With the explosive growth in AI computing power demand, ultra- high- speed optical modules such as 800G and 1.6T have become core equipment for data center interconnection and cloud network construction. LAN- WDM DFB fiber- coupled lasers, as the core light source at the module's transmitter end, are perfectly compatible with high-speed optical modules such as 800G/1.6T/400G due to their multi- wavelength characteristics and high linearity.
LAN-WDM DFB fiber- coupled lasers, with their multi- wavelength advantages and stable performance, support high- speed connections between ToR switches and servers within data centers (2- 10km), while also meeting the needs of data center interconnect (DCI) and next- generation co-packaged optics (CPO) and silicon photonics engine integration.
In the R&D, production, and testing of optical communication devices and modules, LAN- WDM DFB fiber-coupled lasers serve as a standard stable light source, widely used for performance verification of WDM devices (wavelength division multiplexers, optical amplifiers, etc.), and for eye diagram, bit error rate (BER), and sensitivity testing of 800G/1.6T optical modules, effectively accelerating product development and mass production.
LAN- WDM DFB fiber- coupled lasers, as O- band narrow-linewidth seed sources, can be applied to specific O- band distributed fiber optic sensing systems or short- range coherent sensing scenarios. Simultaneously, after amplification and modulation, they can also be used as a test light source for some short- range LiDAR applications, meeting the high- precision requirements of special scenarios such as industrial inspection and short- range ranging.
