Description

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. AN-G-PON-R can effectively amplify the optical power of a PON link and extend the network transmission distance. Due to its compact size and easy installation feature, the product can be easily deployed in the field with various access nodes to residential communities using fiber to the home.

Board Maintenance

Fault Location  
Board service interruption occurs or unstable optical power failure, the steps may generally be positioned:
  1. 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.
  2. 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.
  3. 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.

Applications

 
Since OLT logical distance limit, the maximum 60KM. AN-G-PON-R standard OLT / ONU module.
 
AN-G-PON-R ONU-side received power =PONUPlineL = 3-21-2 = -20
AN-G-PON-R OLT Side Received power = POLTPlineL = 4-21-2 = -19
OLT Received power = PAN-G-PON-R-ONUP1: 128L = 3-22-2 = -21
ONU Received power = PAN-G-PON-R-OLTP1: 128L = 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.
