GPON Repeater – Range Extender
AN-G-PON-R, developed and launched by AD-net Technology, is an optical power amplifier for GPON links. Amplification and reshaping of optical signals can be realized using O-E-O (Optical-Electrical-Optical) conversion, support By-pass option.
- Provides 4 standard SC/UPC flange to aggregate client signals.
- Support optical power amplification of GPON link and transparent service transmission.
- Support amplification of dual channels of GPON link.
- Increases the splitting ratio to 1:128.
- Support the power down Bypass option.
- Effectively extends the PON transmission distance to over 50KM.
- Supports a variety of networking modes such as parallel and cascade connections for multiple amplifiers.

Since OLT logical distance limit, the maximum 60KM. AN-G-PON-R standard OLT / ONU module.
AN-G-PON-R ONU-side received power =PONU–Pline–L = 3-21-2 = -20
AN-G-PON-R OLT Side Received power = POLT–Pline–L = 4-21-2 = -19
OLT Received power = PAN-G-PON-R-ONU–P1: 128–L = 3-22-2 = -21
ONU Received power = PAN-G-PON-R-OLT–P1: 128–L = 4-22-2 = -20
PONU——- ONU-side light emission power of 0-3dB, values 3dB
POLT——- OLT equipment, PON port luminescence 0-5dB, values 4dB
P1: 128——- 1 min splitter 128, loss ≤22dB
Pline ————60KM G.652 optical fiber, loss ≤21dB
L———- line interface and other losses, 2dB
Before conclusion, in theory, should be placed AN-G-PON-R splitter, the beam splitter to the OLT splitter line attenuation at the limit, so that there is sufficient light after spectral power, thus ensuring the long-distance transmission network PON.
Board Maintenance
Fault Location
Board service interruption occurs or unstable optical power failure, the steps may generally be positioned:
- Check and adjust the connection of the optical fiber. If the business returned to normal, the failure to resolve; if the fiber optic connection is normal, please proceed.
- Check and adjust the local board and the power terminal of the input light, to meet the requirements. If the business returned to normal, the failure to resolve; if the input optical power is normal, please proceed.
- Equipment failure, replace the device.
Troubleshooting
|
Symptom |
cause of issue |
|
ONU is not registered on |
Reason 1: OLT ONU equipment unbound Reason 2: The optical module input optical power exceeds the threshold range (normal is about -15dBm) Reason 3: dirty optical interfaces. Reason 4: equipment failure. Reason 5: Docking type of business interruption due to inconsistent service. |
|
Device error |
Reason 1: abnormal input optical power. Reason 2: Aging pigtail between the client and the client, bent, and resulting in a larger loss. Reason 3: The device temperature is too high. Reason 4: optical interface apparatus dirty. Reason 5: equipment failure. |
Here we’ve got 8 port OLT, PLC splitter, GPON ONT and GPON repeater in the middle of them to test it out.
