Note:

Fiber-optic connectors, according to ITU, are passive components that are used to stably but not
permanently connect two or more optical fibers. They are passive components indispensable to the
fiber-optic communications system in the sense that they allow optical channel connections removable.
There are many types of optical fiber connectors, such as:

FC: Round-shape threaded fiber-optic connector
ST: Round-shape plug-in fiber-optic connector
SC: Square fiber-optic connector
MT-RJ: Square transceiving fiber-optic connector

Note:

The two types of optical fibers are optional. You need to select fibers when purchasing an Router 1-Port
100FX MM FIC/100FX SM FIC; otherwise, they are not provided.

4.1.12 Connecting the Interface Optical Fiber

Caution:

When connecting an optical fiber, note that:

Do not over-bend the optical fiber. Its curvature radius must be no less than 10 cm (3.9

in).

Ensure that the Tx and Rx ends are connected correctly.

Ensure that the fiber ends are clean and free of dust.

Warning:

Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which are connected
with lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port.

Step 1: Locate the Rx and Tx ports on the interface card. Connect them to another
device with two optical fibers: Rx to Tx and Tx to Rx.
