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 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...

Do you know why some optical transceivers are colorful? Today will share the information about these colorful SFP modules. The colorful SFP modules are called wavelength division multiplexing (WDM) SFP module. WDM SFP is divided into two types: ◆ CWDM SFP ◆ DWDM SFP Different colors represent different wavelengths, today we mainly introduce CWDM SFP. Waht is CWDM SFP? CWDM SFP is a kind of optical...

Optical connectors are common throughout the network and give us the power to add, drop, move and change the network. However, it is an undeniable fact that the end face pollution of optical connectors is a major cause of the failure of the network. Today we will introduce the fiber end surface inspection. About end face pollution Like picture 1, the end face of the optical fiber or connector shal...
