аттенюатор мужского и женского типа
Introduce
Male to female fiber optic attenuators are doped fiber attenuators, providing low wavelength sensitivity, high stability, high return loss and good reliability. This makes our attenuators well suited for EDFA, DWDM and other high-power output applications, it's also called Plug-Type attenuator.
Features
Metal ion doped fiber
Attenuation levels ranging from 1dB to 30dB
Low back reflection
High power endurance
Maximum stability, reliability and flat spectral response
100% IL, RL and visual inspection tested
Easy to connect/disconnect (Push-Pull)
High mechanical resistance
Applications
Multiwavelength systems balancing
Passive optical networks
Optical power receivers protection
Fiber optical sensor
EDFA loop tests and measurements
