How to select dual fiber optical module and single fiber optical module?

Both single fiber and dual fiber optical modules can transmit and receive. Since the two communications must be able to transmit and receive. The difference is that a single fiber optical module has only one port. Wavelength division multiplexing (WDM) technology is used to combine different rece... Read More

Difference between dual fiber optical module and single fiber optical module

1. Different appearance:  Double fiber optical module: There are two optical fiber sockets, respectively, the sending (TX) and receiving (RX) optical ports. Two optical fibers need to be inserted, and different optical ports and optical fibers are used for data transmission and reception; When du... Read More

How to view optical module DDM information

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... Read More

Optical module DDM function application

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... Read More

What is the DDM in the optical module?

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 ... Read More

Introduction to WiFi Calibration Parameters

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 ... Read More
