As a network engineer, RJ45 ports and SFP ports are often encountered. This article will introduce you to RJ45 and SFP. What is RJ45 The RJ45 port is the most common network device interface, commonly known as "RJ connector", and the technical term is RJ-45 connector. "RJ" is short for Registered Jack...
Hello everyone! This post will introduce you to the optical module encapsulation types. I believe you are interested. SFP/eSFP Optical Module Small form-factor pluggable (SFP) optical modules are compact, hot-swappable, low-speed optical modules. They comply with the specifications defined in the multi-source agreement (MSA) and support synchronous optical network (SONET), Gigabit Ethernet...
Hello, everyone! In today's article, I will explain the difference between the RJ45 port and the SFP port. Sounds interesting, doesn't it? Let's see! Network devices such as routers, switches, servers, OLTs, ONUs, etc. use RJ45 ports and SFP ports for communication. Network devices can have one or more RJ45 ports,...
Hello everyone! There are a number of different SM fiber optic standards. In today's article, I will explain the G.652, G.653, G.654, and G.655 standards. Let's familiarize ourselves with these standards! The following table shows the standards with a basic description that I will write about today. There are different standards that...
Hello everyone! Today's article is dedicated to SFP and SFP+ modules. I will give a short explanation of both modules with the most important features and in addition, I will show the most important differences between them. I have already written about similar topics in several previous articles. But now...
Precautions 1. For some boards, a converter needs to be installed on each QSFP28 optical module. The converter and the optical modules must be used together as one component and cannot be separated. 2. When you replace a pluggable optical module, query, whether the port of the optical module to be...
1. Checking the Optical Module Type Log in to the switch through Telnet or console port to check the switch model. Run the display device command to check the switch model. <HUAWEI> display device S3328TP-EI's Device status: //Switch model Slot Sub Type Online Power Register Status Rol - - - - - - -...
Issue Description How Do I View the Transmit and Receive Optical Power of an Optical Module? In V100R006C03 or V100R006C05 of fixed or modular switches The RX Power(dBM) field in the command output indicates the receive power of the optical module, and the TX Power(dBM) field indicates the transmit power. <Quidway> display transceiver...
