※ The Products covered in this specification don’t include the toxic substances in RoHS2.

2. USE ENVIRONMENT
The cable shall be used in following conditions.
Indoor
① Indoor pipe ※1② Rack
③ Duct④ Free access⑤ Control box ※2※1
Available for optical fiber dedicated route.
※2
Allowed if bending radius and storage space allow.
Outdoor① Pipe (underground) ※1, 3② Rack ※4③ Trough ※3, 5※3Possible even if not submerged※4
Code part is impossible※5
Possible when external force is not applied by protecting the bent part and the contact part3. LENGTH OF CABLE
The maximum length of the cable is two kilometer.
(The maximum length of the cable with connector is 550 meters.)
