Related working principle and applications of Tunable DWDM transceiver
Sep 07 , 2021
DWDM is a laser technology used to increase bandwidth on existing fiber optic backbone networks. More precisely, the technology is to multiplex the tight spectral spacing of a single fiber carrier in a specified optical fiber in order to utilize the achievable transmission performance (for example, to achieve the minimum degree of dispersion or attenuation). In this way, With a given information t...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Sep 26 , 2021
What are the performance indicators that affect the WDM wavelength division multiplexer? 1. Working band The working band of WDM devices, such as 1550 wavelength, is divided into three bands: S band (short wavelength band 1460～1528nm), C band (conventional band 1530～1565nm), L band (long wavelength band 1565～1625nm). 2. Number of channels and channel spacing The number of channels refers to the nu...

Why Choose a 40-Channel DWDM Multiplexer/Multiplexer
Mar 04 , 2022
DWDM (Dense Wavelength Division Multiplexing) is an ideal optical multiplexing technology for long-distance data transmission, which can put multiple channel information using a single wavelength on the same fiber and greatly improve the transmission capacity of optical networks. At present, DWDM technology is widely used in telecommunication networks and has become the choice of many telecommunic...

Working principle and features of 40G QSFP+ BIDI transceiver
May 10 , 2022
A BIDI transceiver is called a bidirectional transceiver, it operates on two different wavelengths and transmits in both directions over only one fiber. To distinguish, BIDI transceivers have only one connection port, while ordinary optical transceivers have two ports. Why can signals with different center wavelengths be sent and received bidirectionally in a BIDI transceiver? It is very important...
