Indoor simplex optical cable has only one tight sheath (OR LOOS)SM MM-9/125 OS1-OS2-OM1 62.5/125-OM2-OM3-OM4 50/125 optical fiber in the cable sheath. Single-core optical cables are usually classified as interconnect cables and are used for interconnection in front of distribution frames. They are designed for production ends where consistency and uniformity are essential for fast and efficient operation. Simplex fiber optic cables are available in single-mode, multi-mode OS1, OS2, OM1, OM2, OM3, OM4 or polarization-maintaining types to meet the strength and flexibility required for today's fiber interconnection applications. We also offer PVC risers, flame retardant construction and LSZH jackets.
A single fiber consists of a single strand of plastic fiber glass. Simplex signals are sent in one direction. It's a lot like what we call a one-way street. If the signal travels from device A to device B via simplex cable, it cannot return from device B via the same cable.
Single - core cable consists of a single strand of glass fiber or plastic fiber. Simplex optical fibers are most commonly used where only a single transmitting and/or receiving line is required between devices, or where multiple data signals are used (two-way communication over a single optical fiber).
