A cutover is the controlled process of transferring live network traffic from an existing (legacy) fiber infrastructure to a new one. This guide covers every phase — from initial planning through execution to post-cutover closeout — with the step-by-step procedures used on live fiber networks. Day-of. What is fiber optic cable cutover Cutover: Literally, cut first and then connect. I am a wireless communication agent, and I have done several cutovers. It is an honour to present you with the latest version, which is another example of how ITU-T is bridging the standardization gap. The fibre optic project management process encompasses all project phases from initial civil works through optical fibre installation to final network commissioning—a structured FTTH project management approach coordinates permitting, construction execution, splicing operations and quality. This unit describes the skills and knowledge required to modify an infrastructure to cutover new cables into an existing indoor and outdoor, domestic, commercial or industrial cabling installation including communications applications in telephony, broadband, data, video, radio frequency (RF). The invention relates to a cut-over method of a communication optical cable line strip system. The method comprises the following steps of: removing a new optical fiber cladding or a protective covering; cleaning the surface of a naked optical fiber; accessing a new optical fiber after an old.
