Fiber Optic Training in Multan , Pakistan , Dubai
This course has been developed with 1.5 month of classroom learning and 15 days of hands-on skills labs, review, and certification testing time. The labs provide the practical understanding and skills required to properly design, install, and maintain fiber optic networks. Students can attend the first two-days of this course either in person, or online via our instructor-led.
This course is applicable to anyone working with fiber optic communications systems in telco/broadband, premises, traffic, rail applications, and more. Students will learn how to splice, connectorize, test, and troubleshoot optical fiber networks to increase efficiency, reliability, and on-the-job safety as well as reduce cost and downtime.
