What is Dense Wavelength Division Multiplexing
Mar 08 , 2022
The so-called dense is relative to the interval between two adjacent wavelengths. In the past, the wavelength interval of the wavelength division multiplexing system was several tens of nanometers. Now the wavelength interval is only 02 to 1.2 nm. The spectrum allocation is shown in Figure 2-1. DWDM technology is actually a specific form of wavelength division multiplexing. Generally, the waveleng...

What is a fiber optic transceiver? What is the function of fiber optic transceiver?
Mar 25 , 2022
What is a fiber optic transceiver? Optical fiber transceiver is an Ethernet transmission media conversion unit that interchanges short-distance twisted-pair electrical signals and long-distance optical signals. It is also called a fiber converter in many places. The product is generally used in the actual network environment where the Ethernet cable cannot be covered and the transmission distance ...

FiberWDM compatible SFP/SFP+/QSFP Transceiver Modules
Apr 14 , 2022
Compatible optical transceiver modules are used to add fiber optic capabilities when connected to switches and use DDM/DOM (Digital Diagnostics/Optical Monitoring) technology to enable end users to monitor real-time parameters of the transceivers. Based on these monitoring parameters, network technicians can check and ensure that the modules are functioning well, including: Predict module life Loc...

What is a CWDM/DWDM multiplexer/demultiplexer?
May 20 , 2022
As we all know, WDM (Wavelength Division Multiplexing) is a technology that uses multiple lasers to send multiple lasers of different wavelengths on a single fiber at the same time. It can realize two-way communication on one fiber and increase network capacity. In a WDM system, a multiplexer is generally used at the transmitting end to multiplex several optical signals into a bundle of optical ca...

Introduction of 100G DWDM QSFP28 CS Connector PAM4 Transceiver
Jun 09 , 2022
What is PAM4? PAM4 is a technology that uses four different signal levels for signal transmission, and each symbol period represents 2 bits of logical information (0, 1, 2, 3). By transmitting two bits in one symbol slot, PAM4 cuts the signal bandwidth in half. With half the bandwidth, PAM4 can achieve 50Gb/s data transfer in a 25Gb/s electrical tolerance environment. Additionally, PAM4 minimizes ...
