PON BasicsPON Basics

• Passive Optical Network

• OLT & ONTs are “active” and in buildings

• Fiber and splitters are passive

• Single PON usually supports 32 subscriber points

• Use less fiber than direct runs

Acterna Approach & SolutionsActerna Approach & Solutions

for PON testingfor PON testing

FTTx: T&M RequirementsFTTx: T&M Requirements

• Construction and Installation Testing

• Fiber characterization: => PON-OTDRtest of: fiber, splices, connectors and splitters at 1310/1490/1550nm

• Qualification of installed equipment: => OLTS, OBRoptical loss testing and optical return loss testing at 1310/1490/1550nm verification of fiber lengths

• PON Service Activation Testing and Troubleshooting

• Downstream power measurement => PON-PMwith selective 1490/1550nm power meter

• Upstream power measurement => PON-PMwith ‘through-mode’ selective power meter at 1310nm

• Service testing: IP testing

• Video testing

• Fault isolation and localization with OTDR => PON-OTDR

Downstream power measurement challenges

• Combined wavelengths on the fiber

• Two separate signals at different wavelengths / power levelse.g: 1490nm 622Mbps at -7 dBm

1550nm analog CATV at +13 dBm

• Standard PM not suitable

=> Wavelength selective PM with 2 detectors and high isolation filters (termination mode)

Loss Test Set

Testing Includes:

• Installation:Not required as potentially one splice along the link.So only one measurement from the OLT could bedone to qualify the splice close to the splitter

• Maintenance & Troubleshooting:OTDR will however be used for trouble shooting purpose

1. Test will be performed from the OLT if issue betweenthe OLT splitter (for simple analysis)

2. Test will be performed from the leg with launch cable if issueon the splitter or after it (for simple analysis)

3. When Digital video only will be available, in-service OTDRmeasurement could be possibly performed for troubleshooting
