CWDM multiplexer, the low price and high performance solution

CWDM multiplexer, the low price and high performance solution. The multiplexing technology refers to the process which integrates multi-channel in the transmission path and then restores the original mechanism or cancels the multiplexing technology in each channel of the terminal.


The multiplexing technology can be divided into the Frequency Division Multiplexing (FDM), Time Division Multiplexing (TDM), Code Division Multiplexing (CDM), Wavelength Division Multiplexing (WDM), Coarse Wavelength Division Multiplexing (CWDM) and the Dense Wavelength Division Multiplexing (DWDM).


The WDM means to transmit multi-channel optical signals with different wavelength in one fiber simultaneously. The WDM is used in the fiber channel.


The CWDM is the expansion of WDM. Each fiber will transmit 4 to 8 wavelengths. It is used in the medium size network system. The DWDM is also the expansion of WDM. The typical DWDM system supports more than 8 kinds of wavelength.


The display system will support hundreds of wavelength. The CWDM multiplexer save the fiber resources and the network costs effectively. It solves two problems that the shortage of the fiber and the multi-business transparent transmission.


The CWDM multiplexer is a transmission solution with low-price, low-power, and high-performance and it has been widely used in the metropolitan area network transmission and the FTTH.

How to choose and buy the built-in wireless network card for laptop . The WLAN is the abbreviation of wireless local area network. It uses wireless technology to transmit data signals, voice signals and video signals in the air. It is a new solution to mainly solve the problem of small range of wiring.   Simply, it realizes the wireless transmission from the broadband access devices, such as ASDL, LAN to our computers. Compared with the well-known CDMA and GPRS, WLAN is a completely different means to access Internet.   CDMA and GPRS belong to WLAN. They are equal to mobile Internet which need the help of the mobile communications network and it is billed according to the flow.

Which type of the wireless network card do I need

Which type of the wireless network card do I need . At present, the popular interface of wireless network cards include USB, PCI, EXPRESS CARD, Mini PCI and Mini pcie.   USB is the most common interface. It can be used on almost all of machines currently. It supports the hot-plug and it is convenient to use temporarily. But some network cards of USB have a higher requirement to the power supply. The motherland with lacking power supply may not be able to use these USB.   PCI network card is mainly used on desktops without too many compatibility problems. And it is very simply to install. PCI network card belongs to the built-in card so that the signal is easily affected by the

When can I get the fibre broadband

When can I get the fibre broadband ? The fibre broadband refers to the conversion of the electrical signal and the optical signal. To be exact, it converts the electrical signal into the optical signal for fiber optical communication.   The fiber is a most ideal transmission medium in the broadband network. It is characterized by the large transmission capacity, good transmission quality, low loss and the long-distance relay.   The fiber optical transmission uses the WDM to modulate the multiple users' date into optical signal with the different wavelength in the community. Then the optical signal will be transmitted in one fiber.   Sopto provides the comprehensive fibre
