PON OEO Repeater GPON Amplifier

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.

Typical Application

1. Extend Transmission Distance

Note:  EPON system shall support measurement of corresponding physical  distance, and PON OEO device can only lengthen the distance on the basis  of optical properties.

2. Extension of splitting ratio

Note:  EPON system shall support online of corresponding 256 ONU, and PON OEO  can only extend the splitting ratio on the basis of optical properties

3. Parallel application

Note: EPON system shall support measurement of corresponding physical distance and differential range, and PON OEO device can only lengthen the distance on the basis of optical properties.
