Abstract

This paper examines several possible deployment variations in near-term Fiber-In-The-Loop (FITL) network architecture from a reliability perspective. The reliability impact of network topology is modeled and compared to current Bellcore availability objectives. The study indicates that careful consideration of network architecture before deployment can minimize service unavailability. However, aggressive efforts to improve equipment/media reliability are crucial in achieving the availability objectives; these efforts should be focused on the distribution segment of FITL architecture, which is estimated to produce the largest contribution to overall downtime. Results also indicate that present availability objectives for various network elements need to be re-allocated under FITL to reflect more accurately the relative reliability of FITL hardware and media.
