Due to the development of microelectronic technology, active and passive optical devices technology, optical transceiver has become the mainstream of the common optical module in recent years. Although the optical module package, rate, transmission distance is different, but its internal composition is basically the same. Today we will learn and explore the working principle of the optical transce...

The optical transceiver is composed of optoelectronic devices (TOSA, ROSA, BOSA), functional circuit (PCBA) and optical interface. Its function is to achieve photoelectric conversion. The transmitting end converts electrical signals into optical signals, and the receiving end converts the optical signal into electrical signal through the optical fiber transmission. ETU-Link sincerely recommend you...

Optical attenuator is the optical device for reducing optical signal power. Depending on the application, the optical attenuator can be divided into adjustable optical attenuator and fixed optical attenuator. Today we will introduce the basics of fixed optical attenuators. The attenuation power of fixed optical attenuator is fixed(1 dB, 5 dB, 10 dB etc). The attenuation power of fixed optical atte...

Looking at the dim lights in front of the door, vaguely shining scanty passers-by, the front of the seat has been all empty. There may be some loneliness and loneliness on the way to success, always have ups and downs some people didn’t experienced.   16 years has become a history, what did I gain? Medals? Bonus? Perhaps this is a node of life. In fact, the biggest feeling is to use...
