The optical module DDM is a means of monitoring parameters. It has not only alarm and warning functions, but also fault prediction and fault location functions. There are two main methods to view the DDM information of the optical module: SNMP and command. 1. SNMP, namely Simple Network Managemen...

1. Optical module life prediction Through the real-time monitoring of the working voltage and temperature inside the transceiver module, the system administrator can find some potential problems: a. If the Vcc voltage is too high, it will bring breakdown of CMOS devices; Vcc voltage is too low, a...

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...
