Mpls-multi-protocol Label Switching

Multiprotocol Label Switching (MPLS) is a new IP backbone network technology. MPLS introduces the connection-oriented label switching concept on connectionless IP networks, and combines Layer-3 routing technology with Layer-2 switching technology, giving full play to the flexibility of IP routing...

Briefly introduce about WiFi antenna

Antenna is a passive device, which mainly affects OTA power, sensitivity, coverage range and distance, while OTA is an important means to analyze and solve the throughput problem. Usually, we mainly measure the antenna according to the following parameters (the performance will also affect the th... Read More

OLT and ONU

Optical access network (that is, the access network with light as the transmission medium, instead of copper wire, is used to access each family. Optical access network).Optical access network generally consists of three parts: optical line terminal OLT, optical network unit ONU, optical distribu... Read More

What is the ONU (Optical Network Unit) and what are the specifications?

What is ONU? Today, ONU is actually very common in our lives. The network connection provided by the operator installed in everyone’s home is called Optical Modem, also known as ONU device. The network of the operator is connected to the optical device, and then connected to the PON port of... Read More

How to choose an optical module?

When we choose an optical module, in addition to the basic packaging, transmission distance, and transmission rate, we should also pay attention to the following factors: 1. Fiber type Fiber types can be divided into single-mode and multi-mode. The center wavelengths of single-mode optical modu... Read More

The structural composition and key technical parameters of the optical module

1. The average transmitted optical power refers to the arithmetic mean of the optical power when the signal logic is 1 and the optical power when it is 0. 2. The extinction ratio refers to the ratio of the average transmitted optical power of all “1″ codes to the average transmitted ... Read More
