Fixed Plug in Attenuators(male to Female) are used in optical systems where the optical power from a source is too high for the test equipment in use. The fixed plug in attenuator introduces an in-line fixed loss that will reduce the source power to an acceptable detection level. The attenuation level should be stable with temperature and wavelength for a stable reliable system.
ADTEK produces a wide range of Plug-Type single mode attenuator. They are used directly on the fiber optic connectors and provide a fixed level of optical attenuation. They have low return loss and works at both 1310nm and 1550nm wavelength range. FC and SC connector types with PC or APC polish are available, as well as ST and LC types of attenuators.
Fixed bulkhead type attenuators (Adapter type) utilizes the air gap between two connectors to achieve the optical attenuation. This fixed optical attenuator has a similar structure of a standard female-female fiber adapter. It is simple, low-cost and compact.
They are recommended for use where return loss is not a concern nor is absolute attenuation value. The attenuators are available in ST/PC, FC/PC, or SC/PC format, with fixed attenuation values of 3dB, 5dB, 10dB, 15dB, and 20dB. Multimode or Singlemode fiber optic attenuators can be supplied for operation at 850nm, 1300nm, or 1550nm.
Fixed in line attenuators are used in optical systems where the optical power from a source is too high for the test equipment in use. The fixed optical fiber attenuator introduces an in-line fixed loss that will reduce the source power to an acceptable detection level. The attenuation level should be stable with temperature and wavelength for a stable reliable system
ADTEK produces a wide range of fixed in-line singlemode and multimode attenuator. They are used directly on the fiber optic connectors and provide a fixed level of optical attenuation. Single mode fiber based attenuators with single window (1310nm or 1550nm) or dual window (1310nm&1550nm). Multimode fiber based attenuators with single window (850nm or 1310nm). FC and SC connector types with PC or APC polish are available, as well as ST and LC types of attenuators
Fixed hybrid fiber attenuators allow users to convert from one connector type to another.
Fixed hybrid optical attenuator with male to female configuration are very useful in connecting patch cables with different connectors. Because both a connector plug (male) and an adapter socket (female) are provided, this hybrid adapter fits in various circumstances, offering flexibility and reducing the size, weight and complexity of the system.
ADTEK''s fixed hybrid attenuators are comprised of a polymer/metal outer body and inner assembly fitted with a precision alignment mechanism. The combination of a ceramic alignment sleeves and a precision moulded combination of a ceramic alignment sleeves and precision moulded polymer housing provides consistent long-term mechanical and optical performance. They have low insertion loss and high return loss.
We provide 1~20 dB and standard attenuation values at 3, 5, 10, 15 and 20 dB, advantaging economy scale for mass productive supply and custom-made attenuation value meeting your specific requirement , supported by our technical team to obtain the best synergy.Comply with Bellcore GR-910-CORE
Variable bulkhead type attenuator (adapter type,female to female) has a structure similar to an optical adapter. It utilizes the air gap between the two connectors to realize optical attenuation. However, the air gap can be continuously adjusted and fixed manually. This induces a variable optical attenuation from 0.5dB to 20dB. This component can be used in applications where optical attenuation needs to be frequently adjusted.
The Variable adapter type attenuator has included tool provides ability to increase attenuation level to desired dB. Their attenuation range is 0dB to 20dB depending on light source.
ADTEK provides a wide range of adapter type single mode and multimode variable attenuator. They have low return loss and works at both 1310nm and 1550nm wavelength range. ST and FC connector types with PC or APC polish are available.
Variable plug in attenuators(male - female) has a ceramic alignment sleeve that provides a low insertion loss of 0.15dB and can be used on both multimode and singlemode applications. This "air-gap control" variable attenuator is commonly used as a verification tool and for temporary adjustment of the attenuation value. Different attenuation value can be maintained.
The Variable plug in attenuator has included tool provides ability to increase attenuation level to desired dB. Their attenuation range is 0dB to 20dB depending on light source.
ADTEK supplies a wide range of plug-type single mode and multimode variable attenuator. They have low return loss and works at both 1310nm and 1550nm wavelength range. ST and FC connector types with PC or APC polish are available, as well as SC and LC types of attenuators.
Fiber Optic Attenuator
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 attenuator.
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 attenuator can reduce the optical light power at a fixed level, for example, a 2dB SC APC fiber optic 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.
Sometimes in the fiber optic network ,people may need to reduce or balance the power of the light transmitted from one device to another device ,fiber optic attenuators are used in such cases, they 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. we supply two types fiber optic attenuator, fixed value fiber optic attenuator refer to the attenuator that can reduce the power of fiber light at a fixed value loss, for example, 2dB. While adjustable fiber optic attenuator refer to the attenuator that can generate a adjustable Loss to the fiber optic link. our fiber attenuator series include:SC ,FC,LC,ST ,MU,SC/APC ,FC/APC,single mode fiber optic attenuator and multimode fiber optic attenuator available.Our fiber optic attenuators are manufactured according to international standard and are compartible with the fiber optic products currently available in the international market.
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.
