Optical attenuators are designed to introduce specific attenuation of the optical signal in a fiber optic line, allowing the signal to be reduced to the required level. By using specialized optical fiber in their design, fixed-level signal attenuation attenuators are often used where significant signal attenuation is needed with minimal return loss (up to -65 dB). The main characteristics of attenuators include: low return loss (RL), high stability of the set attenuation level, compact size, high mechanical strength, and a wide operating temperature range. Optical attenuators look similar to standard optical pass-through connectors (sockets, adapters) such as FC, SC, or other types. Attenuation is determined by a calibrated air gap. OPTOKON offers a wide range of optical attenuators with fixed attenuation levels of any nominal value from 1 to 30 dB, for both single-mode and multi-mode fibers, with any type of optical connector.
Connector-type optical attenuators are fully compatible with SC, FC, ST, and LC connectors. They are used to adjust the linear and dynamic range of power meters, as well as to regulate the power level of signals in electro-optical converters and optical communication networks at the output of light sources. Additionally, variable attenuators are used in optical amplifier systems to balance gain across different operating wavelength ranges. Attenuators are designed to introduce specific attenuation of the optical signal in a fiber optic line, allowing the signal to be reduced to the required level. They are used to prevent overloading of the receiver module of active equipment. Optical attenuators use several technologies to reduce the optical signal power level. The main characteristics of attenuators include: high stability of the set attenuation level, low return loss, wide operating temperature range, compact size, and high mechanical strength. All these characteristics allow their use in many applications, from local networks and cable television networks to control and measurement tasks. OPTOKON offers a variety of optical attenuators with adjustable attenuation levels, for single-mode and multi-mode fibers, with any type of connector.
Optical terminators are used as a "plug" for the optical line. Their main purpose is to protect maintenance personnel from accidental exposure to optical radiation in the eyes from an open optical port in the distribution panel, as well as to reduce unwanted optical signal reflection. Loopback attenuators with low optical signal reflection are used to optimize the performance of the optical network. The implementation of a special assembly process, as well as the latest manufacturing technology, which improves the thermal stability of insertion losses, allows us to create the most precise attenuators on the market. The main characteristics of loopback attenuators include a compact, reinforced housing that protects the fiber from damage, low insertion losses, and a wide attenuation range. Loopback attenuators are manufactured for both single-mode and multi-mode applications with connectors of all major types. Various color solutions make it easy to identify the connector polish type and wavelength.
