1. What is a CDN The full name of CDN is Content Delivery Network, that is, content distribution network. Its purpose is to add a new layer of CACHE (caching) layer to the existing Internet, and publish the content of the website to the node closest to the user‘s network “edge”, so that users can… Continue reading One article helps you clearly know what is CDN

In the early years of the enterprise, the IP network segment was configured as a large segment, but now it does not want to change the IP network segment but wants to divide VLANs, what should I do? This kind of problem needs super vlan to help! The concept of Super VLAN Super VLAN (Super… Continue reading Super VLAN-Super VLAN technology

  ROADM can implement multi-degree large-capacity wavelength-level scheduling to meet the networking demands of backbone, metro and data center interconnection (DCI). However, as the degrees of a ROADM grow, the number of fiber connections inside the ROADM site increases dramatically, which makes the service provisioning and maintenance process time-consuming, prone to human errors and increases… Continue reading OXC vs ROADM

Layer 3 switching technology = Layer 2 switching + Layer 3 routing working principle When the data is received by the port chip, the corresponding destination MAC address is first searched in the Layer 2 switching chip. If found, the Layer 2 forwarding is performed, otherwise the data is forwarded Sent to the Tier 3… Continue reading Working principle of layer 3 switch

Optical Active Devices Categories Introduction In fiber optic networks, optical active devices are key components. It can convert electrical signals and optical signals to each other, the optical transmission system of the heart. Optical active devices are divided into the following three categories.   A. Light Source   The device that converts electrical signal into… Continue reading Optical Active Devices Categories Introduction

100G ultra-long-distance transmission optical module is coming, 2000km transmission is not a dream!!! The transmission distance of an optical module is a core parameter. In view of the market demand and network trend of ultra-long-distance transmission, ultra-long-distance transmission solutions have become the development trend of the future communication industry. In the actual use of ultra-long-distance… Continue reading 100G ultra-long-distance transmission optical module is coming, 2000km transmission is not a dream!!!

When designing a DWDM optical transmission solution, the distance between the two places is too far, and if a relay is added in the middle, it will cost a lot of money, or the middle is next to the desert, and a relay station cannot be set up. How to ensure the stable transmission of… Continue reading How to realize the ultra-long distance non-relay transmission of optical signals

Last time one of our customers bought 100G SR4 MPO 100M, They feedbacked compatible with Juniper QFX5110 Switch, and will order more from us in 2020.
