GYXTY Center Loose Tube Unarmored Optical Cable G652D Product Description
The GYXTY type optical cable places the 250um optical fiber in a loose sleeve made of high modulus plastic, fills the sleeve with waterproof filler, and adds a water-blocking material to the sleeve to make the optical cable watertight. Two parallel fiber-reinforced steel wires are placed at both ends, and the optical cable is covered with a PE sheath.
