Identifying Different Fiber Optic Connector Types

Previous   |    Next

Description: This lab exercise helps to identify the fiber connector types.

Instructions :

1. The below figure shows the different connector types labeled as A, B, C, D.

2. The name of the connector types are given as options 

3. Drag and drop the name of the connector types into their respective places

Explanation:

The correct answer for this lab is as shown below

1. ST connectors: These connectors are the most common type of commercial fiber optic connector. These connectors utilize an exposed plastic tube housing the optical fiber. This requires a connection to a matching cable on the other side, incorporating a connector that mates to the other. These combine in a spring-loaded twist, reminiscent of BNC connectors, and are noted for their reliability. ST connector is very popular in communication applications, such as LANs and CCTV systems.

2. SC-Connector: SC is short for Subscriber Connect is one of the most frequently used connectors. Used in fiber-optic networking, it has caps to prevent laser light reaching eyes. The connector usually in pairs (transmit and receive), often clipped together. connectors have the ferrule that houses the fiber mostly concealed. Probably the most similar commercial equivalent of To slink, SC connectors does not require a mating cable on the other side. Instead, these snap-on connectors simply push into their jacks with a click. SC connectors use a push-pull design and can be used for simplex or multiplex applications

3. FC connector: It is similar to ST connectors, these fiber optic connector’s screws into their mating jacks. Additionally, the tube surrounding the optical fiber is typically shrouded in ceramic or metal, as opposed to being fully exposed. The inner ring of the connector is keyed to ensure positive mating to its corresponding jack. FC connectors are primarily used with single mode fibers and used in telephone, instruments, and high-speed communication links. The style is similar to that of an ST connector, but it uses a threaded connection which makes it better suited for high vibration environments 

4. LC cables: latch and release into their jacks in a manner similar to Ethernet connectors. Smaller in form than SC connectors, their durability is not compromised, nor is cost increased. Instead of snapping or thermo forming the connector to the cable, it is glued. This makes it a popular connector for field use. LC connectors are used in private and public networks, and are gaining in popularity due to their small form factor (SFF) optical transmitter/receiver assemblie 

LC connector is a miniaturized version of the fiber-optic SC connector. It looks just like the SC, but is half the size with a 1.25 mm ferrule instead of 2.5 mm. 1000BASE-FX should use SC, ST, LC, MTRJ or MIC connectors with SC being the preferred option.

Usually, cable modems use F-type female connector to connect to the broadband provider. 

ST (Short for Straight Tip) connectors, and SC (short for Subscriber Connect) connectors are typically large connectors. MT-RJ, and LC (short for Local Connector) have small form factor, and allow higher port density. These connectors (MT-RJ and LC) allow higher number of fiber optic connections in a smaller area, and hence desirable when there are a large number of fiber optic terminations to be made.
