![]() Here is a helpful fiber optic connector types chart for your reference. Manufacturers and distributors are more likely to have equipment to accommodate SC and ST style connectors than any other connector style.įiber Savvy stocks your fiber connector needs with, LC Connectors, SC Connectors, ST Connectors and MTP/MPO Connectors. There are a number of connector styles on the market including LC, FC, MTP/MPO, and SC Connectors, which are the most popular connectors. But depending on the project field assembly may be preferred. Some manufacturers will assemble the connectors onto the fiber cable before distributing the cable, making it a quicker and easier install. Of the many different fiber connector types, connectors for both glass fiber cable and plastic fiber optic cable are available. High quality connectors prevent misalignment and air gaps between fibers, minimizing the reflection or loss of signal. Connectors match up the fibers from the cables so they are aligned and allow light to pass through and continue signal transmission. The fiber optic connector terminates the end of a fiber optic cable and offers quicker connection and disconnection compared to splicing.

In this way, we saw the difference between SC and ST optical fiber connectors. SC connector is mostly used for router switches, and large core switches with fiber uplinks whereas ST connector is mostly used for optical fiber distribution frames. SC is the most used design due to its simplicity, cost-effectiveness, and less chance of damage as compared to ST design which is less used. SC connector is made of plastic mold whereas ST connector is made of ceramic mold. Parameter SC Connector ST Connector Physical Design Push-pull coupling Bayonet-style coupling Shape Square or Rectangular Round Connector Size Compact Larger than SC Ferrule Diameter 2.5mm 2.5mm Typical Insertion Loss 0.25 dB 0.3 dB Typical Return Loss >50 dB (for UPC) >25 dB Ease of Use Easier due to push-pull Requires aligning and twisting Application Telecom, datacom, CATV Industrial, military Polishing Type PC, UPC, APC PC Durability High Moderate Number of Connections Single or Duplex Generally Single Cost Moderately Priced Generally Less Expensive Here’s a table that compares the SC and ST Optical Fiber Connectors. Difference between SC and ST Optical Fiber Connectors It comes with a spring-loaded sheath that holds the fiber in place. This means you have to rotate it until tight and rotate reverse to remove it. It has round ceramic ferrules and bayonet locking features. ![]() Instead of a latch, it uses a lock method for a secure connection to the port. It is a plastic molded body of square shape, with a push-pull locking technique. The cables are joined with the connectors through the slicing method. These interfaces are a must for connecting to the communication ports. In the case of optical fiber cables, there are generally four types of connectors used – FC, LC, SC, and ST. Due to this reason, some form of suitable connector must be interfaced with the cable end so that it is connected to the respective communication port. This is then not possible for them to connect directly to any communication port. Similar to every type of cable that we use, they initially come in raw form (without connectors). Now that we have understood the use of optical fiber cables, we will see why connectors are required. Why are Optical Fiber Connectors Required? This makes travel faster and more efficient to communicate. Ethernet data from CAT6 cables is converted into light form from binary form before travel, then transmitted to a far distance, and received back in binary form on the receiver side. ![]() As light is the fastest mode of travel, optical form is the best way to communicate data. For this reason, optical fiber hardware cables are used.Īs the name implies, it works on light travel to convert data into optical form and transmit it. You know that 100 meters is not enough if you want to transfer data from one location to a very far location. Though Ethernet is the fastest mode of communication protocol, the cable (CAT6) that is used to carry it can cover only the distance mentioned. When you use a standard Ethernet cable, whether straight or cross, it can cover only a distance of 100 meters.
