Fiber-optic Adapter and Attenuator
Fiber optic adapters (also called couplers) are designed to connect two fiber optic cables together. Fiber optic adapters are the most used optical passive devices in optical fiber communication systems. Most fiber optic adapters are composed of three parts: two optical fiber connectors and a coupler. Two fiber connectors are installed into the two fiber ends; the coupler plays the role of aligning the sleeve. In addition, the coupler is often equipped with metal or non-metal flanges to facilitate the installation and fixation of the connector.
Fiber optic attenuators, as an optical passive device, mainly used in fiber optic to debug optical power performance and optical instrument calibration correction and fiber signal attenuation to ensure the optical power in a stable and desired level in the link without any changes on its original transmission wave.
