The modern world is hinged on internet and telecommunication connectivity. We cannot imagine a world without the internet or telephone/cellphone connections, primarily because most of our daily business is based on connecting with people living hundreds and thousands of miles away. The only way we can conveniently and quickly connect with these people is through these mediums. Therefore, fiber optic jobs are very much in demand these days.
The job itself is something of a challenge since fiber optic engineers often have to brave a lot of rough weather and conditions, climb heights or descend into deep caverns, crawl into cramped spaces, perform a lot of manual labor which involves carrying around heavy tools and material, and perform a lot of repairs and fixes on the cables and poles. That being said, fiber optic jobs allow for a lot of field work and is best suited for people who enjoy working outside and interacting with people.
Quite often, fiber optic engineers spend time working in specific areas as maintenance officials. This means that they rapidly become a part of the community in which they work, allowing them an opportunity to make long-term acquaintances and friends. This is a very rewarding part of their job and perhaps even makes up for the tough working conditions that these folks sometimes have to work in.
Fiber optic jobs can be physically demanding. It puts a certain degree of strain on the physique of the individual and involves braving the environment rather than comfortably sitting in an office chair. However, this is a massively rewarding job for people who want to actually work on the field and engage in traditional engineering work.
