A Brief Introduction of Cisco BiDi SFP Transceiver

In the early stage of optical fiber communication, one optical fiber can only transmit signals of one wavelength. This is known as conventional two-fiber Bi-Directional communication – at least two fibers are needed to accomplish the full-duplex communication with TX and RX optical signals. With the development of WDM technology, transmitting and receiving of optical signals on separate wavelength can…

Why Is a 10GBASE-T SFP+ Copper Transceiver Needed?

The growing use of virtualization in data centers has addressed the need for 10G Ethernet as a way to reduce the complexities when using the existing 1G Ethernet infrastructures. Moving to 10G Ethernet has a number of choice from 10GbE interfaces including CX4, 10G SFP+, SFP+ direct attach copper (10G SFP+ Cu) and 10GBASE-T. However, 10GBASE-T is perceived as a…

Wireless Access Point: 2.4 GHz or 5 GHz?

Wireless networks have come a long way in the past couple of decades. And yet, sustained Wi-Fi speeds are still a vexing problem in a lot of situations. If you are looking for a solid way to increase the efficiency and productivity of your business in terms of Wi-Fi access, a wireless access point should be strongly considered. Do you…

A Beginner’s Guide to RJ45 Connector

Generally, cables can transmit information along with their length. To actually get the information where it needs to go, you need to make the right connections to an RJ45 connector. Your cable run needs to terminate into a connector, which needs a jack to plug into. RJ45 is a standard type of physical connector for network cables, which is especially…

Compatible Optical Transceivers for Cisco Catalyst 9500 Switches

According to a recent survey, over half (57%) of companies have already adopted the Internet of Things (IoT) technology. By 2019, that statistic is projected to reach 85% as the expectations for IoT to deliver value and innovation continue to grow. Many advocates are struggling to secure IoT devices. To lead the pack in the switches markets, Cisco recently announced…

How to Choose a Suitable Network Switch?

A network switch is a small hardware device that centralizes communications among multiple connected devices within one local area network (LAN). Network switches come in different sizes, features, and functions, so choosing a switch to match a particular network sometimes constitutes a daunting task. This blog will give you a few useful things to consider when choosing the appropriate switch…
