Both the minEMBc and the DMD-mask measurement techniques were developed part the IEEE 802.

Network Theory
Every homogeneous line defined four parameters which refer unit length and are generally frequency dependant. PVC jacketed cables can made flame-retardant with additives like chlorine and fluorine.

Impedance (wave Impedance, characteristic Impedance)
The impedance line represents the ratio the voltage wave progressing direction the current wave. important that the impedance the cable corresponds with the input-/ output impedance the attached terminals. Just over-filled launch (OFL) bandwidth testing has demonstrated conformance for legacy applications and specifications, laser bandwidth test data provided Dätwyler MMF suppliers can used certify the requirements demanded bandwidth hungry applications used today and the future. The mutual capacitance increases linearly with the cable length.3ae standard. The minEMBc metric, however, the only scaleable measurement technique recognized international standards (In accordance with TIA 455-220 and IEC 60793-1-49) that available transceivers that are compliant with industry standards.

Mutual capacitance (Distributed capacitance C‘)
This the function the line geometry (line line Screen) and the dielectric constant (DK) the insulation. These are the resistance per unit length (conductor resistance) ohm, the distributed inductance Henry, the distributed capacitance (mutual capacitance) Farad and the distributed leakage Siemens. Common values are 100, 120 and 150 ohm. Halogen-free sheath materials don’t contain any halogens! Therefore corrosive gasses are emitted from the cable the event fire, the smoke emission reduced minimum and fire propagation avoided. Chlorine, bromine, fluorine and Astat are the periodic table elements.

minEMBc
The minEMBc-Bandwidth (Minimum Calculated Effective Modal Bandwidth) for determining the minimum laser bandwidth (high data rate capability fibre) differs from the methods used most other multimode manufacturers that rely upon normalized DMD-masks. For higher frequencies the impedance the root over the ratio between the distributed Inductance and the mutual capacitance C’
