Description

AD-net AN-UM-EPON-R EPON OEO equipment is an optical transmission equipment which magnify and reshape signals during optical transmission process. It can effectively save OLT quantity and lengthen network transmission distance. The OEO fiber repeater equipement have been widely applied for long-distance transmission in various optical communication applications. Its advantages include in small size of optical signals, being economical and safe, and simple installation etc. Therefore, it can be applied in various optical transmission fields.
