Supply GAOTANG fiber optic attenuator, fiber optic coupler Chiping

Fiber coupler is detachably (active) connection between the optical fibers and optical devices, the two end faces of the optical fiber which is precise docking to the light-emitting optical output power can be coupled into the receiving fiber to maximize the go, and an optical link it to intervene in order to influence on the system is minimized. For the waveguide fiber coupler, generally a component having a Y-branch optical signal from the input of an optical fiber it can be used to decile. When the open-angle coupler branch road increases, the cladding leakage light will increase so as to increase the excess loss, so open angle is generally less than 30 °, thus the length of the waveguide fiber coupler can not be too short. The serial port or other interface module into an optical fiber interface. Points multimode fiber conversion and single-mode fiber conversion. General multimode fiber converter for distances up to 4KM; singlemode is 40KM. Singlemode multimode can mutual conversion, multi-machine communications, relay conversion networking functions.
