Overview
The MORL-A11308-STD-M112-MFA is a multimode insertion loss (IL) and return loss (RL) meter module from the VIAVI mORL-A1 family. It operates at 850 nm and 1300 nm, has a dual output for 50 µm (OM3) and 62.5 µm (OM1) fiber with software selection between the two, and uses FC/APC connectors. This is the standard (non-bidirectional) version of the dual-fiber multimode module.
The module is part of the VIAVI Passive Component/Connector Test solution (PCT), a family of modules, software and peripherals for testing insertion loss, return loss, physical length and polarity of optical connectivity products such as connectors, cable assemblies, structured cabling and splitters. It installs in a MAP-Series chassis and can be configured for R&D, production or qualification test environments.
Measurement principle
The multimode module uses the same basic technology and architecture as the single-mode mORL-A1. It has an integrated power meter, and IL is measured with the power meter method. RL is measured with time-domain technology, which avoids mandrel terminations. RL can be measured from 15 to 60 dB, concurrently with IL measurements, in less than 2 s per wavelength. IL performance meets the IEC 61280-4-1 recommendations for mode fill. Besides the laser sources used for both IL and RL, the module includes low-power LED sources. These have lower coherence and no polarization, which reduces speckle-related instability at the power meter. Launch power monitoring gives an IL stability of ±0.02 dB.
Software and system integration
The PCT application runs on the MAP chassis in PCT Max and PCT Lite versions. It offers instrument mode, script (DUT-aware) mode with a results database, and port mapping, and a full set of SCPI remote commands is available over LAN or GPIB. The mORL is often combined with MAP optical switch (mOSW/mISW) and remote optical power meter (mOPM) modules to expand channel count and to verify polarity on multifiber assemblies.
