XPon Repeater, Gpon/Epon Amplifier
XPon REPEATER are used in GPON/EPON networks to extend distance up to 45km. These devices are used to amplify optical signals between OLT and ONU in ODN link, to extend transmission distance and increase optical ratio.
It adapt the OEO (Optical Electrical Optical) regeneration technology to recognize 3R (Regeneration, Reshaping, Re-timing), amplify GPON line optical ratio, extend transmission distance, and increase the splitter ratio. These devices are small and exquisite, are easy to install, and can be widely applied in GPON/EPON system markets such as, broadcast network, carrier network, electricity and traffic network, enterprise network and more.
Amplifying optical power of GPON/EPON lines and transmitting services transparently
(Regeneration, reshaping and retiming) 3R amplification with extracted clock signals.
Expanding coverage and prolonginging transmission distance to 80 km
Flexible networking by cascading multiple devices in serial or parallel mode.
Saving OLTs, prolonging networking distance, and increasing optical splitting ratio.
Easy installations, maintenance, plug and play.
Cut cost to enhance the investment returns..

Where, OLT--->OEO BOX trunk supports 40km transmission;
OEO BOX--->ONU supports 20km/1:64 ODN power budget. Refer to the below
figure for details:
Properties of EPON OEO’s physical layer
OEO Properties of ONU/OLT optical interface’s physical layer
–Receiving sensitivity of OLT optical interface <= -28dBm
–Optical power of ONU optical interface <= +1dBm
–Receiving sensitivity of ONU optical interface <= -28dBm
