MA905 is a common type of fiber optic connector, and its full name is SubMiniature version A 905. This connector usually adopts a threaded design and can be connected to other fiber optic devices by rotating the nut. It has the characteristics of stable connection, convenient operation, good durability, and strong resistance to environmental interference. Its ferrule is generally made of ceramic or metal, and can be connected to a variety of fiber types to adapt to different application scenarios.
Performance characteristics
1. Low insertion loss:
The insertion loss of SMA905 optical fiber plastic fiber jumper can usually be controlled within ≤0.5dB, which means that the intensity of the optical signal is less attenuated when passing through the jumper connection point, which can ensure a higher optical signal transmission efficiency and enable the receiving end to receive a signal of sufficient intensity, thereby ensuring the quality and stability of the signal.
2. High return loss:
With a return loss of ≥50dB, this feature effectively reduces the reflection of the optical signal at the connection point. High return loss can reduce the impact of reflected light on system performance, avoid mutual interference between reflected light and incident light, and improve the quality of optical signal transmission, especially in high-speed, long-distance optical communication systems, this performance is particularly important.
3. Good interchangeability and repeatability:
The connector of the jumper can still maintain stable performance after multiple plugging and unplugging, and the consistency and reliability of each connection are high. This makes it easy to plug and unplug the jumper when the equipment is maintained, upgraded or replaced, without causing the connection performance to deteriorate due to frequent plugging and unplugging, reducing the probability of system failure caused by connection problems.
Application scenarios
1. Short-distance communication:
Due to the relatively large transmission loss of plastic optical fiber, SMA905 fiber plastic optical fiber jumper is mainly suitable for short-distance optical signal transmission.
2. Industrial field:
In industrial automation control systems, it can be used as a link to connect sensors, actuators, controllers and other equipment to achieve high-speed data transmission and communication between equipment, ensuring precise control and efficient operation of industrial production processes.
3. Medical equipment:
It has important applications in some equipment in the medical field, such as laser surgical equipment, used to transmit high-energy laser signals to achieve precise surgical operations; in medical imaging equipment such as optical microscopes and spectrometers, it is used to transmit optical signals to help doctors obtain clear images and accurate detection data.
4. Test and measurement:
It is often used in instruments and equipment such as spectrometer testing and optical fiber testing as a jumper to connect optical fibers and instruments to facilitate the transmission and measurement of optical signals.
