Fiber optic adapter Fiber optic adapters are also known as fiber couplers and fiber optic flanges.It mainly implements the docking of the same or different fiber optic connectors in the fiber exposure, so that the optical path is smoothed with little loss.It precisely pairs the two sections of the fiber so that the light energy output from the transmitting fiber can be coupled to the receiving fiber to the maximum extent and minimize the impact on the system due to its involvement in the optical link. The fiber optic adapter series includes: FC. SC. ST. LC and so on. The plug interface can be divided into PC, UPC and APC according to the grinding method. Widely used in optical distribution frames (ODF). Optical fiber communication equipment, instruments, etc. .
AdapterFC/APC(alloy):The external reinforcement method is a metal sleeve, the fastening method is a turnbuckle, and the butt end of the ceramic pin is used.The connector has the advantages of simple structure, convenient operation and easy manufacture, but the fiber end face is sensitive to fine dust, and Fresnel reflection is easy to occur, and it is difficult to improve the return loss performance.Later, improvements were made to this type of connector, using a mating pin with a spherical end face, resulting in a significant increase in insertion loss and return loss performance. Technical Specifications: ·Pin interface end face mode:APC ·Pin size:2.5mm ·Material:alloy ·Insertion loss:APC≤0.45dB ·Return loss: APC≥60dB ·Operating temperature:-40ºC~+70ºC ·Connector plugging durability life>1000times
