Losch introduced the SMA500
Connector in 2004 as an improvement to the CuSMA
connector. The internal design and materials are
more closely related to the LD-80 connector, to
improve thermal transfer and heat dissipation.
With higher diode powers, fiber core
overfilling, and output end back-reflections,
the SMA500 connector has allowed laser
manufacturers to increase power thru SMA type
connectors.
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 flexible steel armored cable commonly
referred to as squarelock or interlock cable is
available in outer diameters of 6 and 7mm,
although both smaller and larger diameters are
available. Flexible vinyl coatings adding about
1mm to the diameter are available in clear,
black, 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.
All Losch SMA500 Cables are
custom-manufactured in all core sizes and
configurations, in any length from 1 to 50
meters. Cables are shipped from 1 to 4 weeks
from date of order, depending on quantity and
scheduling.
See “Components” section for SMA500 connector
variations including Keyed SMA and other parts
available for specific requirements. See
Reference Section for power handling
capabilities.
