As a starting point, I offer this link/list of companies in the optical networking space...
Message 12272950
I have pasted below along with my annotation (P) of which are public as of 2/10/00...some commonly known...others based on successful symbol lookup...many in the access world are not yet public...thx to tpboxster for this info...
I invite others to add/update as appropriate.

The Four Categories of Optical Networking
There are four broad categories of optical networking products:
LONG-HAUL TRANSMISSION: As described above, this category focuses on moving data and voice traffic across long distances, usually several hundred kilometers. One challenge unique to long-haul transmission is amplifying the signals periodically to make sure they arrive at their destination with the same intensity and integrity as when they were sent.
WIDE-AREA OPTICAL CROSS-CONNECTS (sometimes also called bandwidth managers): These solutions focus largely on switching signals between the long-haul segments, such as taking a signal that arrives in Boston from San Francisco and routing it to Atlanta. These products also provide long-distance signal protection and restoration, as well as path secretion.
METROPOLITAN AREA NETWORKS (MANS): This emerging category of optical networking is responsible for receiving signals from the long-haul networks and parsing them out to enterprises and individuals and vice versa. Originally, metro networks were envisioned as miniature versions of long-haul networks. As this paper outlines, however, this assumption is completely off track.
ACCESS: As the name implies, this category concerns itself with access to data and voice signals by end users. The access level is necessarily the most fragmented of the four categories, because it must accommodate the disparate telecommunications needs of users in homes, offices, factories and so on. In addition, solutions at this level ripple upwards, altering the ways in which long-haul and metropolitan networks must operate. For example, wiring a neighborhood or office complex for high-speed Internet connections leads to changes throughout the network to accommodate the new access demands.
