Ensuri ng 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. VIII. Regulatory Compliance Coherent FDR Quadwire® active optical cables are RoHS-6 Compliant. Copies of certificates to be available at Coherent upon request. Quadwire ® active optical cables are Class 1 laser eye safety compliant per IEC 60825-1. The round cable jacket is available in both plenum-rated (OFNP) and riser-rated (OFNR) low smoke zero-halogen (LSZH). IX. Mechanical Specifications Coherent FDR Quadwire® mechanical specifications are based on QSFP transceiver module specifications, substituting the MPO connectors with a cable connecting both ends.
