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 internalspecifications.

1VibrationObject:Examination of following components, receptacle NO12FDW-A, opticalCON MTP® NKO12* 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 NO12FDW-A were mounted. The front side was mated with aNKO12SA-A-0-10 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.

2Dust

Object:Variations of attenuation due to massive dust penetration. The test was accomplished with single mode
cables where pollution on the fiber is much more critical as on multimode fibers
The test was carried out by an independent laboratory: Electrosuisse, test laboratory PQ/PIK in 8320
Fehraltorf, Switzerland.
Test Set-Up:
The opticalCON MTP® connector was exposed to dust from both sides in wired condition for 60 minutes.
The built-in sealing shutters protected the optical conductor at the front side, the plugged-in LC-Duplex
connectors shielded the rear side.

The maximum difference between initial and after dust measuring of the insertion loss at 1.550nm is 0.11dB.
Additional visual inspection of the ferrule surface couldn’t indicate essential soil remains.
Figure 2.a and 2.b exhibit two opticalCON chassis
NO12FDW-A with silicon gaskets SCDP*. On the rearside there are standard single-mode LC/LC patch cablesplugged. To avoid dust on the ferrules, the unconnected
LCs are sealed with a plastic bag.

figure 2.afigure 2.bAfter dust test: The opticalCON MTP® chassis NO12FDW-A are completely covered with talcum particle on
the front and rear side (fig. 2.a ). The measured attenuation (figure 2.b) establishes only small variation of
the attenuation values after dust test.
