What is the difference between Singlemode and Multimode fiber, and simplex and duplex?
The difference between a singlemode and a multimode cable is their core size. The core is the actual region of the cable which transmits the light (data). In singlemode cables the core is small, with only about 2-9 microns (a micron is a unit of measurement equal to one millionth of a meter). These are best used for applications where there is a longer wiring distance, or high-speed connections. Multimode cables have a larger core (25-200 microns). There are actually 2 different types of multimode cables: 62.5/125 or 50/125. Which one you will need to use will depend on the equipment you are using it in conjunction with. Multimode is better used for connections that are a short distance or a low speed. A simplex cable is just a single strand of fiber, whereas a duplex cable is 2 fibers which are side by side, and connected by their jacket.
