What are the different iOLM options available and what are their uses?


Full details of all the option combinations and platforms/modules supported can be found on the iOLM specification sheet which can be downloaded via the following link.

Please find below some additional information on the various options.

1. iCERT

iCERT is available for singlemode and multimode fiber testing, the iCERT pre-defined test configurations provide quick access to the latest industry pass/fail thresholds to automatically certify cable installations in data centers and enterprise.

A video overview is also available via the following link:

2. iLOOP

With iLOOP you can test two fibers at once with a simple loopback jumper and reduce your testing time by 50%. This feature is very useful in field applications such as DAS/FTTA and other projects where there is a large number of fibers to test (for example Data Centers).

iLOOP allows you to perform unidirectional and bidirectional iOLM loopback measurements, which consist in looping two fibers together at one end to test both of them at once. Unidirectional loopback measurement test both fibers at once and evaluate them separately, whereas bidirectional loopback measurements pair two measurements automatically (A to B and B to A) and then generates the directional measurement for the two fibers.

3. iADV

iADV is a bundle that contains the following options.

            3.1 Realtime

Allows you to directly from the iOLM application interface to activate the ODTR laser in continuous shooting mode and adjusts parameters without stopping or returning to submenus. The trace refreshes in real time, making it possible to monitor the fiber for sudden changes. Perfect for a quick overview of the fiber under test, distance to an identified break, to control field splicing or to check for obvious impairments before launching an iOLM thorough characterization.

            3.2 Advanced SOR trace support

iOLM manages an unrestricted number of acquisitions for optimal link characterization; Simply input the pulse width, averaging time and wavelength(s) for the SOR file report to add it to the results package, you can also review the SOR trace right in the iOLM application

            3.3 2:N

2:N allows characterizing 2:N splitters with a clear pass/fail verdict for multi-input or redundancy networks. The iOLM identifies 2:N splitters, as well as both of their input branches, allowing users to accurately document the network with one test.

           3.4 iOLM expert mode

Specifically designed for the fiber test expert or manager requiring more flexibility in documenting the trace files for reporting purposes.

            3.5 Optimode: SFP safe troubleshooting

Ideal for point-to-point troubleshooting when an SFP might be connected on the far end of a link. When technicians are dispatched on-site, they are still unaware of what is wrong and may accidentally damage a transceiver with an uncontrolled pulse width. This solution prevents this risk and guarantees no damage to the SFP while troubleshooting.

4. iPRO

The iPRO option includes both iADV and iLOOP feature sets along with Multifiber MPO cable characterization and troubleshooting (iMF). 

In combination with an external 1 x12 MPO EXFO switch, the iOLM allows for faster testing of a singlemode MPO cable, with no need to use a fan-out cable or cassette, thus reducing errors during testing.
