Answer:
Single-mode cables include one glass strand (the core), surrounded by three layers of other material (the cladding, the buffer, and the jacket). They are relatively more expensive than other cables. Single-mode cables can transmit data at fast speeds over long distances (up to 62 miles) and offer higher bandwidths.
Multi-mode cables have more than one strand and transmit light along many paths. They support very fast speeds of between 10 Mbps to 10 Gbps over short distances (2,000 and 1,000 feet, respectively). Although these cables can transmit data over short distances, they will distort data over long distances.
Plastic optical fiber cables consist of plastic fibers instead of glass fibers. They are cheaper than glass optical fiber cables. They are similar to multi-mode cables; however, they are only reliable over short distances.
