GPON ONT STANDAR
4. Setup
4.1 Before installing your ONT device
Check for site’s environmental conditions and look for power and optical access points nearby.
Do not install the device in environments where the temperature or humidity exceeds the standard limits.
This device is a passive cooling device. There are thermal holes in the surface of the box. To prevent the overheating do not obstruct
these thermal holes.
The ONT device is not designed for outdoor setup. Pleae place it in a convenient indoor/cabinet environment.
Use only the provided power kit. The use of a 3rd party power adapter may not guarantee its proper operation.
To avoid any hazard or damage in your eyes, please never look directly into a fibre optic connector.
Never assume that the laser beam is inactive or that the optical fibre is switched off.
4.2 How to Setup your ONT
The ONT may be installed horizontally on a flat surface, wall mounted and ETSI rack (ONT 769503-MBH), quick steps for both of these setups are
described below.
Wall-mount
Remove the ONT lower cover;
Mount the cover on the wall using two screws inserted into the mountings shown in Figure 41(c). The lower mounting is used to regulate
the spatial orientation of the box. The space between the two screws should be about 4.8 cm;
Place the optical cable in one of the openings, (a) or (b) shown in Figure 4-12;
Pass the optical cable, in a clockwise direction, round the circular guide inside the ONT, wrapping it round as many times as necessary;
Fit the ONT into the cover as shown in Figure 4-12;
Attach the fiber to the optical connector inside the ONT;
Place a 3 mm plastic clip round the support and the optical cable before the point at which the cable exits the box Figure 4-12(d). Tighten
this just enough to ensure the optical fiber will not move;
Close the ONT
