Differences between the RJ45 port and the SFP port of the switch

We know that in the present market, Gigabit Ethernet switches generally have two ports: RJ45 port and SFP port, both of which can be transmitted with Gigabit Ethernet. Then what are the differences between the two ports? How should we wire them respectively? This tutorial will answer one by one.Gigabit Ethernet switch’s RJ45 port and SFP portIn order to meet the growing network needs, network upgrade in the machine room of the data center or server is urgent. Therefore, Gigabit Ethernet has become increasingly common. So, what kind of port Gigabit switch should be used to achieve Gigabit Ethernet connection? The following is the introduction to two ports in detail:RJ45 portGigabit Ethernet switch’s RJ45 port is a built-in port. To connect two RJ45 port Gigabit Ethernet switches, we only need to use a super five or six cable. The following table is the specific rate and bandwidth of this connection:    Shielded level Maximum transfer rate(distan..

Select the right and good pre-terminated trunk cable, so easy!

Pre-terminated trunk cables are typically used in the connection of trunk and crossover cabling in the data center. This pre-terminated cable simplifies the installation process, saves time and labor costs compared to field termination. Now there are variety of pre-terminated trunk cables in the market, how to choose the appropriate pre-connected trunk cable products? Here, we will detail the pre-terminated trunk cable flame retardant grade, connector type and application examples in three areas, hoping to provide some help in the purchase of pre-terminated trunk cable for you.1, the cable material In the purchase of pre-terminated trunk cable, we must first consider the cable laying environment, which involves what kind of flame retardant cable we should buy. Pre-terminated main cable common flame retardant grades are Riser (trunk level), Plenum (booster level) and LSZH (low smoke halogen-free grade). Although the three are not significantly different from the appearance, but the Rise..
