Graded-index multimode fiber (gi-mmf)
| Fiber Optic Glossary |
A type of multimode fiber where the refractive index of the fiber core decreases radically towards the outside of the fiber. four types of gi-mmf have been specified in iec 60793-2: legacy om1 (62.5/125) and om2 (50/125) fibers and the newer, high bandwidth, laser-optimized om3 and om4 fiber (both 50/125), designed for vcsel lasers and gigabit data rates

Single-mode fiber (smf), английский
A type of optical fiber specified by the itu as g.652 (standard), g.652d (low water peak), g.657 (bendinsensitive), and g.655 (nonzero dispersion shifted). g.652 and g.652d fibers are also specified by the iec 11801 standard as os1 and os2 fibers
Tight buffered cable, английский
- A type of cable with internal 900-micron coated fibers, such as breakout and distribution styles. jacket materials vary but they are normally rated for indoor use to meet plenum, riser, and lszh requirements
- A protective coating extruded tightly over fiber for mechanical and environmental protection. the coating material is either nylon or pvc. this buffering offers excellent physical and flexing properties, but higher micro-bending sensitivity.
