FC UPC Singlemode Fixed Fiber Optic Attenuator, Male-Female

Fiber Optic Cable Single-mode Attenuator FC/UPC:

FC fiber optic attenuator includes FC single mode female to male and female to female fiber optic attenuator from 1dB to 30dB.to connect FC fiber optic pigtail or patch cables to reduce the power of signal at a certain attenuation. FC fiber optic attenuator features high power endurance and low back reflection. FC Fiber Optic Attenuators are used in communication systems to reduce optical power launched onto the photo detector. These high performance devices are designed to give accurate attenuation over a wide range of wavelengths. The plug type configuration allows them to be used directly on the end of a patch cord, which in turn can insert directly into an adaptor. FC Fiber Optic Attenuators is one kind of optical passive device which is used to debug the performance of the optical power in the optical communication system,debugging fiber optic instrument calibration correction, optical signal attenuation. And used for the attenuation of the input optical power, avoid optical receiver distortion due to input optical power powerful. Applications of the FC fiber optic attenuators include CATV networks, data communication and telecommunication networks. Fiber Optic attenuators are able to control the output of the fiber light power level.Fiber optic attenuator are used for reducing the power of the light in the fiber optic network

  1.This attenuation does not include insertion loss. This value is measured by using a detector in free space, so if it is used as an intermediate element between two fiber coupling components,             additional losses can be expected.

  2.The shaded portion of these curves represents the operating wavelength range we specify for each attenuator. Performance beyond this range is not guaranteed.

When to Use Fiber Optic Attenuators?

Considering when to use fiber optic attenuators in your system, there are generally two different situations where you will need fiber optic attenuators.

• One is when fiber optic attenuators are used to reduce the receiver power. There are sometimes when signal arriving at the receiver is too strong and may overpower the receiving elements. Usually, the receiver power depends on two factors: how much power is launched into the fiber and how much power is lost by the attenuator. Too much receiver power can be mainly caused by the mismatch between the transmitters/receivers, or caused by the use of media converters designed for a much longer distance. In this case, optical attenuators can be permanently installed in the fiber optic link to reduce the signal power and properly match the signal level.

• The other one is when the attenuators are used for testing the power level margins. When testing the optic power level, the attenuators are used to temporarily add a calibrated amount of signal loss to test the power level margins in the fiber optic system. With the transmitter turned on and using a fiber optic power meter which is set to the system operating wavelength, the attenuator can be used to test the system power.

How to Use Fiber Optic Attenuators in Data Link?

For single-mode applications, especially analog CATV systems, the most important parameter second to the correct loss value is return loss or reflectance. Many types of optical attenuators (especially gap loss types) have the common problem of high reflectance, so they can adversely affect transmitters just like highly reflective connectors.

Considering how to use optical attenuators in link data, first, you need to choose an attenuator with good reflectance specifications. And second, always install the attenuator at the receiver end of the link as shown above. This is because it's more convenient to test the receiver power before and after attenuation or while adjusting it with your power meter at the receiver, plus any reflectance will be attenuated on its path back to the source.

When testing the system power, you need to make sure the transmitter is turned on and the optical attenuator is installed at the receiver. Don't forget to use an optical power meter which is set to the system operating wavelength. And next, check to see whether the power is within the specified range for the receiver. If the optical power is higher or lower than the configuration required, the optical attenuators should be changed to adjust the power again.
