The Major Impact of a Tiny System

Unraveling the Ferrule of Fiber Fast Connectors

Producing high-quality fiber fast connectors requires more efforts and attention compared to other connectors. For instance, selecting high-quality ceramic head ensures precise alignment of the fibers, while using high-performance matching gel effectively fills the tiny gaps between the fibers. Additionally, the critical step of end-face cleaning during assembly helps eliminate small contaminants, reducing the risk of product failure. However, simply considering these aspects is not enough. A finely designed ferrule system plays a more crucial role in the reliability of the fiber
connectors.

Mechanical Principles of
the Ferrule System

When installing the connector on-site, the bare fiber is guided
into the ferrule along the Micro-groove. As the fiber fills the
Micro-groove, it lifts the upper Cover slightly. By toggling the
Locking Ring, downward pressure is applied to the Cover,
securing the bare fiber firmly in place and achieving a stable
connection with the embedded fiber within the ferrule.
In practical application, the retention force of the ferrule system
on the bare fiber should be ideally controlled between in narrow
range of 2 to 3N. It can lead to poor fiber contact which cause
increasing of the connector's attenuation and signal interruption
if the force is too low. This issue is particularly problematic
under vibration. On the other hand, excessive pressure can
cause fiber glass deformation, increasing signal attenuation. In
the worst scenario, it may damage the fiber, leading to
transmission disaster failure.

What Has SANYUAN Been Doing for A Reliable & Durable Ferrule System?

Controlling the retention force of the bare fiber within an optimal range significantly depends on a reliable ferrule system, for SANYUAN fast connectors, every detail is precisely tailored and engineered. This includes the depth of the Micro-groove, the thickness of the cover plate, and the width of the Locking Ring, etc. Each component is crafted using high-precision molds to maintain consistency between the design and the real-time product, high-quality virgin PEI as the material for ferrule is selected to ensure sufficient hardness and strength across a wide temperature high and low cycling.

SANYUAN’s meticulous attention to design, material choice, and production precision, all ensures that our connectors meet the rigorous demands of high-performance fiber connections even under the harsh application environment, offering users a dependable and efficient installation experience.
