1. SCOPE
This specification covers the requirements for the optical cable assemblies type QG-BU for CC-Link IE.
※ The Products covered in this specification don’t include the toxic substances in RoHS2.
※ UL’s Wiring Harnesses Traceability program provides traceability for this cable.

2. USE ENVIRONMENT
The cable shall be used in following conditions.
① Indoor pipe ※1② Rack
③ Duct④ Free access⑤ Control box※2※1※2

Available for optical fiber dedicated route.
Allowed if bending radius and storage space allow.

3. LENGTH OF CABLE
The maximum length of the cable is one kilometer.
(The maximum length of the cable with connector is 550 meters.)
