MGTSV

Mining Applied Fire Resistant Cable

The MGTSV mining optical cable not only inherits all the performance of optical fiber cables, but also adds flame retardant, rodent proof and other characteristics due to the special requirements of the coal mining industry (in special mining environments) to ensure smooth communication and reduce losses.

Color Coding

Bare Fiber	IEC Standard fiber color coding: Blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, aqua Note: ① When the optical fibers in each loose tube is less than 12, they will be colored from the first color (blue) in sequence; ② The fiber color coding can be customized
Loose tube	Standard telecom industry color coding: Blue, orange, green, brown, gray, white, red, black, yellow, purple, pink, aqua T Mark Color Code: Red/Green (from red to green is the arrangement direction of the loose tube) Note: IEC TR 63194:2019 Annex E.2 is the default color coding standard. Color customization is available too.)
