Experience
Amphenol?s cable assembly expertise dates back to the first industry standard connector
(SMA), over 25 years ago. As new fiber optic connectors have entered the industry,
Amphenol has carefully selected the most robust and reliable connectors to participate in
their design and development. Our in depth understanding of connector design, and the
complete control of connector materials, make Amphenol cable assemblies one of the

Complete Testing
Performance testing is one of Amphenol?s fundamental strengths. Connector and cable
materials are extensively inspected prior to assembly. Every cable receives 100% inspection
for both insertion loss and visual defects (under 1200X video magnification).
Interferometers are used for accurate endface geometry testing.

In order to produce high quality, reliable cable assemblies, there are a number of physical characteristics that must be addressed. Many of
these issues have been thoroughly outlined in IEC, EIA/TIA, JIS and Telcordia standards. They include acceptable parameters for
intermateability, insertion loss, return loss, radius of curvature, apex offset and fiber height. Other issues that attribute to long term
reliability are ferrule/fiber fit, ferrule concentricity, and ferrule surface defects. The following diagrams illustrate some critical components
of a fiber optic cable assembly.

variations in core diameter.
Height
Surface Defects - Visual defects are one of the most common
causes of latent failures. Scratches, pits, and chips in the ferrule end-
face can change over time, becoming more pronounced and migrat-
ing to critical areas of the fiber core, thus affecting
performance. They are also a prime source for deposits of dust,
moisture, and other contaminants. Photo not to scale. Features exaggerated.
Radius of Curvature - The endface of the connector is given a
apex
specific radius during the polishing process. This radius provides the
offset
basis for ensuring that both fibers make contact. Both the apex offset
Apex Fiber
and fiber heights are dependent on the radius of curvature being
within the predetermined parameters.
Fiber Height - Physical contact of the fiber is necessary for proper
light transfer. The end-face geometry has strict fiber protrusion limits,
as well as fiber undercut limits. These limits are based exclusively on
a mathematical calculation of the radius of curvature. If the fiber is
too high, damage to the endface may occur. If the fiber is too low,
the physical contact may never occur, causing increased attenuation
