MGXTSV-12B single-mode optical cable MGXTW-8B flame-retardant optical cable for coal mines

Single mode or multi-mode optical fibers are inserted into a loose tube made of high modulus material, filled with a thixotropic waterproof compound inside the loose tube. A layer of plastic coated steel strip (PSP) is longitudinally wrapped around the loose tube, and a water-resistant material is added between the steel strip and the loose tube to ensure the compactness and longitudinal water-resistance of the optical cable. Two parallel steel wires are placed on both sides, and a flame-retardant polyolefin sheath is extruded,MGXTSV-8B mining flame-retardant optical cableThe outer sheath is made of blue flame-retardant polyvinyl chloride.

MGXTSV mining flame-retardant optical cableSpecification Model

The MGXTSV-8B mining optical cable layer twisted core usually includes a central reinforcement component, a loose fiber twisted layer (including possible filling ropes or signal lines), and zip ties, etc; The core of the central tube type optical cable is a loose tube; The loose tube includes multi-core single-mode or multi-mode optical fibers, filled with a thixotropic composite or placed with a solid water-resistant material

Fiber optic cables should be composed of single-mode or multi-mode fibers of the same type. Depending on the specific requirements of the user, they can be made into a mixed single-mode and multi-mode fiber optic cable, and the number of cores should meet the requirements of the cable specifications.

The surface of the optical fiber coating layer should have a full-color code, which should comply with GB6995.2 and not fade or migrate.

The performance indicators of single-mode optical fiber should comply with the provisions of GB/T9771. The performance indicators of multimode optical fibers should comply with the provisions of GB/T12357.

The coated optical fibers in the optical cable should be placed in loose tubes made of thermoplastic materials, and the remaining length of the optical fibers in the loose tubes should be uniform and stable. The number of optical fibers in each loose tube should not exceed 12 cores.

The size of the loose tube should specify the outer diameter and wall thickness of the tube, with a nominal outer diameter of 1.6~3.0mm and a tolerance of no less than ± 0.1mm. The thickness should increase with the outer diameter, with a nominal value of 0.30~0.50mm and a tolerance of no less than ± 0.05mm. The nominal size of the loose tube can vary with the number of fiber cores in the tube, but it should be the same in the same optical cable.

Identification using full chromatography

The colors of the coated optical fibers inside the loose tube should be different, and their colors should be selected from the various colors specified in Table 1. It is allowed to use the natural color instead of one of the colors in Table 1 without affecting recognition.

Loose tubing should have identification color codes, which should comply with GB6995.2 regulations and not fade or migrate. These color codes should be full-color, but can also be circular or strip-shaped.

The loose tube material can be made of polybutylene terephthalate (PBT) plastic or other suitable plastics, and PBT should comply with YD/T1118.1 regulations.

In filled and semi dry optical cables, the gaps inside the loose tube should be continuously filled with a thixotropic paste like composite. In fully dry optical cables, a solid water-resistant material should be placed in the gaps inside the loose tube.

MGXTSV-8B mining optical cable filling composite and water blocking material (including water absorption) should be compatible with other adjacent optical cable materials, and should not damage the transmission characteristics of the optical fiber and enable
