Notes:
1. Assumes no mechanical load force on the unit. Ensuring no mechanical load force requires a cable bend
radius of >105 mm within 100 mm of either cable end module and >60 mm on the rest of the cable.
2. Non-condensing.

NOTE: The Quadwire EDR requires an electrical connector compliant with SFF-8662 or SFF-8672 be used on
the host board to guarantee its electrical interface specification. Please check with your connector supplier.
