Testing a Balanced PON Splitter with CertiFiber Pro

The CertiFiber® Pro Optical Loss Test Set (OLTS) can be used to check that the loss of a PON Splitter (often referred to in various standards as a non-wavelength-selective or wavelength-selective branching device) to check that it is within the allowed defined limits.  The CertiFiber® Pro has an operational mode called “Loopback” that can be employed to test optical splitters, no matter whether they are designed for outdoor, FTTX deployment, or indoor, Passive Optical LAN (POL) use.

This article describes the correct method for testing a balanced PON splitter for port loss using the CertiFiber® Pro, there will be a further article to address unbalanced PON splitters.  This method refers to the requirements of ANSI/TIA and ISO/IEC standards with reference to recommended splitter losses and connector losses.  As with all fiber testing, inspection is a critical component to successful measurements.  Without inspection, you may end up damaging the installed connectors.  The CertiFiber Pro® has a USB camera option for the inspection of end face connectors.  Users are encouraged to take advantage of this.
