Caution
:
When a fiber is not in use, ensure to cover the optical interface of the ONU
and the dust cap of the optical fiber. Prevent grease, dust pollution or water
immersion, which may lead to unavailable fiber and optical interface of the
device. If fibers need to be fixed or bended during cabling, do not fasten the
fibers too tight. Avoid fiber extrusion, which may lead to increase of fiber
material or unavailable fiber.
