SC / APC Fiber Optic Attenuator 5dB 10dB 15dB ROHS Certification
♦ Details
Fiber Optic Attenuator is a component installed in a fiber optic transmission system that reduces the power in the optical signal. It is often used to limit the optical power received by the photodetector to within the limits of the optical receiver.
Optic fixed type adapter (female to female) attenuator can be selected in need of the project. It is used in the fiber transmission system.
As a optical passive devices, Otop attenuators mainly used in fiber optic to debug optical power performance & optical instrument calibration correction & 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.
These fiber optic attenuators consist of a male LCA connector on one end and a female LCA connector on the other end. When a cable end in inserted into the female end, the remaining male end can be connected to the equipment where the cable would otherwise connect directly, but providing the desired signal strength reduction.
All Otop attenuators are built with the highest quality materials and factory tested to ensure precise attenuation and performance.
