Nowadays, with the widespread use of fiber optic cables, fiber optic connectors are commonly used together with them in network transmission. After reading this article, we can understand what the fiber optic connector is, what the difference between LC and SC and how we can choose.
- What is the fiber optic connectors?
- Between LC and SC, which one should we choose?
What is fiber optic connector
Fiber optic connectors are an important part of a fiber optic network, used to connect and transmit optical signals between devices. Since it uses light to transmit data, it is less susceptible to interference and can transmit data faster than traditional copper cables, making it widely used in long distance transmission.
Different fiber optic connectors have different coupling mechanisms. Examples include physical size, connector durability and insertion loss. And there are many fiber optic connector type to meet different needs. Among them, LC and SC connectors are most commonly used for fibre optic network transmission.
Fiber optic connector SC
Developed by NTT Laboratories in the mid-1980s, the SC connector was one of the oldest fiber optic connectors. SC connectors are mainly composed of dust caps, connector bousing, inner frames, sub-assembly and boot. And it has a locking tab with push-pull locking for easy connection. It uses ceramic inserts to provide precise alignment and ensure low insertion loss.
LC connector
The LC is the younger product of SC. LC fiber optic connectors have a modular jack-locking structure, which is easy to operate and small in size. It has a great advantage in the case of small space. LC connectors primary consist of dust cap, out housing, crimp sleeves and boot. LC connector can use single mode and multimode.
LC connector is popular in the market for small size and high quality. It is widely used in single-mode and multi-mode transceivers.
How to choose between LC and fiber optic connector SC
Size
The LC connector has a smaller and compact design that features a 1.25mm ferrule. LC connectors are typically used in high-density environments where space is limited, such as in data centers or telecom applications. Their smaller form factor allows for more ports to be packed into a given area, making them ideal for applications that require a high number of connections.
The SC connector is larger and features a 2.5mm ferrule. It is known for its robustness and ease of use, with a push-pull mechanism that allows for simple insertion and removal. SC connectors are commonly used in applications where space is not limited, such as in network switches and patch panels.
Durability
Both fiber optic connectors have the same insertion loss (0.25 to 0.5db for signals or packets) and perform well at very high speeds.
Due to LC smaller size, LC connectors may be more susceptible to damage from frequent plugging and unplugging. You need to use it carefully to ensure that the connectors are properly aligned and locked into place.
The SC connector has a simpler, more robust design. The push-pull mechanism makes insertion and removal straightforward. SC connectors are generally more durable due to their larger size and construction, which helps protect them from physical damage in demanding environments.
Application Areas
LC connectors are often preferred in applications requiring high-density connections, such as in data centers, server farms, and telecommunication systems. Their small size allows for more ports to be packed into a smaller area, making them ideal for high-bandwidth, high-performance networks where space is a premium. LC connector can be used in single mode and multimode.
SC connectors are widely used in applications where durability and ease of maintenance are more critical than space savings. SC connectors are also popular in legacy systems that rely on older fiber optic technologies.
Cost
LC connectors are generally more expensive than SC connectors, primarily due to their smaller size and the precision. Additionally, LC connectors are often paired with other specialized components that increase the overall cost of the system.
SC connectors tend to be more affordable, especially in larger quantities. Their manufacturing process is less complex compared to LC connectors, making them a cost-effective option for many organizations.
Conclusion
In short, If you work in a high-density environment that requires a large number of connections in a limited space, then LC connectors may be a better choice. They offer compact, high performance.
If you need a more durable, manageable and cheaper connection, then SC connectors may be a more appropriate choice.
