Product details
The FT-3915 from F-tone Networks is a single-fiber 62.5/125 um multimode sensor cable with a PTFE (Teflon) jacket for high-temperature service. A stainless steel flexible tube inside provides strong crush resistance, while aramid yarn and stainless steel braiding reinforce the cable against tensile loads in rugged installations. The PTFE jacket tolerates elevated temperatures and harsh chemical exposure beyond what standard polyethylene insulation can handle. The cable operates across -60 to +85 degrees C and supports fiber temperature sensing in environments up to 150 degrees C, making it suitable for high-temperature communication and temperature monitoring installations.
Key Features
- 1 fiber, 62.5/125 um multimode
