The SC/APC-SC/APC reference coupling from Softing IT Networks serves as a connection element for fiber optic cables with SC/APC connectors. It enables the optical coupling of two fiber lines in the singlemode range, where the APC end faces (Angled Physical Contact) ensure minimal reflection and high signal quality. This coupling is specifically designed for use in networks requiring high transmission quality and low attenuation, for example in telecommunications or industrial applications.

Functions and equipment in detail
The coupling connects two SC/APC connectors and serves as a reference point for measurements or as a transition element in fiber installation. The use of APC connectors ensures an angled end face finish, which reduces reflections in the fiber core and thus enhances signal integrity. The coupling is designed for use in fiber optic networks based on singlemode fibers and supports data transmission over short to medium distances with high bandwidth.

Technology explained simply
The SC/APC connector is a standard in fiber optic technology, providing a secure and precise mechanical connection. The APC designation stands for Angled Physical Contact, meaning the fiber end face is angled at 8° to minimize reflections at the connection point. This is particularly important in systems transmitting sensitive signals, such as in optical communication. The coupling itself is designed to precisely center the two connectors and establish a stable optical connection.

Compatibility and accessories
The coupling is compatible with all SC/APC connectors that meet common industry standards. It can be used in existing fiber installations to stabilize connections or serve as a measurement point.

Installation and mounting
Installation is performed by simply inserting the two SC/APC connectors into the coupling. The mechanical fit ensures a secure connection without additional fastening elements. Mounting requires no special tools, as the connector itself provides a secure connection.

Advantages in operation
The use of the SC/APC-SC/APC reference coupling results in reduced signal reflection and thus improved signal quality. The mechanical stability of the connection ensures reliable performance, even under frequent plugging and unplugging. The coupling is therefore suitable for applications requiring high availability and low failure rates, such as in network centers or industrial communication systems.
