SC Fiber Connector, or square connector, is a push-pull fiber optic connector with a 2.5mm ceramic ferrule that utilizes a locking tab to secure the cable. SC connector was originally developed as an alternative to the ST connector. It is the most common fiber optic connector type used today. It is known for its push-pull latching mechanism. SC connector is available in both single-mode and multi-mode versions. In addition, it is also available in duplex configuration and conforms to the TIA/EIA 568B.3 standard. Easy to use and quick to install. Meanwhile, it is durable and has low insertion loss. SC fiber connector is widely used for datacom and telecom FTTH applications.
History
The SC Connector is a fiber optic connector released by NTT in the mid-1980s. It was originally developed as an alternative to the ST connector. Initially used in Gigabit Ethernet networks, the SC connector was adopted by the TIA-568-A specification in 1991. It was also the first one chosen as the standard connector for TIA-568-A. With improved materials and manufacturing processes, the manufacturing cost of SC connectors has gradually decreased. It has dominated the fiber optic field for more than 30 years and is currently one of the two most common fiber optic connectors.
Feature of SC Fiber Connector
Push-pull latching mechanism
SC connectors use a push-pull latching mechanism. This mechanism securely locks the connector in place, ensuring a stable connection. In addition, the internal precision alignment mechanism can accurately align the optical fiber core. Our SC/APC Field Assembly Fast Connector has excellent Zirconia ferrules and a finely made metal V-groove. It guarantees a very reliable connection for a variety of network applications.
Low insertion loss
SC connectors have low insertion loss, typically less than 0.5 dB, which is important for maintaining signal integrity over long distances.
Dimensions
The SC connector has a large outer dimension of approximately 20×10×40mm. Compared to other small connectors, the SC connector occupies a larger space.
Durable
SC connector shell is made of durable plastic material. It can withstand external vibration and impact and is suitable for various complex environments.
Compatibility
SC connectors have a standard 2.5 mm size. So, it is compatible with various equipment, such as FC or ST connectors.
Advantages and Disadvantages of SC Fiber Connector
The disadvantage of using an SC fiber connector is the size of its ferrule. It requires more space than a smaller connector like the LC fiber connector. However, the SC connector has many advantages.
Ease of Use
SC connectors have a square shape for the ferrule. Therefore, it is more compact and easier to use than previous products.
Easy to connect and disconnect
The SC connector features a snap-in design with a push-pull latching mechanism. Its sturdy hold prevents connection problems.
Reputation
The SC connector is popular with businesses thanks to a proven track record of over 30 years.
Less cost
With improved materials and manufacturing processes, the SC connector is now less expensive than the ST connectors.
Terminate Methods of SC Fiber Connector
There are several methods to terminate SC fiber connectors. There are Splicing, Heat-cured epoxy, and Prepolished/splice connectors. Each of these methods has its advantages and disadvantages. It is important to follow the correct method for your particular application. Also, it is important to follow the proper procedure to avoid any damage to the connector.
Splicing
Splicing is the most common method of terminating fiber optic connectors. Generally, splicing is used in outside plant applications, such as restoration of damaged or deteriorated fiber. It is also used in long cable runs, especially in OSPs. This method is also used to mix different types of cables.
Heat-cured epoxy
One popular method is to use a heat-cured epoxy. The advantages of this method are low cost, quick installation, and high reliability. In addition, it’s easier to use than a cold cure method, which takes more time and skill. The epoxy is cured in an oven for about five minutes. Most of these ovens are powered by AC, but some operate on battery power.
Pre-polished/Splice connectors
Pre-polished/splice connectors are ideal for fast terminations. They have angled physical contact and can be used for high-quality optical connections. Using these connectors can save installers time and effort.
Tips for using SC fiber connectors
There are a few tips when using SC fiber optic connectors.
Clean regularly
Dust and dirt can affect the connection quality of SC fiber connectors and may even cause interruption of optical signal transmission. Therefore, the ferrule and socket of the SC fiber connector should be cleaned regularly. In addition, when the SC connector is idle, a dust cap should be used to protect the connector port to prevent dust and dirt from entering.
Avoid excessive bending or pulling
Excessive bending or pulling of the SC fiber connector may cause damage. Therefore, please ensure that the bending radius of the optical fiber meets the requirements and avoid excessive stretching.
Reduce connections and disconnections
Frequent connection and disconnection of connectors will cause connector wear. Therefore, it is necessary to reduce the number of unnecessary connections and disconnections as much as possible. In addition, a protective cover should be used to protect the connector.
Avoid collision
Collision may cause damage to the SC connector or loose connection. Therefore, please ensure the fiber connector is properly fixed to avoid external impact.
In Conclusion
SC fiber connector is a popular choice in telecommunications networks and is known for its push-pull latching mechanism, which makes it easy to install and use. It is the most common fiber optic connector type.
