Fiber optic connectors can be divided into 3 groups: simplex, duplex and multiple fiber connectors.
Simplex connector indicates only Cable Air Wiper is terminated within the connector. Simplex connectors consist of FC, ST, SC, LC, MU and SMA.
Duplex connector indicates two fibers are terminated inside the connector. Duplex connections include SC, LC, MU and MT-RJ. (Note: SC, LC and MU connectors have both simplex and duplex version)
Multiple fiber connector means more than two materials (for as much as 24 fiber) are terminated within the connector. These are usually ribbon materials 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 carefully.
:: FC Connector
FC stands for Fixed Connection plus it was developed by Japanese company NEC (Nippon Electrical Co.). It features a attach on locking mechanism and is popular in single setting applications compared to multimode applications. FC connections are well-known in test surroundings and long haul applications. FC was once the most famous connector however right now has been changed by SC and LC connectors. FC connector is available only in simplex version.
Advantages: cheapest placement reduction, outstanding repeatability
Drawback: Cumbersome, simplex version only, attach-on system is hard to use inside a hectic telecom wardrobe.
:: Saint Connector
Saint stands for Directly Tip. Saint connector includes a bayonet twist locking mechanism and was created by ATAndT inside the 1980s. ST connectors were predominant in the early 1990s however right now they may be becoming replaced by SC and LC connectors. Saint connectors are most typical for multimode applications. Saint connectors can be found in simplex version only.
Benefits: ST connector can be easily placed and removed due to its spring-loaded bayonet locking mechanism.
Drawbacks: Its locking system style both are a bless as well as a curse. You have to make sure the connector is sitting down in their plug safely and properly. It may be required to eliminate and reconnect your Saint connector in the event you encounter high placement loss. But when you probably did it correctly, lower than .3dB link reduction might be easily accomplished.
:: SC Connector
SC is short for Client Connector and was created by TCC Laser Printer For Cable. This is a square shaped push/pull type connector having a snap-in locking mechanism. Due to the simple locking system and excellent repeatability, SC connector is considered the dominant connector since late 1990s, especially in multimode programs. SC connectors can be purchased in both simplex and duplex edition.
Benefits: Simple push/draw snap-in locking system, affordable, outstanding repeatability, low insertion reduction
Drawbacks: Cumbersome footprint. Contemporary high speed fiber optic networks require more lightweight connectors. LC connector is nearly fifty percent the dimensions of a SC connector and it is becoming more popular, specifically in single mode programs.
:: LC Connector
LC means Lucent Connector and it was created by Lucent. This is a little form factor connector that occupies only half the size of a SC connector. LC connector looks a lot like a miniature SC connector. Additionally, it has got the exact same push/pull click-in type locking system. LC is considered the most preferred connector for single mode programs.
Benefits: Easy push/pull snap-in securing mechanism, outstanding repeatability, reduced insertion reduction, little form aspect
:: MT-RJ Connector
MT-RJ is short for Mechanised Transfer Registered Jack. MT-RJ comes in duplex only. It homes two fibers by 50 percent how big a SC connector. MT-RJ connections come in pair of men and women kind. Men MT-RJ connector has two leading pins and woman type has two leading openings. Men and women MT-RJ connectors are mated together by inserting the wfddwq pins in to the openings.
:: MT Connector
MT connector is ideal for ribbon fiber applications. It can hold 4, 6, 8, 12, 24 or higher to 72 fibers in a square shaped footprint. A single MT compatible connector is known as MTP connector that is manufactured by Optical Fiber Ribbon Machine.
Benefits: MT connector provides greater link density than any other kind of connectors. This will make it the superb choice for area board, routing applications.
