4.9 Connecting the EPON Optical Fiber to the ONT
The following procedure should be performed by the service provider or the cable installation contractor.
The EPON Multi-service Gateway ONT has a single SC/APC connector for connecting optical fiber to the
unit. Prior to installation, the service provider or cable installation contractor must have routed and secured
the optical fiber run from the utility pole or conduit, pulled and routed the individual fiber optic cable inside
the premises, installed any wall plate outlets for fiber distribution, and supplied any fiber optic jumper/patch
cable to connect to the EPON Multi-service Gateway ONT. The fiber optic cable (or patch cable) that con-
nects to the Multi-service Gateway must be terminated with an SC/APC connector for a proper connection.
If you obtained the fiber tray, you can wrap the optical fiber cable inside the tray and install the tray on a wall,
in preparation for snapping an EPON Multi-service Gateway onto it. A fiber tray example showing a view of
the optical fiber wrapped in the tray and the ONT poised to be snapped onto the tray is shown in Figure 12.

A typical wall plate example is shown in Figure 13.

The fiber optic cable should never be bent so that it exceeds its minimum bend radius during installation or
use. Exceeding the bend radius can damage the fiber inside the cable, or reduce performance due to distor-
tion of light along the fiber path. The fiber’s minimum bend radius is 1 ¼ inch (3.175 cm) as shown in Figure
14.
