ABSTRACT: Broadband, high bit-rate, lightwave communication systems are increasingly being deployed in the public telecommunications network. At
the same time, the public network infrastructure is evolving and expanding into the so-called information superhighway. This is
expected to provide end-to-end transport not only for traditional voice traffic, but also for nontraditional information traffic such
as two-way, interactive, on-demand, data, video, wireless, and other information services. Some of these services are being provided
by the computer industry and others are being provided by the consumer industry. The convergence of these industries is
resulting in equipment of different, unknown or unsuitable technology, design life and reliability performance, being considered for
deployment, co-location and interworking with traditional telecommunications equipment.
This Special Report (SR) consolidates generic reliability concerns associated with lightwave devices to serve as an "aide-memoire"
when evaluating these devices for use in public telecommunications network applications. The specific reliability performance will, of
course, depend on the particular materials, design, and fabrication processes used.
