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.

Electrical Characteristics (TOP = 0 to 70C, VCC = 3.3 ± 5% Volts)
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.

Regulatory Compliance
Finisar Quadwire EDR Active Optical Cables are RoHS-6 Compliant. Copies of certificates
to be available at Finisar Corporation upon request.
Quadwire EDR Active Optical Cables are Class 1 laser eye safety compliant per IEC
60825-1.
Standard fiber cable type is round-section construction, plenum-rated. Other cable types can
be supported upon request such as LSZH, round-section construction.
VIII. Mechanical Specifications
The Quadwire EDR mechanical specifications are compliant with the QSFP28 transceiver
module specifications (as defined in SFF-8661), substituting the MPO12 receptacle with a
fiber optics cable connecting both ends.
