Transmission rate is a crucial factor in determining the type of Ethernet Switch port. At present, the transmission rate of Ethernet switches is 1G/10G/25G/40G/100G or even higher. The following are the mainstream port types of these Ethernet switches with dif...

How to measure the network delay in an Ethernet switch? As can be seen from the previous chapter, switch delay is one of the key factors leading to network delay. So how do we measure switch latency? Switch delay is measured from port to port on the Ethernet s...

Network latency refers to the network waiting time, which refers to the round-trip time for a data packet to be sent from the user's computer to the website server, and then immediately from the website server to the user's computer. Network delay is one of t...

Power Over Ethernet (PoE) is a power supply technology based on a local area network (LAN), which can transmit power and data to the device through a network cable in the Ethernet. The application of this technology can greatly reduce operating costs and save ...

Currently, most switches on the market, especially old switches, only use a single power supply. If the power supply fails (such as power failure), the switch cannot operate normally, or even paralyze the network.Redundant power supplies are an ideal solution ...

Why are SFP optical modules popular? The volume of the SFP optical module is reduced by half compared with the volume of the GBIC optical module. The number of SFP ports on the same panel will be twice that of the GBIC optical module. The same SFP optical modu...

What is SFP module? The SFP module is an interface device that converts gigabit electrical signals into optical signals. It is an industry-standard small and pluggable gigabit optical transceiver module that can be plugged into the SFP of network equipment suc...

The safe transmission distance of POE power supply is 100 meters, and it is recommended to use Cat 5e copper network cable. It is possible to transmit DC power with a standard Ethernet cable for a long distance, so why is the transmission distance limited to ...

Multi-channel digital video optical transceivers can have multiple functions, and each type of function has corresponding technical index requirements, such as video index, audio index, asynchronous data index, Ethernet index, telephone index and so on. Speci...

    Optical transceivers are also optical signal transmission equipment. Foreign optical transceivers have mature technology but are expensive. Although domestic optical transceivers are not so mature in technology, they are not expensive enough to deal with...
