APC connectors are commonly used by service providers, or for very long distance transmission. For identification, APC connectors are colored green. These connector types are not interchangeable, so it is very important to verify whether your installation requires UPC or APC connectors. Note that color coding conventions vary by manufacturer, so always make sure to double check your cables and connectors. The general guidelines are:.
This is a very common solution. Again, the type of equipment you are installing will determine your connector needs. Various adapters and patch cable configurations can be utilized to connect fiber optic-based equipment.
Remember, always check the requirements of your installation before purchasing fiber optic connectors. Download your printable copy of the Connector Selection Guide, including all the information in this article plus additional networking examples and images.
Skip to content Choosing Fiber Connectors. Selecting Fiber Optic Connectors There are many different types of fiber optic connector, so choosing the correct one can be confusing. Types of Fiber Optic Connector There are quite a few different styles of connectors. Choosing a Connector Connector style is determined by the equipment that the fiber cable will be plugged into, as well as the type of fiber you are using. The number of plug-in times of the metal connector is longer than that of plastic There are many types of connector signals, in addition to the three introduced above, there are MTRJ, ST, MU, etc.
The optical interface on the transmission equipment side in the industry generally uses SC connector. The SC connector is engineering plastic, which has the advantages of high temperature resistance and not easy to oxidize; ODF side optical interface generally uses FC connector, FC It is a metal connector, but the ODF will not have high temperature problems. At the same time, the number of plug-in times of the metal connector is more than that of plastic. The maintenance of the ODF pigtail is more than that of the optical fiber pigtail.
The pigtail head uses an end face with an inclination angle. The slope is generally invisible, which can improve the quality of the TV signal. The main reason is that the TV signal is analog light modulation. When the coupling surface of the connector is vertical, the reflected light returns along the original path. It was really a "pin vise" holding a stripped fiber. The nose piece is spring loaded and was pushed back when the connector was inserted into a mating adapter.
The fiber stuck out into a drop of index matching fluid on a plastic lens. This solution was state of the art in the late 70s, yielding about 3 dB loss. Above it is the Biconic, the yellow body indicating a SM version.
It started with the fiber being molded into the ferrule. When singlemode versions first appeared, the ferrules were ground to center the fiber core in the ferrule to reduce loss. Since it was not keyed and could rotate in the mating adapters, it had an airgap between the ferrules when mated, meaning loss was never less than 0. Usually MM Biconics had losses of 0. The advent of the ceramic ferrule in the mids in Japan changed the connector designs forever.
The ceramic ferrule was hard and precise. Fibers were accurately located for alignment and ferrules could be allowed to touch. Adding in convex ferrules for PC physical contact between connectors reduced losses to levels below 0.
Below are some more of the popular connectors over the years. More on fiber optic connector and cable color codes. Guide to Fiber Optic Connectors. Check out the "spotters guide" below and you will see the most common fiber optic connectors. All the photos are to the same scale, so you can get an idea of the relative size of these connectors. It has a bayonet mount and a long cylindrical 2. Most ferrules are ceramic, but some are metal or plastic. A mating adapter is used to mate two connectors shown below.
And because STs are spring-loaded, you have to make sure they are seated properly. If you have high loss, reconnect them to see if it makes a difference. This makes it convenient to test, since you can have a set of multimode reference test cables with ST or SC connectors and adapt to all these connectors. See below. Routers are commonly used. MT-RJ: a square optical fiber connector with transceiver integrated, one end of dual fiber transceiver integrated.
Aug 26, Several commonly used optical fiber connectors are described in detail: 1. Generally used on the ODF side most used on the distribution frame 2. Most used on router switches 3.
