MGFTY煤礦用光纜結構是：光纖位于帶纖膏的松套管中；纜芯中心是非金屬加強芯FRP（可能會加PE墊層），FRP周圍由松套管、填充繩絞合而成，纜芯內、外的間隙填充纜膏；纜芯外為阻燃護套。
The fibers are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) (may PE blanket) locates in the center of core as a non-metallic strength member. The tubes (ａnd fillers) are stranded around the strength member into a compact and circular core. The cable core is filled with the filling compound to protect it from water ingress. Then, the cable is completed with a Flame-retardant sheath.
光纜芯數范圍：2～144芯
Optical cable core number: 2 ~ 144 core
