Which connector type is known to have the best or lowest reflectance?

The SC-APC connector type is recognized for its low reflectance characteristics due to its angled physical contact design. This angle helps to minimize the reflection of light that can occur at the interface of the connector, resulting in optimal performance for high-bandwidth applications and long-distance communications.

In contrast to standard connectors like SC, LC, and ST, which have a flat polish and can cause greater reflection, the SC-APC’s angled design is specifically engineered to reduce the return loss. This is incredibly beneficial in fiber optic applications where signal integrity is paramount, as excessive reflection can lead to increased loss and interference in signal transmission.

The use of SC-APC connectors is particularly common in applications that require precise and high-fidelity data transfer, such as in telecommunications and data centers. This makes them a preferred choice when low reflectance is essential for system performance.
