Multi-mode fiber (MMF) indoor tight buffer cables are designed for high-speed, short to medium-distance data transmission in indoor environments. The Cables are commonly used in local area networks (LANs), data centers, and enterprise networks. Each individual fiber is coated with a tight buffer layer, which provides physical protection and simplifies handling and termination. The fibers are bundled together and enclosed in a protective outer jacket made of LSZH flame-retardant material suitable for indoor use.
