Bookham, Inc. (BKHM) Wrap Up:

We design, manufacture and market optical components, modules and subsystems that generate, detect, amplify, combine and separate light signals principally for use in high-performance fiber optics communications networks. Due to its advantages of higher capacity and transmission speed, optical transmission has become the predominant technology for large-scale communications networks. Innovation at the component level has been a primary enabler of optical networking, facilitating increased transmission capacity, improving signal quality and lowering cost. Optical communications equipment vendors initially developed and manufactured their own optical components. For a variety of industry-related reasons, the majority of optical equipment vendors have sold, eliminated or outsourced their internal component capabilities and now rely on third-party sources for their optical component needs.  ...
