Product Description

SC/APC Male to Female Singlemode Fiber Optic Attenuator, Build-out Type


Hangalaxy’s Single-Mode Fixed Fiber Optic Attenuators offer low return loss, high mode stability and a variety of attenuation values: 3, 5, 10, 15 and 20dB. As optical passive devices, FS attenuators are 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.


Keyed Characteristics

(1) Adaptor Type Attenuator is optimized for operation at either 1310nm and has a bandwidth of ±40nm. This compact attenuator have a male FC/PC connector at one end and a female FC/PC connector at the other end, enabling it to be placed in the optical path without additional fiber pigtails and connectors. The 3dB attenuation is accurate to <±1.0dB;
(2) Designed to provide flat spectral attenuation required to function in all the wavelengths.

(3) Hangalaxy male-to-female attenuators contain doped fiber suitable for both 1310nm and 1550nm operation. Build-out attenuation values are available in 1dB increments from 1 to 20dB. FIS stocks standard 5, 10, 15, 20dB attenuation levels in most styles.



(1) Telecommunication Networks;
(2) CATV Networks;
(3) Data Communications;
(4) Local Area Networks.

The most common version of attenuators are, as shown below, male to female units, often called plug-style or buildout style. These plug-style attenuators simply mount on one end of a fiber optic cable, allowing that cable to be plugged into the receiving equipment or panel. We also have female to female (bulkhead) attenuators, often used to mount in patch panels or for connecting two fiber optic cables together. More expensive, but useful for testing, are variable attenuators which are adjustable between 1dB and 30dB. We also can custom build in-line attenuators where the attenuator is incorporated within a fiber optic patch cable, built to your specifications.

The dB ratings are a measure of signal strength and can sometimes be confusing. The chart below will give you an idea of the percent of attenuation of your signal for specific dB values. Attenuation % (signal reduction) for different dB values
1dB = 21% / 6dB = 75%
2dB = 37% / 7dB = 80%
3dB = 50% / 10dB = 90%
4dB = 60% / 13dB = 95%
5dB = 68% / 15dB = 96.8%
