FC/UPC Fiber optic Attenuator, Male to Female, 1~25dB

FC/UPC Fiber optic Attenuator, Male to Female, 1-25dB

FC/UPC Fiber optic Attenuator, Male to Female, 1-25dB , or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable.

The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc. Optical attenuators usually work by absorbing the light, like sunglasses absorb extra light energy. They typically have a working wavelength range in which they absorb all light energy equally. They should not reflect the light or scatter the light in an air gap, since that could cause unwanted back reflection in the fiber system. Another type of attenuator utilizes a length of high-loss optical fiber, that operates upon its input optical signal power level in such a way that its output signal power level is less than the input level

Fiber Optic Attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself. The basic types of optical attenuators are fixed and variable, and are designed to be used with various kinds of fiber optic connectors. The attenuators can be female to female or male to female.

FC UPC single mode fiber optic attenuator and FC UPC single mode fiber optic attenuator are available, both of them are with ceramic sleeves and accurate FC connection interface. The attenuation range is from 1dB to 30dB available. The FC fiber attenuator features high power endurance and low back reflection. They are used to reduce the optical power in the fiber optic links.

Product Specification

high quality build-out attenuators ranging from 1 to 30dB. Each attenuator is made with continuous light-absorbing and metal-ion doped fiber which offers excellent environmental stability and low back reflection. The front of the attenuator is a male plug connector style that allows the attenuators to be plugged directly into receiver equipment or adaptors in patch panel. The rear is a female socket adaptor that allows a patch cord to be mated into the back of the attenuator. The attenuator is available in SC, FC, ST, LC, and MU type. In a fiber optic system, build out attenuators play an important role in controlling optical power levels in Telecommunications, CATV applications and other single mode fiber optic communications applications. As such, they must offer consistent performance over a range of operating conditions so attenuation levels remain constant and predictable.

Specification

Highly Efficient, Stable and Durable

Good interchangeability, repeatability, thermal stability and abrasive resistance; High reliability and performance. Low insertion loss: average additional loss value lower than 0.2db；High return loss: more than 1000 times insertion and extraction.

Excellent Isolating Effect, Eliminating Damage Effectively

Noise caused by group loop can be effectively restrained. Electrically, signal field is entirely isolated from host control terminal,thus accidental damage to the host controller can be highly avoided.

High Optical Performance, Excellent Mechanical Stability

Advanced grinding machine enables fiber’s center grinding offset. We adopt zirconia ferrule with alkali resistance, acid resistance, high-temperature resistance and ultrahigh-hardness, which possess high optical performance and excellent mechanical stability.
