Single-mode fiber optic adapter SM SC/APC simplex ALANTEC FOA-SCA-SMS

Single-mode fiber optic adapter SM SC/APC simplex by ALANTEC is a key element in the construction and maintenance of reliable fiber optic networks. It is used for precise connection of fibers terminated with SC/APC connectors, finding application in switches, subscriber outlets, and connecting patch cords with pigtails spliced to the fiber optic cable. The choice of the right adapter directly affects the quality of transmission and minimizes signal loss.

Characteristics and application

This adapter, manufactured by the renowned company ALANTEC (part of A-LAN Technologie), is characterized by high precision and provides a stable connection. SC connectors, due to their ease of use (snap-in) and compact size, are one of the most popular solutions on the market. The single-mode SM SC/APC simplex adapter is particularly useful in applications requiring minimization of back reflections, thanks to the angle of the end face polishing being 8 degrees (APC - Angled Physical Contact). This solution is crucial in high-bandwidth networks such as FTTH (fiber to the home) or CATV networks. The simplex design means that the adapter allows the connection of a single optical fiber – an ideal solution for devices requiring data transmission in only one direction.

Advantages and benefits

• Minimization of signal loss: APC angled polishing reduces back reflections, which translates to higher transmission quality and network range.
• High connection repeatability: The adapter provides stable and repeatable connections, which is important for network reliability.
• Durability: Made of high-quality materials, it guarantees long-lasting and trouble-free operation – confirmed by over 1000 connection/disconnection cycles.
• Wide operating temperature range: The ability to operate in the range of -40°C to +85°C makes the adapter suitable for use in various environmental conditions.
• Simple installation: The snap-in mechanism facilitates quick and intuitive installation and removal of the adapter.
• Precision: Ferrule diameter of 2.5 mm ensures precise fit and minimal insertion loss at 0.15 dB.

Construction and parameters

The SM SC/APC simplex adapter is characterized by a solid construction ensuring connection stability. The use of plastic (excluding the ferrule) provides lightness and corrosion resistance. It is important to remember about proper pairing – SC/APC adapters should only be connected to other SC/APC connectors to maintain optimal transmission performance. The use of APC connectors in single-mode networks is particularly important due to the reduction of back reflection noise, which allows for achieving greater bandwidth and data transmission range.
