Skip to content Fiber attenuator is a passive optical device used to reduce the power of an optical signal. It adjusts the input optical power to the desired level by absorbing or reflecting excess light energy. Its main function is to prevent distortion in the optical receiver due to excessive signal strength, and it is used for debugging, testing, and power balancing in optical communication systems.
Yingda provide a variety of high-precision, highly stable fiber attenuators. All optical attenuators adopt imported attenuating fibers, and rigorously tested and qualified before shipment.
Based on the attenuation method, it can be classified into fixed and adjustable types, the key difference are whether the attenuation level is adjustable or not.
Fixed attenuators include female-to-female attenuators and male-to-female attenuators. Variable attenuators include two types: MEMS VOA attenuators and in line varialbe attenuators.
The fiber optic attenuators provided by Yingda offer stable performance and extremely high attenuation accuracy. All test data is included with the shipment packaging sent to the customer. The power handling capacity is typically 500mW, and the attenuation accuracy is generally ±0.05dB for fixed attenuators and ±0.2dB for adjustable attenuators.
✅ 400G interconnection in data centers: transmission distance ≤100m, power consumption <4W, bit error rate <10⁻¹², QSFP-DD AOC cable is recommended, which saves 50% energy consumption compared to DAC.
We have a large stock of commonly used attenuators, ensuring fast delivery.
Commonly used attenuators include LC APC attenuators, LC UPC attenuators, SC attenuators, and SC APC attenuators.
As long as there is enough space on the fiber attenuator, we can laser print the customer's logo. The final decision will depend on the specific model.
The price of fiber optic attenuators varies significantly depending on the packaging type. The cheapest are male-to-female attenuators, which are the most commonly used, and their price is approximately USD 0.8-1.0. Variable attenuators or desktop attenuators are much more expensive. Please contact our sales team for more details.
The typical lifespan of a fiber optic attenuator is 50,000 hours (approximately 5 years), which is a theoretical value based on continuous 7x24 hour operation according to international standards. The actual lifespan may vary depending on the working environment, frequency of use, and manufacturing process.
There are mainly 4 type: Fixed type, male-female type, mechanically adjustable type, in-line type, etc.
The main parameters of a fiber optic attenuator include attenuation range, operating wavelength, insertion loss, power handling capacity, attenuation accuracy, fiber type and packaging, and fiber connector type.
High productivity efficiency, skilled front-line operators and strict production control ensure timely delivery.
High-precision testing equipment and top industry quality control system ensure high quality standards.
Long-term stable supply chain and cost control that changes in line with market trends ensure the best price
