Caution
For the fiber module with transmission distance exceeding 40 km and more, one on-line
optical attenuator should be added on the link to avoid the overload of the optical receiver
when short single-mode optical fibers are used.
Fiber modules generate laser. Do not stare at light source.
To keep fiber modules clean, please use dust caps when the modules are not connected
with fibers.
