AEM Announces Optical Time Domain Reflectometry (OTDR) Testing Capability.


Tempe, AZ, 23 March 2023  AEM, a global leader in test innovation, today announced availability of OTDR testing capability for their multifunction TestPro and Network Service Assistant (NSA) test platforms.

With the new OTDR test adapters, AEM’s TestPro provides additional troubleshooting functionality along with Tier-2 certification capability.  The OTDR gives technicians in the field the ability to easily pinpoint the location of broken fiber or other loss events causing an optical loss test to fail.

“TestPro provides the most comprehensive coverage for practically all test needs of cable installers, ranging from CAT5e through CAT8 copper cable certification, tier 1 certification for singlemode and multimode fiber, and now tier 2 fiber certification with introduction of OTDR adapters,” said Harshang Pandya, General Manager for Precision Cable Test. “Our customers get convenience and cost savings from being able to choose any test functionality with small detachable test adapters.  Beyond the testing itself, our customers can manage all types of test reports for a project seamlessly using our TestDataPro report management software which now also supports OTDR test reporting.”

The OTDR test adapters are available in new product kit offerings, and for existing customers, these adapters can be purchased as a standalone adapter that can be added to any TestPro or Network Service Assistant.  A complementary firmware update for the test platform is required and can be downloaded through MyAccount section of the company’s web site.

New test kits include TESTPRO K21E-MM, TESTPRO-K21E-SM, and TESTPRO-K21E-QD are OTDR-only test kits. TESTPRO-K41E provides full tier-2 fiber certification capability including loss, length, and OTDR for both singlemode and multimode cables. TESTPRO-K71E is a super-technician kit that includes copper and tier-2 fiber certification, together with Multi-Gig, PoE, and network test capabilities.  For existing customers of TestPro or Network Service Assistant, the standalone test adapter model numbers are AD-OTDR-MM, AD-OTDR-SM.
