Description
● Description:
Fiber optic attenuators are devices which reduce (attenuate) the strength of a fiber optic signal within a fiber optic network. Attenuators are usually used when the signal arriving at the receiver is too strong and hence may overpower the receiving elements. This may occur because of a mismatch between the transmitters/receivers (transceivers, media converters), or because the media converters are designed for a much longer distance than for which they are being used. Sometimes attenuators are also used for stress testing a network link by incrementally reducing the signal strength (increasing the dB attenuation) until the optical link fails, thus determining the signal’s existing safety margin.
Plug-in fixed optical attenuator provides a connector plug (male) and an adapter socket (female) to connect between fiber patch cord and fiber adapter. In-line attenuator resembles a patch cord and is typically used between the patch panel and the receiver. Bulkhead female to female attenuator is ideal for use in fiber optic patch panels, instrument front panels and other applications that require a fixed level of attenuation and easy connectivity. Variable attenuator is used in optical fiber transmission lines, continuous variable attenuation of light intensity, to reduce the product accessories, low loss, high precision adjustment, widely used in optical communication systems for various measurement systems.
Pancomlink’s 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. 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.
