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...

Optical media converter is a medium for converting short distance electrical signals and long distance optical signals. According to the fiber type, the transmitting distance of media converter is different, so there are single mode media converter and multimode media converter. Today we will learn about the difference between single-mode fiber and multimode fiber. Structural differences between s...

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...

The are single and dual fiber optical transceiver. How do we choose, and what are their differences and advantages? Let’s learn about this! Single fiber module also called WDM module. It uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. BIDI module only has 1 port, wave filtering through the filter of module, and finished the transmitting of 131...
