Advanced multimode fiber for high-speed short-reach interconnect

In this paper, we describe the characteristics of advanced MMF, how it is specified, how it is manufactured, and update its application in IEEE P802.3ba 40G/100G SR4/10 standards development.

Bend insensitive fibers for FTTH and MDU

As deployment of fiber to the home (FTTH) within multiple dwelling units (MDUs) is growing, more technicians will be involved in the deployment of optical drop cables, and there is a desire to use craft and practice similar to what is used for copper cables. We introduce a solid bend insensitive fiber in this application that is backwards compatible to G.652D fiber, and has macrobending, splice loss and system performance to meet the very demanding conditions of these applications. A closer look at the demands of this environment has made it necessary to re-evaluate reliability in these critical applications. We apply the Power Law Model to predict reliability in these demanding applications, and provide experimental evaluation of the model through testing on optical fibers and cables. It will be shown that bends and tension need to be considered together when evaluating the reliability of the passive optical plant.

Specialty high bandwidth multimode fiber for optical interconnection

In this paper, we review high bandwidth multimode fiber and their role in upgrade path of optical interconnection to 40G and 100G in data centers and high performance computing.
