2PON OEO GPON Repeater Amplifier

• The GPON repeater support four SFP slots(two OLT slots and two ONU slots);
• In accord with ITU-T G984.x & ITU-T G.988 and Chinese communication industrial standard (YD/T 1475-2006);
• Extend GPON system transmission distance more than 50km;
• Uplink: supports combination of different types of PON OLT interfaces and different physical connectors;
• Downlink: supports different types of PON ONU　interfaces (shunt or ONU interface).
• Be compatible with GPON system;
• Be compatible with GPON OLT and ONU equipment manufactured by different vendors;
• 1U desktop equipment, small space occupation and low power consumption;
• Supporting GPON OEO relay function
• Supporting 1550nm and 1620nm dual wavelength storage with externally connected passive equipment

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

–Optical power of OLT optical interface                      ≧   +0.5dBm

–Burst-mode signal time                                       ≦   50ns

–Fast AGC attenuation                                         ≧   10dB

Applying SFP optical interface module, connected as shown in the above figure.

In GPON system, it will not generate any error code to the system and have no adverse effects on transmission or performance.
