Last week, some customers asked me some information about the 40G QSFP+ & 4*10G SFP+. So in order to know more better about the products, we now share the working principles with you, hope it can be helpful for you and your business. Totally, for the wavelength of 40G QSFP+, the 4 channels are different ---- 1270/1290/1310/1330nm. 1. 40G QSFP+ to connect 40G QSFP+: When you connect the QSFP+ t...

In 10G networks, engineers are often confused about the choice of optical fiber or copper / optical cable. Today, ETU-Link will analyze three 10G network communication solutions for everyone to reference. Solution 1: 10G SFP+ module + patch cord + 10G SFP+ module Solution 2: 10G SFP+ to 10G SFP+ DAC Cable In the data center, copper cable is usually used in connecting the server and storage area ne...

With the company’s steady development, engineers are working hard and continuous R & D high-speed optical module. ETU-Link officially released a new generation of 10G 1310nm ER optical transceiver —— ESP3192-3LCD40, SM 40KM. Compare with SFP+ 1550nm 40km, 1310nm 40KM is more competitive. Advantages: 1.40KM fiber testing: The Engineers tested the modules via Corning 40km fiber testing to ensure...

BIDI SFP is a bidirectional optical 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 1310nm optical signal and receiving of 1550nm optical signal, or opposite. Therefore the module must be used in pairs. ...

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...
