1.31.31.31.3 EnvironmentalEnvironmentalEnvironmentalEnvironmental RequirementsRequirementsRequirementsRequirements

To ensure that EPON equipment has the normally running and life-span, theequipment room must keep the temperature and humidity. If the humidity in the room ishigh chronically, insulation materials will be not well-insulated or even creepage.Sometimes the mechanic function of the materials may be changed or the metalliccomponents may rust. If the relative humidity is low, fastening screw may get loosebecause the insulation piece will be dry shrinking. In the dry environment, it will take thestatic to jeopardize the circuit in the EPON equipment. The high temperature will causemore dangers. The long-term high temperature will cause insulation materials to age muchmore quickly. The environmental requirements of the equipment room are as table 1-1:

2.4.12.4.12.4.12.4.1 IntroductionIntroductionIntroductionIntroduction ofofofof splittersplittersplittersplitter

In the optical access network of the EPON system, ODN (Optical Distribution Network)exists between OLT equipment and the ONU equipment of the customer side. ODNconsists of trunk optical fiber, splitter and branch optical fiber.

Splitter is the indispensable component in the EPON system. As the passive devicewhich connects OLT and ONU, it transmits the input optical signal from the trunk opticalfiber to the branch optical fiber according to power ratio. The power ratio is usually 1:2, 1:4,1:8, 1:16, 1:32, all together five types. For the ratio 1:2, there are two types fortransmission, the power--even transmission and non-even transmission (can be set). Forother ratio, the power will be transmitted to the branch fiber evenly. For the upstreamtransmission, the optical signal of the branch optical fiber will be coupled to the trunkoptical fiber and then transmitted to the optical line terminal (OLT). No external power butincoming light bundle is needed for the splitter. And only power loss will be increased,because they will share the input (downstream) power. The loss is called loss of splitter orbranch ratio, always by dB. And it is determined by the number of output ports.

Splitter consists of one trunk optical interface and several branch optical interfaces.Carriers can choose different splitters according to different structure of the network.

When the splitter is installed in the OLT side, shelf-mounting splitter is suggested. It iseasy for installation.Step 1: Put the splitter on the chassis flat and keep it close the lateral columns of the shelf.Step 2: Fasten the screws to fix the splitter with the shelf.

Different splitters may be chosen according to the routing when the splitter is far fromOLT equipment or links up-layer splitter. Specific installation method is according to thesituation of actual project. After power-on, invisible light may be emitted from the opticalinterface, when the optical interface is not connected to optical connector or the protectivecap is opened. So don’t look at the optical interface directly. To keep the optical connectorclean, make sure to close the protective cap within 10 seconds. If optical connector is notinstalled in the optical interface, make sure to close the protective cap.Step 1: Take off the protective cap of the OLT optical interface.Step 2: Take off the protective cap of the trunk optical fiber connector of splitter. Then putit

� After bundling up, the cables must be lank and tidy in the cabinet. No twisting andbending are allowed.


Page 14 of 17 pages

Figure 2-6 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 thediameters.

� Different types of cables (power cable, signal cable, etc) should be routed andbundled up separately. Mixed bundling-up is not allowed. When they are near eachother, cross routing may be adopted. When parallel routing, the distance betweenpower 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.

� The metallic hole which the cable will get through should have smooth and roundingsurface, or have insulated bushing.

� Proper cable tie should be chosen when bundling up the cables. Two or more than twocable 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 shouldbe smooth without sharp corner.

Figure 2-7 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 frombreaking because of great stress.


Page 15 of 17 pages

Figure 2-8 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. Appropriateplace means it will not affect the running of the equipment, not damage theequipment or not damage the cable.

� The 220V AC power cable should not be bundled up in the track of removablecomponents.

� 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. Whenremovable component reaches the installation location, make sure the extra cable willnot 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 somemeasures for anti-loosening will be adopted.

� For some hard power cable, the cable should be fixed near the end point, to preventthe 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.
