 SC Fiber Optic Attenuator or SC APC Fiber Optic Attenuator

We supply single mode SC fiber optic attenuators, they are available by bulk headed type or plug female to male type. The SC fiber optic attenuators work in the 1250nm to 1625nm range, with attenuation range from 1dB to 30dB optional.

 

LC Fiber Optic Attenuator
We supply LC fiber optic attenuators; these products are used in the fiber optic links to reduce the optical power at a certain fixed rate. LC fiber optic attenuators work in 1250-1625nm range with optional attenuation value from 1dB to 30dB.

ST Fiber Optic Attenuator
ST fiber optic attenuators are used to connect two ST fiber connectors, during the connection; the ST fiber attenuator will weaken the optical signal at a certain fixed value. These products are used in overpowered fiber systems where people need to lower the optical signal strength level.

 FC Fiber Optic Attenuator
We supply FC fiber optic attenuators; these products are used in single mode applications at 1250 to 1625nm wavelength range. We supply FC fiber optic attenuators from 1dB to 30dB.

 Inline Fixed Value Fiber Optic Attenuator
We supply single mode inline fiber optic attenuator and multimode inline fiber optic attenuator. These products are with optional connectors including SC, ST, FC, LC, MU, E2000, etc, the cable length can be custom made. These inline fixed value fiber optic attenuators working range is typical 1260 to 1620nm for single mode and 850/1300nm for multimode.

 

 

 

 

 

 

 

 

 

Fiber Optic Attenuator Manufacturer and Distributor. 

Fiber optic attenuators are used in the fiber optic links to reduce the optical power at a certain level. We supply various kinds of fiber attenuators, including LC, SC, and ST, FC, MU, E2000 and Variable fiber optic attenuators.

Commonly used fiber optic attenuators are the female to male type, which is also called a plug fiber attenuator. They are with ceramic ferrules and there are various types to fit different kinds of fiber optic connectors. Fixed value fiber optic attenuators can reduce the optical light power at a fixed level, for example, a 10dB SC fiber optic attenuator will reduce the optical power 10dB and utilize a SC male to female attenuator.  Variable fiber optic attenuators are with adjustable attenuation range. There are also attenuation fiber optic patch cables available, their function is same as attenuators and are used inline.

Our fiber optic attenuators are manufactured according to industrial standards, and they are 100% strictly tested during the production. These fiber optic attenuators are prompt delivery and good prices.

An optical attenuator uses a segment of attenuating fiber interposed in the optical path. The attenuating fiber is produced by using a solution doping technique to introduce transition or rare earth elements into the fiber's core. The dopant reduces the transmission of the fiber. The degree of attenuation depends upon the material used as the dopant, the dopant level, and the length of the attenuation segment. In a specific embodiment, an optical attenuator is provided having a first and second signal carrying optical fibers and an attenuating fiber segment, each of which has a core, a cladding substantially coaxial with the core, and a substantially planar end face. The attenuating fiber segment is fusion spliced between the first and second signal carrying optical fibers. In a second embodiment a portion of the cladding of the attenuating fiber is chemically etched.
