*The above values are distances when cable loss reaches a typical attenuation specified by SMPTE standard at 1/2 clock frequency.
*These values are not equivalent to actual transmission distances, which depends on the equalized distance of receiver.
*Please check with vendor of receiver for equalized distance and reference cable to calculate actual transmission distance.
(*1)Distance may vary depending on conditions. Contact Canare for the proper information.
