In the later year of 2011, Cisco launched 3750 Series switch, with a purpose to improve LAN operating efficiency and resiliency for stackable switches. Cisco Catalyst 3750-X Series is one series of Cisco 3750 Series, which featured as high availability, scalability, security, energy efficiency, and ease of operation. The detailed information about Cisco Catalyst 3750-X Series switch would be provided in this article. In addition, we will guide you to plug your optical modules into this switch, all the installation and removing procedures as well as cautions are fully covered in the following passage. Overview on Cisco Catalyst 3750-X Series switch Cisco Catalyst 3750-X Series switch are 12-port and 24-port Gigabit Ethernet Small Form-Factor Pluggable (SFP) switches. You can see it more clearly in the following figure. Different from the traditional switch design, they additionally added some other functions, such as four optional network modules, redundant power su...

Most us of us may quite familiar with 10G, 40G and 100G Ethernet network, but we know little about 25G Ethernet, or even never heard about it. In the race of 10G, 40G and 100G Ethernet, it seems that 25G Ethernet lagged far behind. However, it is a good choice for network connectivity indeed. So what is 25G Ethernet and its benefits? And what about its cables and optical modules? The detailed information about 25G Ethernet would be provided in this article. Overview on 25G Ethernet Researched and developed by IEEE group, 25G Gigabit Ethernet is a standard for Ethernet connectivity. Compared with 10G, 40G and 100G Ethernet, 25G and 50G Ethernet were the latest developed Ethernet specification. 25G Ethernet Consortium was formed in July 2014 to support the specification of single-lane 25G Ethernet. It is an open organization to all third parties who wish to participate as members to enable the transmission of Ethernet frames at 25 or 50 Gigabit per seconds (Gbps) and...

Over the years, 40G and 100G networks are developing rapidly, but nearly all new network building or network upgrading are based on 10G network. As an indispensable part in 10G network building, 10G optical transceiver has been designed and standardized by IEEE group as early as 2006. Compared with the prevalent 10GBASE-SR, 10GBASE-LR optical modules on the 10G transceiver market, 10GBASE-T SFP+ copper transceiver receives little attention. Different types have their own pros and cons, so why should we choose 10GBASE-T SFP+ transceiver for 10G network connection instead of others? This article would provide a satisfying answer for you. Basic Information About 10GBASE-T SFP+ Transceiver 10GBASE-T meets all the bit-error rate (EDR) requirements of all the Ethernet and storage over Ethernet specifications, which is specifically designed for high speed communication links that require 10G Ethernet over cat6a or cat7 cable. It uses the familiar RJ45 connector and provid...
