Optical attenuator is one of the passive components, which is generally used in equipment testing, connection between equipment, connection between jumpers, etc., to attenuate the optical power of the optical link, so as to obtain the optical power value of the target.

Introduction of Yin Yang attenuator:
The male and female fixed attenuators are connector type at one end and Adapter Type (called Yin Yang type) and the attenuation value is not adjustable. LC optical attenuator is one of the common attenuators LC, SC, FC and ST. It is mainly used in the attenuation of optical power in the optical link, so as to obtain the required target optical power value. At the same time, it is used in the distribution frame or equipment that needs to save space. LC optical fiber male and female fixed attenuator mainly includes LC/A PC Slope 8 degrees and LC/ UP C There are two kinds of zero end faces. Generally, APC corresponds to the green frame, and UPC corresponds to the blue frame. The attenuation value of LC optical fiber attenuator has great selectivity. It can be selected from 0 to 30dB, and can be applied to the interval wavelength of 1250 to 1650nm. If the customer requires an attenuator greater than 30dB, it can also be customized, but generally the delivery time will be longer than 0~30dB. When Kehai established the jumper production base in 2005, it also established the optical fiber attenuator workshop, and has been providing affordable products for customers at home and abroad. At present, the attenuator production process of Kehai Company is very mature, which can fully meet customer needs in terms of test indicators and end face control.
