Optical Transport Networks Training

Optical Transport Networks Training


Optical Transport Networks are composed of a set of Optical Network Elements connected by optical fibre links to provide functionality of transport, multiplexing, routing, management, supervision and survivability of optical channels carrying client signals. Optical transport networks consist of the networking capabilities and the technology required to support them.

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
