The LD-80 Connector was developed by Losch in 1994
to be compatible with the 4 x 10mm industrial
Interface Standard and the Mitsubishi D-80
fiberoptic cables. The extremely accurate Losch
LD-80 connector allowed for plug-and play
connections without system re-alignment, as well
as lower cost cable repolish and repair costs.
Low OH- and High OH- fluorine-doped silica
clad fiber with the standard 0.22NA (numerical
aperture) are inventoried in core sizes from 100
to 1000 microns. Silica cladding thicknesses
range from 20 to 40 microns for effective
waveguides from the UV to near IR. GI (graded
index) fiber is also available. See
Reference
Section.
Losch uses silica fiber coated with silicone
and nylon for high power applications. The
low-index silicone (1.39) performs as both a
protective coating and secondary waveguide to
channel cladding modes to the output end of the
fiber.
The standard cable has a flexible steel
armored cable commonly referred to as squarelock,
with an outer diameter of 8mm, although both
smaller and larger diameters are available. The
green flexible vinyl commonly indicates fiber
with an SI (step-index) fiber. Yellow vinyl
jacketing is used to identify cables with GI
(graded index) fiber, and custom colors are also
available. If cables are to be subjected to low
vacuum applications, or are to be AR
(anti-reflective) coated, bare cable is
recommended.
Unique to the Losch cables are the round
metal “cuffs” in black or colored anodized
aluminum that attach the cable to the connector.
The Cuffs permit removal of the LD-80 connector
for repair and also an area for laser-engraving
of a company logo or ID.

capabilities of LD-80 Cables.
