There is a new cable becoming more prevalent in our industry and it is poised to replace the standard RG59 siamese cable. With the enormous increase in popularity of IP cameras over the past three years, we can expect to see a similar trend with fiber optic cable as it comes in two types.
Single mode fiber cable is the most expensive and it carries the highest transmission rate. This is mainly because it is a single strand with only one transmission mode: Very Fast. There is no distortion and thus no overlapping of light pulses. Multi-mode gives you the second highest transmission rate. If you are using it in medium distances up to 2500 meters, you will have optimum transmission speed. When you go over 2500-3000 meters, it is best to use single mode because multiple paths of light will cause distortion at the receiving end.
There are four main reasons that fiber should be implemented if at all possible:
The difference between a fiber optics system and a copper wire system is that fiber optics use light pulses to transmit information down fiber lines instead of using electronic pulses to transmit information down copper lines. Light pulses move easier down a fiber optic line because of a principle known as total internal reflection. Essentially, this principle states that at a certain distance, the light can’t escape the path that it is in…it simply bounces or reflects back into the path. Imagine a very long cardboard tube. Imagine the inner portion or internal cylinder of the tube is mapped in mirrors. Then imagine shining a flashlight through one opening of the tube. Now, if you were to bend the tube around a corner and then another, at the other end of the tube….you would still see the light shine through. Total internal reflection is the law that allows fiber optic networks to transmit data over fiber lines at extreme distances and angles.
