Details of Single Mode Fiber Patch Cord
Single Mode (SM) fiber, conforming to the G652D standard. This type of fiber is widely used in long-distance and high-speed optical communication systems due to its low dispersion and attenuation. The cable has a diameter of 2.0mm and uses LSZH (Low Smoke Zero Halogen) material for the jacket, length in 15m. LSZH is flame-retardant, emits minimal smoke and no toxic halogens when burned, making it suitable for indoor environments with high safety requirements.
The connectors D4-D4 feature a metallic ferrule and a cylindrical design, ensuring precise alignment for single-mode fiber connections.
The patch cord features a bright yellow cable jacket, which is a common color for single-mode fiber cables, facilitating easy identification in wiring environments.
