The best fiber-optic connectors are military-grade connectors. These connectors satisfy the MIL-C ST specifications and are corrosion-proof; have isolated relief boots to reduce cable strain; and are heat, shock, vibration, fungus, and salt-spray resistant. In this post, I am going to talk about the 10 computer networking concepts that every professional should master.
I will also include links to the main articles of each concept. And generally speaking, the difference between LC and SC fiber optic connector lies in the size, the handling and the connector history, which will be discussed respectively in the following text. Present and future communication technology demand fast, efficient and safe performance in the data communication process.
Large and complex databases all interconnected must be able to receive and transmit data without outside interference. Both SC and LC are designed to achieve such a kind of transmission. SC has a larger connector housing and a larger 2. LC has a smaller connector housing and a smaller 1. The SC is ideally suited for datacoms and telecoms applications including point to point and passive optical networking. Considered by some to be the modern replacement of the SC connector; its introduction was less successful, in part due to initially high license fees from inventor Lucent Corporation.
Also a push-pull connector, the LC utilizes a latch as opposed to the SC locking tab and with a smaller ferrule it is known as a small form factor connector. With the introduction of LC compatible transceivers and active networking components, its steady growth in the FTTH arena is likely to continue.
The FC was the first optical fiber connector to use a ceramic ferrule, but unlike the plastic bodied SC and LC, it utilizes a round screw-type fitment made from nickel-plated or stainless steel. Initially intended for datacoms and telecoms applications, its use has reduced since the introduction of the SC and LC.
These deliver similar performance to the FC but both have less expensive components and are quicker to connect. However, the screw-on collet of the FC does make it particularly effective in high vibration environments, ensuring that the spring-loaded ferrule is firmly mated. At a glance they can be mistaken for one another but the ST uses a bayonet fitment rather than a screw thread.
Usage has declined in recent decades, for the same reasons as the FC. Additionally it cannot be terminated with an angled polish, which limits use in single mode fiber and FTTH applications.
Deployed predominately in multi-mode datacoms it is most common in network environments such as campuses , corporate networks and in military applications where the quick connecting bayonet had its advantages at the time. The general guidelines are:. This is a very common solution. Again, the type of equipment you are installing will determine your connector needs. Various adapters and patch cable configurations can be utilized to connect fiber optic-based equipment.
Remember, always check the requirements of your installation before purchasing fiber optic connectors.

Selecting Fiber Optic Connectors There are many different types of fiber optic connector, so choosing the correct one can be confusing.
Types of Fiber Optic Connector There are quite a few different styles of connectors. Choosing a Connector Connector style is determined by the equipment that the fiber cable will be plugged into, as well as the type of fiber you are using.
Fiber connectors are designed specifically for the type of fiber you are using. Are you installing single mode or multimode fiber? If you are installing single mode fiber, the most common connector type will be UPC blue. If your equipment specifically requires APC green , you must install all angled polish connectors.
