why did we name Ciena Equipment as Ciena 5160/Ciena 3930/Ciena 6200/Ciena 6500/Cinea 5400 ?? what is the reason behind these numbers ??
What a good question.
Ciena uses four digit numbers to identify its products. The first two digits denote the product family, and sometimes we use the second two digits to describe the product variant. So we use 3900 and 5100 for Ethernet switches intended for the edge and aggregation layers in the network. 6500 is a family of packet-optical transport boxes.
Now the question of why we use the number 6500 for packet-optical transport boxes is a good one. I'm afraid there isn't a specific logic to the numbering. The numbers are chosen to be distinctive (not used by other manufacturers), although there are some collisions on products with a long history. There are also cultural implications, for example 8 is a lucky number in Chinese culture, and 7 is a lucky number in western culture.
So when we have a new family of products, we spend a lot of time trying to make sure we choose a good number, testing it with teams around the world.
Subham, thanks again for asking this question, and Simon for sharing a bit more about the meaning behind the numbers.
