Fiber optic connectors can be split into three groups: simplex, duplex and multiple fiber connectors.
Simplex connector means only Cable Air Wiper is terminated inside the connector. Simplex connections include FC, ST, SC, LC, MU and SMA.
Duplex connector means two materials are terminated within the connector. Duplex connectors consist of SC, LC, MU and MT-RJ. (Note: SC, LC and MU connectors have both simplex and duplex edition)
Several fiber connector indicates a lot more than two materials (for as much as 24 fiber) are terminated inside the connector. These are usually ribbon fibers with fiber count of 4, 6, 8, 12 and 24. The most common ribbon fiber connector is MT connector.
Now let’s analyze every type of connector closely.
:: FC Connector
FC is short for Repaired Link and it also was made by Japanese company NEC (Nippon Electrical Co.). It possesses a attach on securing mechanism and is more popular in single setting applications when compared to multimode programs. FC connections are popular in test environments and long haul applications. FC was once the most popular connector however right now has been replaced by SC and LC connections. FC connector is available only in simplex version.
Advantages: cheapest placement reduction, outstanding repeatability
Drawback: Cumbersome, simplex edition only, attach-on system is hard to function within a hectic telecom wardrobe.
:: ST Connector
Saint means Straight Tip. ST connector has a bayonet twist locking mechanism and was created by ATAndT in the 1980s. ST connections were predominant in the early 1990s but now they are being changed by SC and LC connectors. ST connections are most common for multimode programs. ST connections can be found in simplex edition only.
Advantages: Saint connector can be easily inserted and removed because of its spring-packed bayonet locking system.
Disadvantages: Its securing mechanism style both are a bless and a curse. You must make certain the connector is sitting down in the socket safely and properly. It may be necessary to eliminate and reconnect your Saint connector if you encounter high placement loss. But when you did it properly, less than .3dB connection reduction might be easily achieved.
:: SC Connector
SC stands for Subscriber Connector and was made by FTTH Cable Production Line. This is a square formed drive/draw type connector with a snap-in securing mechanism. Because of its simple securing system and ideal repeatability, SC connector is one of the dominant connector because late 1990s, specifically in multimode programs. SC connections are available in both simplex and duplex edition.
Benefits: Easy push/draw click-in securing system, inexpensive, excellent repeatability, low placement reduction
Disadvantages: Bulky footprint. Contemporary high-speed fiber optic systems require more lightweight connectors. LC connector is practically fifty percent the size of a SC connector and is also becoming more popular, specifically in single mode programs.
:: LC Connector
LC means Lucent Connector and it was created by Lucent. It is a small form aspect connector that occupies only half the size of a SC connector. LC connector looks much like a miniature SC connector. In addition, it provides the exact same push/draw click-in kind securing system. LC has become the most preferred connector for single mode applications.
Benefits: Simple push/draw click-in securing system, outstanding repeatability, reduced insertion reduction, small form aspect
:: MT-RJ Connector
MT-RJ stands for Mechanised Transfer Registered Jack. MT-RJ comes in duplex only. It houses two fibers in two how big a SC connector. MT-RJ connectors come in set of male and female type. Men MT-RJ connector has two guiding pins and female type has two guiding holes. Male and Female MT-RJ connectors are mated with each other by plugging the wfddwq pins to the holes.
:: MT Connector
MT connector is designed for ribbon fiber programs. It can hold 4, 6, 8, 12, 24 or higher to 72 materials within a square formed footprint. One MT compatible connector is known as MTP connector which can be manufactured by Cable Air Wiper.
Benefits: MT connector provides much higher connection density than any other kind of connectors. This will make it the superb selection for area board, routing applications.
