Line Buildout (LBO)
Overview
Description The Lucent Technologies Line Buildouts (LBOs) provide an optical transition from
the circuit pack output block to a standard optical connector. The WaveStar OLS
40G circuit packs utilize the Universal type output block and the LBOs referred to
here are those that transition from a Universal block to a standard optical
connector. In addition to providing a transition, the line buildouts or LBOs can
provide from zero to 20 dB of attenuation as an in-line attenuator.
Prior to the development of the WaveStar OLS 40G, there were a few basic
variations in LBOs. With the development of the WaveStar OLS 40G, new
demands were placed upon LBOs for improved attenuation tolerances, higher
power levels, additional granularity, and single-mode to multimode transitions.
This has created several new designs with different properties and applications.
The purpose of this Appendix will be to provide the specifications and suggest
applications for each LBO type.
There are four basic types of LBOs used with WaveStar OLS 40G and they are
identified by the colors white or blue, yellow, green, and gray. Each LBO has its
attenuation value printed in black numerals on its side. Once the LBO has been
removed from its shipping bag, its type can only be identified by its color. In the
field, the distance between the LBO and its shipping bag and the time since
separation is both large and long for this small device. Thus the emphasis on color
identification.
