When you are working with fiber optics, you need to be knowledgeable about different fiber connector types. It is crucial because the performance of your fiber optic system heavily depends on the connector you choose. A fiber optic connector can help you to join two or more optical fibers to enable light to transmit from one fiber to another. It is essential to have an in-depth understanding of connector types to choose the best match for your system.
There are various types of fiber connectors such as ST, FC, LC, SC, and MTRJ. Each connector type is unique and designed to suit specific applications. Let’s take a look at some of the common fiber connector types and their features in detail.
ST Connector: The ST or Straight Tip connector is one of the most commonly used connector types in fiber optic cabling applications. It features a keyed bayonet connector utilized to lock to the socket. Its connector tip is straight and aligned with the fiber axis. An ST connector utilizes a twisted bayonet locking system that smoothly attaches and removes from an adapter.
FC Connector: The FC or Ferrule Connector is a threaded connector that needs a rotation of the connector to install or remove. It is commonly used in test equipment and single-mode applications such as telecommunications. An FC connector has a zirconia ceramic ferrule measuring 2. 5 mm in diameter. It provides a reliable connection by aligning the fibers with high precision and repeatability.
LC Connector: The LC or Lucent Connector is a small form-factor fiber connector that uses a 1. 25 mm ferrule instead of the larger 2. 5 mm ferrule typically found in SC and FC connectors. Its smaller size allows for higher port density on fiber patch panels, making it ideal for densely populated data centers. An LC connector has a push-pull latching mechanism for easy and tool-free installation.
SC Connector: The SC or Subscriber Connector is a snap-in connector with a push-pull latching mechanism. It has a square-shaped connector end measuring 2. 5 mm. The SC connector is used for connecting two fibers in telecommunications, LAN, and CATV applications. It also has good temperature and vibration resistance, enabling it to support high-speed data transmission.
MTRJ Connector: The MTRJ or Mechanical Transfer Registered Jack Connector is a multifiber connector that is similar to the RJ-45 telephone connector. It is designed to terminate two fibers within a single connector and uses the same push-pull latching mechanism as the LC connector. An MTRJ connector has two fibers, a transmitter, and a receiver, integrated into a single connector to enable duplex transmission. It is also smaller and lighter than most other connector types, enabling easy cable management when space is limited.
Conclusion
Fiber connector types play a crucial role in the performance of your fiber optic system. Choosing the right connector type is crucial to ensure optimal performance and prevent data loss. Properly matching the connector type according to cabling infrastructure, bandwidth, signal frequency, and distance requirements affects the performance of your fiber optic system. Each fiber connector type has unique features that enable reliable and efficient data transmission. You should choose the one that best suits your application. Whether it’s the ST, FC, LC, SC, or MTRJ connector, understanding the fiber connector types can help you pick the right one for your fiber optic system.
