Optical fibers (Cont.)
- Used for short or medium distances ( < 2km).
- Cheap compared to other types.
- Supports medium to high bandwidths.
In single mode fibers
- Inner diameter is very small, typically 0.8 to 1 micron.
- Light travels in single mode.
- Used for medium and long distances (> 2km).
- More costly than multimode fiber.
- Can support very high bandwidths (6 Gbps).
