Review: Popular 24-Port PoE Switch for Different Size Networks

Purpose built for converged networks where video, voice, and data are carried over a single network platform, PoE switches with 8 port, 24 port, and 48 port represents an ideal solution for different size networks like home or SMBs (small and mid-size business networks). 24-port Gigabit PoE switch is a relatively commonly used network switch, which in turn cause hot…

GPON applicatiion in FTTH

What Is the Difference Between EPON and GPON?

With the prevalence of FTTH (Fiber To The Home)in the access networks, PON (Passive Optical Network) naturally plays a key role in it. To further keep pace with the demands, EPON (Ethernet Passive Optical Network )and GPON(Gigabit Passive Optical Network) emerges from PON and become popular versions of it. Maybe one is confused about the difference between EPON and GPON….


How to build 10G Network Within Budget

Modern business has become increasingly digital for cloud and data center application, which means everything from sales and marketing to service and support, rely heavily on a fast and reliable network. In 2017, the Gigabit Ethernet data rate is no longer adequate to support your business in the ever-developing digital world. Therefore, more and more people nowadays prefer to migrate…

Basics of DWDM Concepts

DWDM System Helps Expand the 10GbE Network

Dense Wavelength Division Multiplexing (DWDM) network is regarded as a feasible solution to achieve long-distance fiber expansion. DWDM system, with the channel density of 96, has much narrower channel spacing than CWDM system, which allows extremely high utilization of a single fiber strand to pass up to many clients. 10G DWDM SFP+ modules can support a link length of up…

250um Loose-tube vs. 900um Tight Buffered Fiber

There are two common styles of fiber optic cable constructions; 250um loose-tube and 900um tight-buffered fiber, but they are designed for different usage. So how to choose between them?


The basics of Ethernet

In today’s telecom field, Ethernet has been utilized at various levels of the control hierarchy. Since the standardization in 1980, Ethernet has become the most widely installed local area network (LAN) technology either in the office or the enterprise network for the high-end controller. We talk about Ethernet every day, however, people without decades of experience can hardly say they…
