Intelligent Optical Link Mapper—iOLM


Intelligent Optical Link Mapper—iOLM

Using automated multipulse acquisitions and advanced algorithms, the iOLM is an OTDR-based application that delivers detailed information on every element on the link, in a single-button operation—providing maximum intelligence and simplicity for expert-level link characterization.

KEY FEATURES

  • Self-setting unit
  • Link-Aware technology
  • Optical Link View
  • Prompt diagnosis
  • Consolidated bidirectional link view (patent-pending)
  • OTDR trace fi le generation (.sor)

KEY NETWORK APPLICATIONS

  • Point-to-point access
  • LAN/WAN, enterprise and data centers
  • FTTx/PON MDU
  • Mobile backhaul (FTTA/DAS)
  • Metro core and long-haul
  • CWDM
  • Cable testing (IL/ORL measurement)

GO BEYOND OTDR TESTING.

Innovation is front and center at EXFO, and the Intelligent Optical Link Mapper (iOLM) is a prime example of a game-changing solution. The iOLM lets you take advantage of the full power of your OTDR, bringing automation to a new level—and enabling even the untrained technician to become a test expert in no time.

The iOLM integrates all our expertise into a simple, easy-to-use software that will take your OTDR testing capabilities further than they’ve ever been. And since EXFO designs and optimizes each OTDR model so that it offers the best possible performance for its specific application, your solution will fit to your reality.

ADDITIONAL FEATURES

Real-Time OTDR Mode

The iOLM supports real-time OTDR mode (RT option) functionality via the iOLM software application. Either run the OTDR application (Oi option) or the RT mode (RT option) to measure field-splicing or to check the link before launching an iOLM acquisition.

2xN Splitter Characterization

The iOLM is the only solution on the market to characterize 2xN splitter with a clear pass/fail verdict for multi-input or redundancy networks. It identifies 2xN splitters as well as both their input branches allowing users to accurately document the network with one test (compared to three tests when using traditional methods).

iOLM Expert Mode (iEX)

iEX is a software option specifically designed for the fiber test expert or the manager who requires more flexibility in documenting the trace files for reporting purposes. Because flexibility also means that you can create your own elements to better match your network plans, this option allows you to add extra events, delete events or re-analyze the trace.

RECOMMENDATIONS

Angled-Polished (APC) Connectors

Like any OTDR, the iOLM will be impacted by strong reflections at the unit’s port. To ensure low reflections and maintain measurement accuracy, the iOLM singlemode port must be used with APC connectors. Another advantage of using APC connectors is their ability to handle harsher conditions without becoming highly reflective while maintaining the unit’s performance.

In the case of UPC connectors, they are prone to be highly reflective if contaminated, worn or damaged. This will affect the measurement and will lead to premature connector replacement. Although testing a UPC network does not require a UPC unit, using an APC/UPC test jumper (included with the iOLM) or a launch fiber (SPSB) ensures compatibility.

Test Method

EXFO recommends using a 150-meter launch cable (SPSB) to exclude the loss of the iOLM’s connector or to allow UPC network testing. It will also extend the instrument’s connector life by reducing the number of matings—ultimately improving the cost of ownership.
