Passive Optical LAN Testing

Fronthaul to Backhaul Field Testings

Following the FTTH trend to deliver more bandwidth to the consumers, a new technology is rising to provide more bandwidth, more services and future-proof networks to the enterprises: passive optical LAN (POL).

Also called OLAN or fiber-to-the-desktop, this GPON-based technology creates a very cost-effective local area network (LAN) with virtually unlimited capabilities.

Singlemode fibers all the way to the desktop and optical splitters replace the traditional CAT5/6 cables and active Ethernet switches providing considerable benefits to the network owners:

  • CAPEX saving for cables and equipment
  • OPEX saving from lower energy and cooling (Green technology)
  • Space saving with fewer racks of equipment and no remote hubs
  • Secure and reliable communications over fiber-optic cables

Rely on EXFO's FTTH expertise to test your POL networks

When GPON networks were first deployed in FTTH, EXFO was there to test them. Since then, we have continued to focus on providing innovative and industry leading test solutions that will help you to efficiently address the challenges of deploying your private LAN networks. Take advantage of EXFO’s FTTH/POL technology leadership and expertise to deliver high-performance networks—the easiest way.

Key Testing Considerations What You Should Do What Tool Do You Need
Connector Endface Cleanliness Perform visual inspection to detect dirty/damaged connectors; clean them if required Fiber inspection probe
Fiber-Link Characterization Look for anything potentially impacting total budget loss (dB), such as macrobends, splices,
bad connectors, fiber breaks, etc.
OTDR-based fiber tester
PON Signals Validation During service action, check for power level assessment of active components to validate signal levels for all services. Pass-through PON power meter
Network Documentation Properly identify all fibers, test results and test reports. Post-processing software

Pulse Selection vs. Dead Zone

Application Notes

Generally speaking, the rationale behind selecting the shortest pulse on an OTDR is to obtain the best spatial resolution, and the best event and attenuation dead zones needed to detect and measure very closely spaced events.
