DWDM is a dense wavelength division multiplexing technology that can multiplex multiple optical carriers into one optical fiber for transmission. Its product application scenarios are rich, mainly backbone networks, metropolitan area networks, data center interconnection, and cable television networks.   Backbone network – Long-distance transmission: used for inter-provincial and inter-city communication backbone lines, such as… Continue reading Application scenarios of DWDM products

We take mobile phones and computers every day, and we can smoothly browse Weibo, watch videos, and chat. These daily simple activities require a large-capacity transportation system to support them. Otherwise, Weibo, video, and WeChat information cannot be accurately delivered to your mobile phone or computer display. In this large-capacity transportation system, a technology that… Continue reading Network large capacity transmission technology – WDM/OTN

Compare DWDM and traditional optical technologies. DWDM saves fiber, boosts capacity, reduces costs, and enables quick service deployment.

Discover how DSP in coherent DWDM systems replaces traditional DCMs, offering cost-effective, flexible, and high-performance solutions.

You notice signal distortion due to nonlinear effects like Self-Phase Modulation (SPM) in a DWDM link. What’s the best initial approach to mitigate this effect?   1-Reduce input power to the fiber, this is the best way. Reducing the input power is the most effective first step to mitigate Self-Phase Modulation (SPM). SPM is a… Continue reading What’s the best way to mitigate signal distortion in DWDM link？

Fix low input power in DWDM networks. HTF offers 100G/200G/400G solutions for reliable, long-distance transmission.

One key factor that directly impacts the reliability to the DWDM paths is the power budget.   But what is Power Budget? The power budget in optical networking refers to the difference between the output power of the transmitter and the minimum input power required by the receiver. It accounts for all losses that the… Continue reading Why Power Budget is Crucial for DWDM Deployment?
