INFORMATION

Overview:

       PON technology has been applied more and more widely in the domains of private network communication such as electric power, coal mining, broadcast and television, and army. As we know, the transmission distance in a PON system is restricted within 20km scope. Owing to the restriction of OLT transmission distance, the quantity of ONU devices has to be reduced in order to lengthen the transmission distance, which results in great waste of OLT interfaces and optical fiber resources occupied by OLT. Furthermore, the optical power is often small but the transmission distance typically exceeds 20km in these applications, in particular, the optical fiber resources may very possibly become inadequate at the entrances of optical fiber to communities or key clients.

      BAUDCOM’s GPON OEO repeater amplifier is an optical transmission equipment which magnify and reshape signals during optical transmission process. The GPON repeater amplifier can provide 3R (i.e. re-amplification, reshaping and retiming) regeneration to signals during optical transmission, amplify weak input of optical signals, complete regeneration of electrical signals, and make transmission distance of PON become longer and support more extended users.The PON OEO fiber repeater/amplifier device 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.
