Introduction：
The ISN Impedance Stabilization Network model F-110729-1057-1 is an ISN serial product manufactured by FCC (Fischer Custom Communications, Inc.) and authorized for sale by EUTTEST in Shenzhen, China, which complies with the requirements of the latest version of the CISPR32 standard.(math.) genusFor 4 active balanced pairs of Category 5 and Category 5E up to 500 mA per line PoE (1 amp per pair).
CISPR 22/ CISPR 32 defines an ISN as a specialized coupling and decoupling device for the measurement of conducted asymmetrical common-mode radio interference voltages from ITEs.F-110729-1057-1 provides a model for the measurement of conducted emissions from a single, dual, or quad pair of balanced pairs of telecommunication equipment, all of which satisfy the requirements for longitudinal conversion loss, common-mode impedance, phase, decoupling isolation, and voltage dividing factor.
Currently FCC has only this one ISN product, please refer to the following link if you need more specifications of ISN.
