Application Fields
* Optical Fiber Communication Systems: It is widely used in long - haul trunk lines, metropolitan area networks, local area networks, and other optical fiber communication networks. It realizes the multiplexing and demultiplexing of optical signals with different wavelengths, increases the transmission capacity of optical fibers, and improves the bandwidth and transmission performance of the network to meet the growing demand for communication data.
* Data Centers and Cloud Computing: In the interconnection within data centers and between data centers, it is used for high - speed data transmission and switching. It supports high - capacity data communication among multiple servers, improving the operational efficiency and performance of data centers.
* 5G Fronthaul Networks: In 5G communication systems, it is used in the fronthaul links between base stations and between base stations and the core network. It enables the transmission of multiple - wavelength optical signals in a single optical fiber, addressing the demand for fiber resources in 5G networks due to large - volume data transmission, and improving transmission efficiency and capacity.
12Ch O - band LWDM Mux/DEMUX is a device applied in optical communication systems, mainly used for the multiplexing and demultiplexing of 12 optical signals in the O - band. Here is a detailed introduction:
LAN-WDM(Local Area Network Wavelength Division Multiplexing) or LWDM is fairly new type of wavelength division multiplexing (xWDM) that utilizes multiple wavelengths with a spacing of approximately 800 GHz (4.26nm to 4.62nm). Its channel interval is 200~800GHz, this range is between DWDM (100GHz, 50GHz) and CWDM (about 3THz). The IEEE has defined 12 LWDM channels ranging from 1269.23nm to 1318.35nm. LWDM offers high reliability and stability,high channel isolation, and low insertion loss. Furthermore, LWDM can support 12-wave 25G to increase the capacity and save fiber.

Technical Features
* Wavelength Range and Spacing: Operating in the O - band, the wavelength range is generally around 1260nm - 1360nm. The wavelength spacing is relatively small and uniform, usually following an 800GHz grid (4.5nm). This enables the multiplexed transmission of multiple wavelengths within a limited band, improving spectral efficiency.
* Low Insertion Loss: The insertion loss is typically less than 2.0dB. A low insertion loss means that the optical signal experiences less energy loss during the multiplexing and demultiplexing processes. This ensures the transmission quality and intensity of the signal, reduces the attenuation of the optical signal, and is beneficial for long - distance transmission.
* High Channel Isolation: The adjacent channel isolation is greater than 30dB, and the non - adjacent channel isolation is greater than 40dB. High isolation effectively prevents interference between optical signals of different wavelengths, ensuring the integrity and independence of each channel's signal, and improving the reliability and stability of the system.
* Low Polarization - Dependent Loss (PDL): The PDL is less than 0.5dB, indicating that the device is insensitive to changes in the polarization state of the optical signal. Regardless of how the polarization direction of the optical signal changes, it can maintain relatively stable transmission performance, reducing the impact of the polarization state on signal transmission.
* Small Size and Compact Design: The module has a small size, such as 25x19.6x6.5mm, saving installation space. It is easy to integrate into various optical communication devices and systems, facilitating the miniaturization and high - density integration of optical communication systems.
