coating impermeable to light.
If you have an external attenuation test set, you can nevertheless still perform fully
automatic fusion by selecting the "Fixed parameters (LID)" or "Variable fusion curve"
program group in the Parameter menu.
The external attenuation test set must have the following features:
Permissible output voltage Uout 0 V ≤Uout ≤10V
Voltage level Variable DC voltage
Wavelength 800 - 1600 nm *
Settling time (rise or fall time of output
voltage) 10 ms - 500 ms *
Signal-to-noise ratio of output voltage >20 dB
Recommended output voltage range for
automatic mode 1 V ≤Uout ≤10 V
* can be set in Parameter menu
Jack plug A two-pin or three-pin plug of diameter 3.5 mm and a shielded cable must be used for
connecting the external analog attenuation test system.
+-
Connecting the Plug
The "-" and "Ground" connections are interconnected in the splicer.
If your external attenuation test set has a settling time of 10 ms, the splicer functions
automatically at the original speed. If the settling time is very long, e.g. 200 ms, the
positioning procedure can take significantly longer.
