Hardware Installation and Maintenance Guide
Context
Invisible laser beams will cause eye damage. Do not look into bores of optical modules or
connectors of optical fibers without eye protection.
l A router must use Huawei-certified optical modules. Non-Huawei-certified optical
modules cannot ensure transmission reliability and may affect service stability. Huawei is
not responsible for any problem caused by the use of non-Huawei-certified optical
modules and will not fix such problems.
l Do not over bend optical fibers. The bend radius of an optical fiber should be no less than
40 mm.
l Do not bundle optical fibers too tight. Otherwise, optical fiber performance may be
degraded, affecting communications between devices.
NOTE
The methods for connecting optical modules and optical fibers to different routers are the same. The
following uses an AR2220 router as an example to describe how to connect optical modules and optical
fibers.
Procedure
Step 1 Gently push an optical module into an optical interface until you hear a click.
NOTE
If the optical module cannot be completely inserted into the optical interface, do not force it into the
interface. Turn the optical module 180 degrees over and try again.
Step 2 Remove the dust plug from the optical module.
