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 optical… 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. And he has another questions, so we would like share at here. 1.How to connect the 2 transceivers in 2 switches with a patch cord directly? So we provide him… Continue reading How To Connect The 2pcs 100G SR In 2 Juniper QFX5110-32Q With A MPO Patch Cord Directly?
