Description: This lab exercise helps to identify the fiber connector types.
1. The below figure shows the different connector types labeled as A, B,
2. The name of the connector types are given as options
3. Drag and drop the name of the connector types into their respective
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
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.
