Im doing a study for school, and would like to ask your opinion on the best field of study. Or rather, recent trends on the field of telecommunication that would be fun and/or interesting to be my focus.
The big trend right now is metro Ethernet over fiber. What to focus on depends on what part of the system you want to learn. There's not much work as a field installer. Just plug in power, an SFP, and a fiber patch cord and it's pretty much deployed. On the programming side most of the switches are Cisco, Juniper, or Ciena so learning those languages would be helpful; but you'll never use it in the field. Everything is handled remotely.
