Note

For the optical module with the transmission distance exceeding 40 km or above, add one online optical
attenuator on the link to avoid the overload of the optical receiver when short single-mode optical fibers
are used.

Optical modules generate laser. Do not look directly into the optical module.

To keep optical modules clean, use dust caps when the modules are not connected to
