VISTA B03 ONU can be used indoor or outdoor. Whether you install the ONU outdoor, in theservice 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.
To ensure that EPON equipment has the normally running and life-span, the environmentfor 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 mechanicfunction of the materials may be changed or the metallic components may rust. If the relativehumidity 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 causeinsulation materials to age much more quickly. The outdoor environmental requirements are asfollowing:
Table 1-1 Outdoor environmental requirements
Item Range
Temperature -40℃~+70℃
Relative humidity(when the temperature doesn’t change much)
95%+45℃
Relative humidity(when the temperature changes much: air/air)
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 onlyaffect 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.
ONU may be disturbed from outside. These disturbances will affect the equipment bycapacitance coupling, inductance coupling, electromagnetic radiation, common impedancecoupling (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 thedisturbance 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 cablemust be electromagnetic shielding cable.
� Interface cables must be routing indoor. Outdoor routing should as covert as possible. Thisis to avoid that the overvoltage and overcurrent of lighting will damage the signal interfaceof the equipment.
VISTA B03 series EPON equipment belongs to Type-1 laser equipment. If the light board ofthe VISTA B03 series EPON equipment is still running, please don’t see these light interfacesdirectly. The light bundles from the optical fibers contain high power, so they may harm theretina.
� Before cleaning the ONU, you must get out the ONU power plug. Don’t clean the ONU withwet 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 theONU.
� Don’t put the ONU on an unstable box or table. If it falls, the ONU will get damagedseriously.
� 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.
Right earthing of ONU is the guarantee for anti-lighting and anti-disturbance. So customers mustcheck whether ONU and the installation environment connect the ground cable correctly.Step 1: Check whether the ONU equipment and service box have been connected to the ground.Step 2: Check whether the service box and installation environment have been connected to the
Power input for VISTA B03 ONU is 220V AC or -48V DC.Step 1: Plug the power cable of ONU into the power socket in the service box.Step 2: Switch on the power of the service box.

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

the optical fiber into the optical interface.Step 3: Connect the other side of the optical fiber with the other side equipment.
When the equipment is installed in the service box, the service cables should be bundled upin the holder on the left side of the box. Cable routing is according to the environment. Allinterfaces of signal cables should be put at the bottom of the service box (They should be put insome place of the service where making them not possible to be touched). The power cableshould be routed from the right side of the service box. It is according to the environment thatchoice the short way to install.
� After bundling up, the cables must be lank and tidy in the cabinet. No twisting and bendingare 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 routingmay be adopted. When parallel routing, the distance between power cable and signal cableshould 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.
� 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 cabletie 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 besmooth 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 ofgreat 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 itwill not affect the running of the equipment, not damage the equipment or not damage thecable.
� 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 removablecomponent 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 behigh-temperature cable.
� If the cable connector is fixed by screw, the screw or nut should be firm and some measuresfor anti-loosening will be adopted.
� For some hard power cable, the cable should be fixed near the end point, to prevent thestress 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.
When checking whether the installation is correct, please make sure the power supply is off,to prevent the damage of human body and the equipment. After installation, please checkaccording to the items in the following table. The listed items must work normally.
