Trends in information and communication technology are creating great opportunities for engineers with the skills to work as optical network engineers. The growing demand for bandwidth continues to push optics into many realms of communication networks. Optical networking now dominates global communication networks, terrestrial long-distance networks, and metropolitan area networks. Optics is also displacing other technologies in access networks, local area networks, data centers, mobile backhauling, and even in short-distance applications like server backplanes. The success of 5G mobile communications will depend to a large extent on the availability of fiber optic backhaul networks.
This trend will continue unabated for as long as optics offers the most communication bandwidth of any other technology. As a result, optical network engineers are expected to remain relevant for a long time to come. This article is intended as a guide for those who want to learn more about beginning or expanding their careers in optical networking.
What is an Optical Network Engineer?
An optical network engineer is a highly skilled technology professional responsible for the planning, designing, implementation, or maintenance of an optical network.

How do you build a career as an Optical Network Engineer?
Getting a job and growing into a career as an optical network engineer requires a combination of education, relevant training courses, knowledge of specific vendor systems, experience, and other career activities. The following steps are typical for a successful career in optical networking:
Get a Bachelor's Degree
Most employers expect candidates for the position of an optical network engineer to have completed a Bachelor's Degree. While the degree itself may not prepare you for the specific position you will end up with, it demonstrates a commitment to a career in a technology field. It also demonstrates your capacity to learn new skills on the job.
Employers are not only looking for your current subject matter knowledge but your capacity to learn new skills on the job. Most engineers find out that they learn more about the subject matter of their position during their first few months on the job than during their entire four years in college. Typical areas of study are optical engineering, electrical engineering, information technology, physics, and other STEM subjects. Employers may also choose to substitute education for years of experience as a technician in IT, telecommunications, or other closely related industries.
Take vendor-neutral training courses in Fiber Optics and/or Optical Networking
Whether you are still looking for a job or you just landed one as an optical network engineer, you must take vendor-neutral courses related to your job function. A vendor-neutral course is developed and delivered by organizations that are not affiliated with a supplier of fiber optics or optical system equipment. These offer unbiased, well-rounded content that can give you the basic knowledge required of successful optical network engineers. Vendor-specific courses, on the other hand may be designed to focus only on certain topics where the vendor has a competitive advantage.
If you are searching for a position, a certificate in optical networking will not only show. your commitment to the field, but will also demonstrate your depth of subject matter knowledge. This gives you a competitive advantage over other candidates vying for the same position.
If you are already on the job you can expect the company to arrange for you to take relevant courses for your career development. However, you own your career and the onus is on you to initiate the training you require. Do some research, find out the most appropriate training courses and recommend them to the training department in your company.
In large companies, training departments have responsibility for a wide range of subject areas, including management and sales. You will be more knowledgeable about relevant available courses for optical network engineers than they are. The onus is on you to bring this to their attention and have the course included in the company training program. Following is a semblance of valuable vendor-neutral optical network training courses.

Take other employer-sponsored courses
Most employers will offer a wide range of training courses to give you the skills you need to do your job. Courses may include training on vendor equipment and systems that you use.
Employers may only offer such training to employees if they deem it absolutely necessary for their jobs. If you feel that such a course will be required for your chosen career path, you should bring it up to your management. Managers may not want to offer you skills that will only benefit their competition once you decide to leave the company. You should be prepared to persuade them of how the training will benefit your current company.
Attend relevant conferences
Attending conferences is one of the best activities you will undertake to build your career in optical networking. The industry is changing rapidly and conferences will keep you abreast of the ever-changing technologies. You will learn about industry trends, find out about new optical fibers and transmission systems, gain some new skills, and make a lot of new professional connections.
