More introduction of optical fiber adapter?
by www.fiber-mart.com
The adapter is mainly in the optical fiber exposure in the implementation of the same or different fiber optic connector connector, so that under very little loss in the implementation of smooth flow. It fits the two sections of the fiber precisely so that the light energy emitted by the emitted fiber can be coupled to the receiving fiber to the maximum extent and minimizes the impact on the system due to its involvement in the optical link.
Usually we say the adapter, also known as fiber coupler, fiber optic flange, fiber optic connector. AC, FC, SC, ST, LC, MU, MPO and other types of connectors, including FC, SC, ST, LC is currently on the market commonly used in four kinds of joints, SC, LC can do duplex adapter, and LC duplex Adapter with more.
This section will guide you how to distinguish between different adapters, and how to quickly select the desired product by appearance color.
(1) connector type
AP / UPC, LC / UPC, LC / APC, FC / UPC, FC / APC, ST / UPC, where APC, UPC refers to the shape of the fiber end (grinding method).
Connector type, model characteristics, material, advantages
SC standard square joints, plastic, high temperature, not easy to oxidation
LC square connector, smaller than the SC connector half, plastic, high temperature, not easy to oxidation
FC standard round connector metal, repeatability and durability
ST with key lock lock structure, metal repeatability and durability
Grinding method
UPC connector cross section is flat
APC oblique 8 degree angle polishing
“/” Indicates the type of fiber adapter adapter that applies. “/” Behind that fiber optic fiber cross-section process, that is, grinding method.
(2) the appearance of color distinction
SC, LC adapter: UPC is blue, APC is green, this is the color of the product ontology. FC adapter: UPC is red, APC is green, this is the color of the product dust cap. ST adapter: UPC is yellow, this is the color of the product dust cap.
