1.4. Power Requirements
The S178 Ver.2 fusion splicer can operate from any single-phase AC power source that supplies between
100-240 V at a frequency of 50-60 Hz with the S976A_AC adapter. It also has the S943B internal battery for
battery operation and the battery can be charged in the S958C unit by the AC power source through the S976A_
AC adapter or S977A_AC_adapter. It can also be charged while it is inserted in the splicer’s body.
!
WARNING
To avoid the risk of injury or death, ALWAYS observe the following
precautions before initializing the S178 Ver.2 fusion splicer.
Do not connect both AC and DC power sources at the same time
(Connect one source or the other).
If using a voltage-reducing auto-transformer to power the S178 Ver.2
fusion splicer, ensure that the common terminal connects to the
earthed pole of the power source.
Use only the type of power cord supplied with the S178 Ver.2 fusion
splicer.
Connect the power cord to a power outlet equipped with a protective
earth contact only (never connect to an extension cord that is not
equipped with this feature).
Willfully interrupting the protective earth connection is prohibited.
1.5. Toxic Hazards
The S178 Veer.2 fusion splicer presents no toxic hazards (under normal conditions of use, storage, and handling).
However, under the following conditions, certain precautions are necessary.
1.5.1. Incineration
Some of the electronic components included in the assembly are constructed with resins and other chemicals
that produce toxic fumes during incineration.
1.5.2. Acidic or caustic compounds
Some of the electronic components included in the assembly, particularly electrolytic capacitors, contain acidic or
caustic compounds. In the event that a damaged component comes in contact with the skin, wash the affected
area immediately with cold water. In the event of eye contamination, irrigate thoroughly with a recognized
eye-wash and seek medical assistance.
1.5.3. Physical damage
Some of the components used in the assembly may contain very small quantities of toxic materials. There is a
remote possibility that physically damaged electronic components may present a toxic hazard. As a general
precaution, avoid unnecessary contact with damaged electronic components, and arrange for disposal in
accordance with local regulations.

General Information
2-1
2. General Information
Fusion splicing is used to physically join together two optical fiber ends. The process may vary, depending on
the type of fusion splicer used. The S178 Ver.2 Single-Fiber Fusion Splicer has an active core aligning
mechanism to align the fiber ends, and a controllable electric arc to melt the glass and butt the ends together.
This results in a strong joint, with very low loss and very low back-reflection.
To achieve good splicing results, it is essential to know both the proper use of a fusion splicer and the
characteristics of optical fiber. Because all fibers are not identical, they can melt or fuse at different temperatures.
Therefore, to minimize splice loss, it is important that the arc power and the duration of the fusion arc be properly
adjusted. The S178 Ver.2 fusion splicer features an arc function inspection to help the user adjust these
parameters.
Other intrinsic factors that contribute to the increase in splice loss are core diameter mismatch, cladding diameter
mismatch, numerical aperture mismatch, core concentricity and non-circularity.
Core Diameter Mismatch
Cladding Diameter Mismatch
Numerical Aperture Mismatch
Different fibers have different numerical apertures. The aperture dictates the acceptance angle of light.

β
α≠β
Core Concentricity Core Non-circularity
Optical fiber is basically classified as either single-mode (SM) or multi-mode (MM). Single-mode fiber, which
includes dispersion-shifted fiber types, will transmit a single-mode (path) of data at wavelengths greater than the
cut-off wavelength (1170 nm). Approximately 80% of the light is transmitted within the core, and 20% is
transmitted in the surrounding cladding. Therefore, the transmission path is more accurately referred to as the
mode field and not as the core. With a core diameter of typically 8 µm and a mode field diameter of approximately
10 µm, single-mode fiber can transmit more data than multi-mode fiber and with less attenuation.
In multi-mode fiber, the optical signal is transmitted entirely within the core. These fibers have a core size of 50
µm to 100 µm (50 µm or 62.5 µm, typically) and are commonly used in local area networks (LANs), short distance
links and closed circuit television (CCTV).

Core Diameter/Axis offset
Because the optical signal is transmitted through the core of the fiber, it is important to understand how the cores
of the two fibers being spliced together compare. The following general formula can be used to show the effects
of core offset on the splice loss. The formula is only theoretical and does not take into account other extrinsic
factors such as cleave quality or dust contamination, and intrinsic factors such as core non-circularity and
numerical aperture.

A difference between A and B will cause a splice loss, even if d is zero. If using single-mode fiber, the
manufacturer of the fiber may be able to provide mode field diameter specifications.
It is impossible to have perfectly centered cores, because fiber manufacturing limitations often result in small
offsets. Today’s optical fibers are well manufactured and have core eccentricity of less than 0.5µm. However,
older fiber exhibits core eccentricity near 1.0µm.
The S178 Ver.2 fusion splicer, which has an active core alignment function by observing the core position with
microscope and image processor, aligns the cores of both fibers to minimize the axis offset described above.

3.1. Unpacking and Initial Inspection
1. Inspect the shipping container for any indication of excessive shock to the contents.
2. Remove the S178 Ver.2 carrying case from the shipping container, and open the case.
Ensure that the carrying case is right side up before opening.
3. Inspect the contents to ensure that the shipment is complete.
4. Lift the S178 ver.2 fusion splicer out of the carrying case, and place the instrument on a flat, smooth surface.
5. Visually inspect the S178 Ver.2 fusion splicer and all accompanying components for structural damage that
may have occurred during shipping.
Immediately inform Furukawa Electric and the carrier, if the contents of the shipment are incomplete, or if any of
the S178 Ver.2 fusion splicer components are damaged/defective, or if the S178 Ver.2 fusion splicer does not
pass the initial inspection.
Protection sheet is pasted on the surface of LCD cover, the surface of the switch panel,
and the surface of the label. Please peel off before using S178 Ver.2.
