Subject:
Mechanical and optical tests applied to the opticalCON® transmission
system for Pro Audio / Video industry purposes with main focus onchanges in attenuation.
Optical performance is being examined with regard to attenuationand its variation vs. environmental and mechanical conditions.
This documentation describes the results of the test series conductedat Neutrik AG and University of Applied Sciences of Technology
Buchs NTB.

The tests were carried out in accordance with the IEC-Standard
main groups IEC 60794 and IEC 61300 as well as to Neutrik internal
specifications.

Vibration

Object:Examination of following components, receptacle NO24FDW-A, opticalCON MTP® NKO24* cableconnector. The intention of the test was to determine their attenuation in a fiber optic system and theperformance before, during and after the vibration test.
The test was carried out by an independent laboratory: NTB, “Interstaatliche Hochschule für Technik
Buchs” division “Labor Mess- und Simulationstechnik” located in Buchs / Switzerland.
Test Set-Up:
For the vibration test 6 receptacles NO24FDW-A were mounted. The front side was mated with aNKO24M-A-0-15 opticalCON MTP® cable. The rear end was connected with the test instrument via
precision measuring cables (fig. 2.a).
The applied test set-up complies with IEC 61300-2-1:2004.

Test Results:
Measurement during vibrations showed no variation in attenuation. The locking mechanism withstands
this extreme vibration without any problems, i. e. no separation or functional deteriorization occurred.
