General fiber to serial port 232/485/422 protocol format. Commonly known as three-in-one fiber serial converter, there is only one of the conversion of one of the functions, this depends on the specific needs of customers. So sometimes called a modem fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals with long-distance optical signals. It is also called optoelectronics in many places. Converter (FiberConverter).
Optical-to-electrical converters convert Ethernet electrical signals into optical signals for transmission, but they are not simply physical conversions. There will be corresponding protocol conversions. Sometimes the market is also called a fiber switch. However, it is different from industrial Ethernet switches. Their level lines and hardware are not the same. Industrial Ethernet switches have storage hard disks and have different Ethernet switches at the levels of 100M, 10G, and 10G. Can form a large ring network switch to use. The use of the environment is also relatively complicated.
The optical transceiver is a fiber-optic communication device that extends the data transmission. It mainly uses signal modulation, photoelectric conversion and other technologies to utilize optical transmission characteristics to achieve long-distance transmission.
Optical transceivers are generally used in pairs and are divided into optical transmitters and optical receivers. The optical transmitters perform electrical/optical conversion and transmit the optical signals for optical fiber transmission. The optical receiver mainly restores the optical signals received from optical fibers to Electrical signals complete the light/electrical conversion. The role of the optical transceiver is to transmit data remotely.
The optical fiber interface has SC/FC\ST type, with single mode dual fiber and single mode single fiber.
Fiber optic transceivers have the same division. Their transmission distance is 20KM, 40KM, 80KM, 120KM.
This new generation overlock is a combination of precision machinery and electronic technology.It is widely used for the joint seaming and decoration seaming on various materials,such as general garments/underwear/bedclothes/thick package/leather products,there are many different stitches for your selection.The thread tension is easy to adjust to achieve better sewing quality.The highest speed is up to 7000rpm.It greatly enhances the production efficiency.The needle bar inbuilt is to prevent oil leakage,meanwhile the components are especially designed for antifriction,more wearable and enduring,save the maintenance,save your cost.
