4.4.3 Optical Fibers
On the ATN 905, optical fibers are used to input and output Ethernet service signals.
NOTE
In different application scenarios, indoor and outdoor ATN 905 devices use different optical fibers.
Specifically, indoor ATN 905 devices use indoor optical fibers and outdoor ATN 905 devices must use
outdoor optical fibers when installed outdoors.
Indoor Optical Fibers
Indoor optical fibers include single-mode optical fibers and multi-mode optical fibers. The
appearances of a single-mode optical fiber and a multi-mode optical fiber are the same, but their
colors are different. The single-mode optical fiber is yellow, and the multi-mode optical fiber is
orange.
shows the appearance of a single-mode optical fiber.

Appearance of a single-mode optical fiber with LC/PC connectors
LC/PC connectors are used at both ends of the optical fiber shown in
. For an optical
fiber that connects an optical port on the ATN 905 to an optical port of another type on the peer
device, an LC/PC connector is used at one end and a connector of another type is used at the
other end.
