Customized LC Fixed Fiber Optic Attenuator, SM/MM, Male-Female, 1~25dB Optiona
Hanagalxy attenuators are a very high quality design using doped fiber to attenuate the signal. Our singlemode attenuators offer a operating wavelength range of 1250nm to 1600nm, covering both the common 1310nm and 1550nm operating wavelengths. The attenuation accuracy is +/- 0.5dB, up to 5dB and +/- 10% over 5dB. The return loss is >50dB for standard connectors and >60dB for APC connectors. Maximum transmission power is typically one watt. We stock attenuators for the following fiber optic connector types: ST, SC, SC/APC, FC, FC/APC, LC, LC/APC, MU. Other connector type attenuators are available upon special order. We stock most values between 1dB and 25dB for each of these attenuator types. Although fiber optic attenuators are normally used in singlemode circuits, because this is where the stronger lasers are used for distance transmission, we also have multimode attenuators available (upon special order) in 50/125 and 62.5/125 fiber sizes. Since these will be custom made, minimum order quantity (50+) and extended lead time (2-4 weeks) may be required.

Attenuator Application
Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high power applications.

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%
