Difference Between Single Mode and Multimode Fiber
October 30, 2023
Optical fiber attenuator is an optical device that can reduce the energy of optical signal. It is used to attenuate the input optical power and avoid the damage of receiving equipment caused by too strong input optical power
According to the shape, the Fiber Optic Attenuator can be divided into flange types (Picture 2) and male and female head type (Picture 3, 4, 5)
According to the function, the Fiber Optic Attenuator can be divided into adjustable (adjustable 6,7)and non-adjustable (other picture)
1).Low back reflection and Low PDL
2).High precision attenuation value
3).Precision control of attenuation range
4).Wide attenuation range
5).Precision ceramic ferrule
6).FC, SC, ST, LC … optional
7).Plastic or metal housing material
1).Fiber optical telecommunication system
2).Fiber optical CATV
3).Fiber optical sensor
4).Testing equipment
