The Viavi FBPP-BAP3 narrow barrel assembly contains a common set of optics that can be used with multiple hollow tips. This approach makes many common tips more economical. Some tips contain their own optics and do not require a BAP. Typical examples of tips containing optics are long-reach tips and tips with a 60-degree angle for hard-to-reach areas; RibbonDrive tips, such as those used for MPO connectors, are another example.
