How to disable the SFP module on H3C vswitches and other devices? The following warning is displayed: OPTMOD/4/PHONY_MODULE: GigabitEthernet1/0/2: This transceiver is NOT sold by H3C. h3C therefore shall NOT guarantee the normal function of the device or assume the maintenance responsibility thereof! This is a warning when SFP module is used on H3C vswitches, rou
What are the advantages of a small pluggable (SFP) port for a Gigabit Ethernet switch?
How do I connect the four SFP ports of a d-link DGS 1248 t smart switch?
I think the main advantage of the SFP port is the flexibility to connect to the network. The SFP port is a hot-swappable input/output device that can be plugg
One end of the optical transceiver is connected to the optical transmission system, and the other end is the 10/100 M Ethernet interface. Optical fiber transceiver achieves photoelectric signal conversion. The main principle of the optical transceiver is achieved through photoelectrical coupling.
Optical Transceiver ge
The SFP is the abbreviation for the small FORM pluggable and can be easily understood as an upgraded version of the Gbic. The SFP module is half the size of the Gbic module, and can be configured with more than one port number on the same panel. The other features of the SFP module are basic and gbic consistent. Some switch vendors call the
1. What is GBIC?
GBIC is short for Giga Bitrate Interface Converter. It is an Interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBIC is an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange.

These days, when HP acquired H3C, it was rare to see 3COM with 3 O-markers. But the problem, a year ago a project bought a 3COM switch 2924-SFP plus switch (PS: pure switch, no readable data). At that time saw a default management IP in the back, so log in to the Web interface configuration can be. Later the project bought H3C S5500 switch, do not have this switch, so idle.Due to the recent equipment is more tense, need to enable, the problem came, bu

receive side.To achieve this function, the TX sender adds an identical channel binding sequence to the transmitted data stream, and the RX receiver makes corresponding adjustments and delays in the respective Rx elastic buffers based on the channel binding sequence detected by each lane, eventually making the data in each lane non-existent, in the FPGA RX The output of the interface can be the same as the data sent by the TX sender, with misaligned data on the left and aligned data on the right
Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of optical fiber, wavelength, interface type, rate, and other technical indicators, a wide range of Optical Fiber transceive
Introduction
In the domestic common information development and implementation projects, most of the work of the development of the workload is concentrated in order to adapt to different customer needs, the specific modules to modify, and ultimately achieve customer expectations of the software functional characteristics. But for the development of vendors, in the face of different customers to develop different software versions, will lead to duplication of labor, cost rise, maintenance incre
1. Similarities
1.High-speed can transceiver, can reach 1 mbaud
2.Can all enter the standby mode
3.Both have strong anti-interference capabilities
4.Both features hot shutdown (overheating protection)
5.When txd (Pin 1) is high, the output bus is in the implicit (recessive) state. When txd is low, the output bus is in the dominant (dominant) state.
6.Differential voltage VI (DIF) = VCANH-VVANL, when vi (DIF)> 0.9v, the bus is dominant; VI (DIF) Ii. Di

1. Transceiver Service Analysis Summary
Transceiver Service is the core of the transceiver system, transceiver kernel is responsible for reading the port, transceiver definition and parameter
When using a fiber-optic transceiver, it is necessary to pay attention to some problems in order to make the use of fiber-optic transceiver better.
1. View whether full duplex or half-duplex is supported.
Some of the market can only use a full dual public environment, can not support Half-duplex, such as receiving other brands of switches or hubs, and it uses Half-duplex mode, otherwise it will cau
Indication of the indicator meaning:Power (green): "Solid" indicates that the fiber transceiver is in power state;LFP indicator: "Solid" indicates that the LFP function is turned on, "normally extinguished" means that the LFP function is closed;Fx_link/act (green): "Solid" indicates that the fibre port connection is valid, "flashing" indicates that the transceiver is receiving or transmitting data from the
Network Office has become the trend of modern enterprise development. This paper mainly expounds the function module of the transceiver management system based on B/s structure and how to use ASP and SQL Server to solve some related technologies, including the security of the system.
Introduction
Traditional manual Office is unable to meet the needs of modern office, transceiver management system as to impr
Previous wrote a serial assistant with QT to do the blog post (based on Qt5.6 do a simple serial port with the transceiver function), do out of the serial assistant can only carry out the character of the transceiver, if the reception is the hexadecimal data, it will show garbled, and now on its basis to do some modification, so that the implementation of hexadecimal tr
In the wireless data transmission system, the wireless transceiver chip is the core carrier of the technology. As the signal sending and receiving, modulation, and debugging, it plays an absolute core role. We will compare and analyze several Wireless Transceiver Chip Solutions.

"Netizen asks a question": have been not clear exactly what difference does photoelectric converter, fiber transceiver, light cat, light module have?
"Answer": Optical module is inserted in the router or switch, can not be used independently, belong to other devices part.
and netizens mentioned (photoelectric converter, optical transceiver, light cat, optical module) A few things are basically one thing,
ObjectiveAbout the function of DMA (Direct Memory Access), the people who are concerned about me should know that I have briefly spoken on the F1 chip. There are netizens asked to explain in F0 the use of DMA transceiver serial data. Today should be a user request to summarize on the F0 chip, the use of DMA transmission (transceiver) Usart data functions.In a variety of chips (F0, F1, F2, F3, F4) know the f
