What is a fiber optic switch? And what are the types of fiber optic switches? A fiber optic switch is a high-speed network transmission relay device. Compared with ordinary switches, they use fiber optic cables as the transmission medium. The advantages of optical fiber transmission are fast speed and strong anti-interference ability.

The development of PoE power supply technology is gaining momentum. With its advantages of simplified installation of electrical equipment, deployment, energy saving and safety, PoE technology has been widely used.Today we will sort out the frequently asked questions and answers about PoE switches.

The most common equipment in network equipment maintenance is network switches, especially the access layer switch. Connecting users and switching routing devices, as an intermediate, network switches play a vital role in troubleshooting network failures. Here are some common faults and solutions for switches.

Stackwise Technology, an innovative stacking architecture, is used on Cisco 3750 Series switches to provide 32Gbps stacking interconnect. It can connect up to 9 switches and turn them into a unified, logical and convergence-optimized device so that users can deploy voice, video and data application comfortably. Cisco 3750 series switches adopt the way of backplane bandwidth stack, and the models themselves have stacking ports and can reach 32G backplane bandwidth by using specific stacking lines

There are 2 channels internal network in the company, FW1 and FW2 set as enterprise dual output firewall, internal network runs OSPF contract with firewall, output firewall works as load sharing, Vlan 10 through AR1, Vlan 20 trough AR2.

When someone talk about Cisco router, or Cisco switch with me, I’m very confused about this. Router? Switch? What are they? What are they used for? Oh, My Lady Gaga, complicated.

​Nowadays, people must be familiar with the router. At that time, the router was popular and purchased by many people. This article is mainly about Cisco routers, which are an integrated multi-service router, a welfare integrated service network router, and a rewarded network router. So what are the advantages of Cisco routers? What is the price? how to choose? Follow the small series to find out.

Status: The network room gateway is a separate cisco 3750G switch. Once the physical device has problems, the entire network will be at risk.

The Cisco Catalyst 2960 series switches and routers provide services for conventional office, branches, workspaces, medium-sized deployments and infrastructure networks.

Due to price and functionality, there are many different models of Cisco routers. Here we simply divide the cisco router types into low-end and high-end products.

VLANs are a mechanism to allow network administrators to create logical broadcast domains that can span across a single switch or multiple switches, regardless of physical proximity. This function is useful to reduce the size of broadcast domains or to allow groups or users to be logically grouped without the need to be physically located in the same place.

Are you confused if I need a switch or router for the wireless network? Don't worry, here we tell you the 5 difference between switch and router.
