Hi Friends,
Today i will try to share my experience and learning about optical and electrical interfaces. As in transport we have number of equipments from IP RAN to LRAN and from HRAN to Core which have optical and electrical interfaces. I will try to clear some of the basics doubts regarding the basis difference between them and channel capacity requirement and cost associated with each of them.
1 Basic difference- As shared in last post when electrical pulses to represent binary 1s and 0s then the interface is electrical interface. Electrical signals need medium to travel like any other pulse . And optical interfaces use pulses of light to represnt the signals as one and zero.
2. Channel Capacity- As we all know from our engineering subject , when we have less attenuation then S/N ratio is much better , Optical always have good S/N ratio as compared with electrical medium so channel capacity is much larger in case of optical as compared to electrical.
3. Cost - Opticals interfaces are costly as compaired with electrical interfaces.
Generally we can say these are the basic differences between the optical and electrical interfaces in terms of very basic terms.
I will share more observation and finding from my experience in transport and main terminology from the RAN and IP networks part.
