DDM (Digital Diagnostic Monitoring) is a technology used in optical modules. It is used to diagnose the working state of optical modules. It is a real-time parameter monitoring means of optical modules. It allows users to monitor the parameters of optical modules in real time, including received ...

WiFi products require us to manually measure and debug the WiFi power information of each product, so how much do you know about the parameters of WiFi calibration, let me introduce to you: 1. Transmitting power (TX Power): refers to the working power of the transmitting antenna of the wireless ...

Compared with 802.11ac, 802.11ax proposes a new spatial multiplexing technology, which can quickly identify air interface conflicts and avoid them. At the same time, it can more effectively identify interference signals and reduce mutual noise through dynamic idle channe...

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...

The full name of the optical module is optical transceiver, which is an important device in the optical fiber communication system. It is responsible for converting the received optical signal into an electrical signal, or converting the input electrical signal ...
