Fiber optic connectors can be separated into 3 groups: simplex, duplex and multiple fiber connectors.
Simplex connector indicates only FTTH Cable Production Line is terminated within the connector. Simplex connectors consist of FC, ST, SC, LC, MU and SMA.
Duplex connector means two fibers are terminated in the connector. Duplex connectors consist of SC, LC, MU and MT-RJ. (Note: SC, LC and MU connections have each simplex and duplex version)
Several fiber connector means more than two fibers (for approximately 24 fiber) are terminated inside the connector. These are generally ribbon materials with fiber count of 4, 6, 8, 12 and 24. The most famous ribbon fiber connector is MT connector.
Now let’s analyze every type of connector closely.
:: FC Connector
FC is short for Fixed Connection and it was made by Japanese company NEC (Nippon Electric Co.). It possesses a screw on locking system and is also very popular in solitary setting programs compared to multimode programs. FC connections are well-known in test surroundings and long haul programs. FC used to be the most popular connector however right now will be changed by SC and LC connectors. FC connector is available only in simplex version.
Advantages: lowest insertion reduction, excellent repeatability
Disadvantage: Bulky, simplex edition only, screw-on mechanism is hard to use within a busy telecom closet.
:: Saint Connector
Saint stands for Straight Tip. ST connector includes a bayonet perspective locking system and was developed by AT&T within the 1980s. ST connectors had been predominant in the early 1990s however right now they are becoming replaced by SC and LC connectors. Saint connectors are most common for multimode programs. Saint connections are available in simplex edition only.
Benefits: Saint connector can easily be placed and eliminated because of its spring-loaded bayonet securing mechanism.
Disadvantages: Its locking mechanism style both are a bless along with a curse. You have to make certain the connector is sitting down in their socket securely and properly. It may be necessary to eliminate and reconnect your Saint connector in the event you encounter high insertion reduction. But if you did it correctly, under .3dB link loss could be effortlessly accomplished.
:: SC Connector
SC stands for Subscriber Connector and was made by Secondary Coating Line. This is a square shaped drive/draw type connector having a click-in locking system. Due to the easy securing system and ideal repeatability, SC connector is considered the dominant connector since late 1990s, specifically in multimode applications. SC connectors are available in each simplex and duplex version.
Benefits: Simple push/draw snap-in locking mechanism, inexpensive, outstanding repeatability, low insertion reduction
Drawbacks: Cumbersome footprint. Modern high-speed fiber optic networks need more compact connectors. LC connector is practically fifty percent how big a SC connector and is gaining popularity, specifically in single mode programs.
:: LC Connector
LC is short for Lucent Connector plus it was created by Lucent. It is a little form factor connector that occupies only half how big a SC connector. LC connector looks much like a miniature SC connector. Additionally, it provides the exact same push/pull click-in kind locking system. LC is one of the most favored connector for solitary setting applications.
Benefits: Easy drive/draw snap-in securing mechanism, outstanding repeatability, low insertion loss, small form factor
:: MT-RJ Connector
MT-RJ is short for Mechanical Transfer Registered Jack. MT-RJ is available in duplex only. It houses two materials in two how big a SC connector. MT-RJ connectors can be found in kind of male and female type. Male MT-RJ connector has two leading pins and female type has two guiding holes. Male and Female MT-RJ connections are mated together by inserting the wfddwq pins in to the openings.
:: MT Connector
MT connector is ideal for ribbon fiber programs. It can hold 4, 6, 8, 12, 24 and up to 72 fibers within a square formed footprint. One MT suitable connector is called MTP connector which can be manufactured by Optical Fiber Coloring Machine.
Benefits: MT connector provides much higher connection density than any other kind of connectors. This makes it the superb option for area panel, routing programs.
