1.2 Check Installation Environment
VISTA B03 ONU can be used indoor or outdoor. Whether you install the ONU outdoor, in the
service box or on the working platform, the requirements must be as following:
� Make sure there is enough space for ventilating of the ONU equipment, in order to facilitate
the heat dissipation.
� Make sure the service box or the working platform have the heat dissipation system
themselves.
� Make sure the service box or the working platform is firm enough to hold the terminal and
its accessories.
� Make sure the service box or the working platform is earthed.
1.3 Environmental Requirements
To ensure that EPON equipment has the normally running and life-span, the environment
for ONU must keep the temperature and humidity. If the humidity for ONU is high chronically,
insulation materials will be not well-insulated or even creepage. Sometimes the mechanic
function of the materials may be changed or the metallic components may rust. If the relative
humidity is low, fastening screw may get loose because the insulation piece will be dry shrinking.
In the dry environment, it will take the static to jeopardize the circuit in the EPON equipment.
The high temperature will cause more dangers. The long-term high temperature will cause
insulation materials to age much more quickly. The outdoor environmental requirements are as
following:
Table 1-1 Outdoor environmental requirements
Item Range
Temperature -40℃～+70℃
Relative humidity 95%

1.3.1 Cleanness Requirements
Dust is a danger for safe-running of the EPON equipment. When dust falls on the equipment,
it will take the static, which will lead to the poor contact of metallic connector or metallic junction.
Especially when the humidity is relatively low, the static is easier to be taken. It will not only
affect the life-span of the equipment, but also will cause the malfunction of the communication.
Besides the dust, requirements for the salt, acid, sulfide in the equipment room are demanding.
These Noxious gases will fasten the erosion of the metal and the aging of some components.
ONU should be put in clean environment.
1.3.2 Requirements for anti-disturbance
ONU may be disturbed from outside. These disturbances will affect the equipment by
capacitance coupling, inductance coupling, electromagnetic radiation, common impedance
coupling (including grounding system) and transmission modes of the cables (etc. power cable,
signal cable). So the following must be paid attention to:
� AC power system is the TN system. AC power socket must be the single-phase three-cable
power socket with protection earthing（PE）, to make sure the filtering circuit will filter the
disturbance of the electric network very well.
� Work location of ONU equipment should be far from super power radio-transmitting station,
radar-transmitting station and high-frequency high-current equipment.
� Electromagnetic shielding should be adopted if necessary. For example, interface cable
must be electromagnetic shielding cable.
� Interface cables must be routing indoor. Outdoor routing should as covert as possible. This
is to avoid that the overvoltage and overcurrent of lighting will damage the signal interface
of the equipment.
1.3.3 Safety for using laser
VISTA B03 series EPON equipment belongs to Type-1 laser equipment. If the light board of
the VISTA B03 series EPON equipment is still running, please don’t see these light interfaces
directly. The light bundles from the optical fibers contain high power, so they may harm the
retina.

1.5 Safety attentions
� Before cleaning the ONU, you must get out the ONU power plug. Don’t clean the ONU with
wet cloth. Don’t clean the ONU with liquid.
� Don’t put the ONU near water or in wet place to prevent water or humid gas to get into the
ONU.
� Don’t put the ONU on an unstable box or table. If it falls, the ONU will get damaged
seriously.
� Make sure the ventilation condition for the ONU and the equipment room is fine.
� The ONU can work only with the right voltage. So make sure the running voltage is the
same as the voltage signed on the ONU.
� To reduce the danger of electricity strike, don’t open the shell when the ONU is running.
Even when the equipment is power-off, don’t open the shell arbitrarily.

2.3.2 Optical fiber installation
Optical fiber connector introduction
When you choose the optical fiber, make sure the type of the chosen optical fiber connector
is the same as the type of the optical interface. Optical fiber connector is the indispensable
passive device in optical fiber communication system. Its usage will make possible dismountable
connection in optical channels. This will facilitate the debugging and maintenance of the optical
system, and make the linking more flexible. There are many types of the optical fiber connector.
We only introduce SC type and LC type.

2.4 Routing recommendation in the installation
2.4.1 VISTA B03 ONU installed on the working platform
When the VISTA B03 ONU is installed on the working platform solely, all service cables of
Page 10 of 14 pages
11. VISTA B03 EPON ONU Installation Manual
interface will be routed in the front of the equipment. The power cable of the equipment will be
routed from the back.
2.4.2 VISTA B03 ONU installed in service box
When the equipment is installed in the service box, the service cables should be bundled up
in the holder on the left side of the box. Cable routing is according to the environment. All
interfaces of signal cables should be put at the bottom of the service box (They should be put in
some place of the service where making them not possible to be touched). The power cable
should be routed from the right side of the service box. It is according to the environment that
choice the short way to install.
2.5 Cable bundling during installation
2.5.1 Correct usage of the sign
Before bundling up the cables，please write the sign correctly and then attach it at the
appropriate place.
2.5.2 Attentions during cable bundling
� After bundling up, the cables must be lank and tidy in the cabinet. No twisting and bending
are allowed.
Figure 2-4 Cable bundling (1)
� The bending radius of the cable should be no less than 2 times of cable diameters. At the
interface connector, the bending radius shall be no less than 5 times of the diameters.
� Different types of cables (power cable, signal cable, etc) should be routed and bundled up
separately. Mixed bundling-up is not allowed. When they are near each other, cross routing
may be adopted. When parallel routing, the distance between power cable and signal cable
should be no less than 30 mm.
� The cabling rack inside and outside the cabinet and the cabling slot should be smooth,
without sharp edges and corners.
Page 11 of 14 pages
12. VISTA B03 EPON ONU Installation Manual
� The metallic hole which the cable will get through should have smooth and rounding surface,
or have insulated bushing.
� Proper cable tie should be chosen when bundling up the cables. Two or more than two cable
tie together for bundling up the cables are not allowed.
� After bundling up the cables with cable tie, extra should be cut off. The incision should be
smooth without sharp corner.
Figure 2-5 Cable bundling (2)
� If the cables will get bending, then bundle the cables before they get bending. The cable tie
will not appear in the bending point, in order to prevent the cable from breaking because of
great stress.
Figure 2-6 Cable bundling (3)
� The cables, which do not need to assemble, or the extra part of the cables should be folded
and bundled up in appropriate place in the cabinet or the slots. Appropriate place means it
will not affect the running of the equipment, not damage the equipment or not damage the
cable.
� The 220V AC power cable should not be bundled up in the track of removable components.
� For the power cable of the removable components such as grounding cable of door, some
extra will be reserved after installing, to prevent the cable from stress. When removable
component reaches the installation location, make sure the extra cable will not contact heat,
sharp corner, edges and so on. When avoiding heat is not possible, the cable must be
high-temperature cable.
� If the cable connector is fixed by screw, the screw or nut should be firm and some measures
for anti-loosening will be adopted.
Page 12 of 14 pages
13. VISTA B03 EPON ONU Installation Manual
� For some hard power cable, the cable should be fixed near the end point, to prevent the
stress near the end point.
� Please don’t use screw which made by yourself to fix the end point.
� Power cable with the same type and the same routing direction should be bundled up
together. Then cables in the cable bundle should be clean and lank.
� No knotting are allowed when bundling up the cables or routing.
� For the cold-pressing end point (such as air switch), the metallic part of the old-pressing
end point should not be exposed outside when assembling.
