This research work studies the temperature e ects in W-shaped core refractive in-dex optical ber. The work designs an optimized W-tailored optical ber (OWTOF) that checks the e ect of rising temperatures in W-tailored optical ber (WTOF) for better communication. Initially, an introduction to the general concept of optical bers including tailored optical bers (TOF), temperature e ects and models is pre-sented as a background. This is followed by studies on existing literature on optical bers where a gap is identi ed. The gap is that; temperature rise in communication bers is challenging the use of tailored bers through unnecessary distortion and delay in information. Also, ber design is limited in scope because of existing design practice. Thus the need to optimize bers for better communication. To ll in this gap, a three stage optimization process is designed and a methodology for achieving this optimization for the bene t of telecommunication systems and services is presented. Here, a regularly varying function is introduced in the geometry of WTOF for the temperature parameter leading to the design of the OWTOF. Finally, analytical and numerical simulations covering the performance of the OWTOF in relation to WTOF are stated and proven. Additionally, six re- search questions and remarks are answered. A major result of this work shows that the OWTOF is a better ber for controlling temperature rises than the WTOF at a propagation distance around one unit. Hence, better suited for communication with- out distortion and delay compared to WTOF in this region. Finally, the research work concludes with three recommendations for improving this work for better com- munication.
