SC APC Duplex Single Mode Fiber Optic Patch Cord 1M Length

Product Description

The acronyms SC, LC, FC and ST refer to the most common types of optical connectors in FTTH applications and data networks. As for the PC/UPC/APC terminology, it refers to the type of polishing applied to the optical terminal (ferrule) which makes possible laser light pulses to cross through two optical fibers.
Then, for example, a typical FTTH pigtail with an SC/APC connector is referring to an SC connector with an APC polishing.

Before you start: A good practice is to keep clean the ferrules tips in order to optimize the optical link. If the connector gets dirty, an optical connector cleaner must be used to get rid of dust and spots.

Detail of an LC optical connector (Lucent Connector or Little Connector)

* “LC” stands for... Lucent Connector or Little Connector.
* A brief history: Developed by Lucent Technologies and released in 1997.
* Features: Push-and-pull fitting (it reminds an RJ45). Safer and more compact that the SC-type, allowing even more density of connectors in racks, panels and FTTH.
* Optical features: For monomode and multimode fibres. Losses of 0,10 dB.

Detail of an ST (Straight Tip) optical connector

* “ST” stands for... Straight Tip.
* A brief history: Developed in the USA by AT&T and used in professional environments such as corporate networks as well as the military field.
* Features: Its shape reminds of the Japanese FC connector, except for its BNC-type fitting system (twist lock also called bayonet style fitting).
* Optical features: For multimode fibers. Losses of about 0.25 dB.
