What is an SC Fiber Optic Connector?

Posted by

In fiber optic industry, the SC fiber optic connector stands as a cornerstone of modern networking. It is the most used types of fiber optic connectors in passive fiber optic components or active fiber optic equipment. When you have better understanding about SC fiber optic connector, You have a basic idea to know the fiber optic products.

Let’s take a look at what SC fiber optic connectors elements.

What is SC Short for in Terms of SC Fiber Connector?

The SC (Subscriber Connector or Standard Connector or stick-and-click connector.) fiber optic connector is a type of optical fiber connector known for its push-pull latching mechanism which ensures a stable and secure connection.

Due to its excellent performance, SC is often asseblied as fiber optic pigtail, sc fiber patch cord, even sc outdoor fiber cable. for single-mode and multimode systems. It is also available in a duplex configuration. One cable is used for single-direction communication. For full duplex mode, two cables and two connectors are used in tandem.

Characterized by its square-shaped design, the SC connector is widely used for its excellent performance, ease of handling, and low insertion loss, making it a preferred choice in telecommunications networks and data centers.

The SC connector features a snap-in design with a push-pull latching mechanism that is easy to connect and disconnect. The SC uses a 2.5 mm ceramic ferrule for performance and durability, the same as ST, FC, FDDI, and ESON connectors. The square shape makes the design of the SC more compact and easier to use than its predecessors; however, it is almost double the dimensions comparing the LC connector.

SC Fiber Connector Matings

SC connector is rated for 1000 mating cycles and the insertion loss is only 0.25 dB. The square shape and key features ensure that the correct position is easily obtained when latching. The snap keeps the connector in place, maintaining the optical signal.

SC Fiber Connector Color coding

SC connectors are color coded based on type. Regarding the body colors, it involves the polishing type, briefly, APC for green single mode, UPC for blue single mode or UPC for Grey Multimode.

3 Polishing Types of SC Fiber Connector?

To make SC connectors suitable for different connections, There are 3 main polishing types when assembly SC connectors with fiber optic cables. Putting it all together – An SC connector with an angled polish may be designated SC/APC, or simply SCA while the same connector with a Physical Contact polish is designated as SC/PC. Likewise, that same connector with an Ultra Physical Contact polish is desognated SC/UPC.

Adavatages of Different Polishing from SC Fiber Connector?

When you check the below table, You would get an idea why should be the specific polishing types.

Brief History for SC Connector

Developed in the late 1980s by Nippon Telegraph and Telephone (NTT), the SC connector was engineered to meet the growing demand for more reliable and easy-to-use fiber optic connections. Its design was a leap forward, aiming to replace bulkier and more complex connectors of the time.

The advantages of Using an SC Fiber Optic Connector

At its core, the SC connector is designed for precision. It uses a ceramic ferrule to align fiber optic cables for optimal light transmission. The connector’s push-pull design not only simplifies the insertion and removal process but also minimizes the risk of fiber damage, ensuring a high-quality connection.

SC Fiber Optic Connectors Applications

The SC fiber optic connector has found its niche in various applications:

  • Telecommunications: Used in telephone and cable TV networks, it facilitates clear and reliable signal transmission.
  • Data Communication: Critical for data centers and networking services, SC connectors support high-speed data transfer.
  • Local Area Networks (LANs): In office buildings and campuses, SC connectors are favored for their durability and performance.

Usually SC Fiber Optic Connector is not used alone, It should be assemblied as sc fiber optic pigtail, or sc fiber patch cord etc. see the below:

The Future of SC Connectors

As we stand on the brink of new technological revolutions, such as 5G and beyond, the role of SC connectors remains undiminished. Ongoing innovations aim to enhance their performance, reduce costs, and further minimize insertion loss. The journey of the SC connector, from its inception to its current status as a linchpin of digital communication, reflects the dynamic nature of technology — always evolving, always connecting.

Conclusion

In exploring the depths of what an SC fiber optic connector is, we not only gain insight into a critical component of modern networking but also appreciate the ingenuity behind connecting the world, one fiber at a time.
