DWDM System Helps Expand the 10GbE Network

Dense Wavelength Division Multiplexing (DWDM) network is regarded as the 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 to 80km. However, the transmission distance of fiber optical network will be affected by factors like date rate, optical signal loss, etc. This article will introduce three instances of how…

Introduction to 10GbE/25GbE/40GbE/100GbE Fiber Optic Cabling

Technology is changing rapidly. Just when you got used to Gigabit Ethernet speeds being a fast & reliable system, someone unveiled 10GbE, 25GbE, 40GbE or even 100GbE systems a few years later. The newer and higher performing iterations are indeed the great breakthrough for telecommunication industry, but also pose difficulty in choosing network migration path—10G to 40G to 100G, or to 25G to 50G to 100G. We have described 10G, 25G, 40G and 100G Ethernet technology before, now in this blog, we’d like to introduce the four fiber optic cabling,…

Comparing 10GBASE-T SFP+ Transceiver Module With SFP+ SR/LR Optics & SFP+ DAC Twinax Cables

1000BASE-T SFP modules are available on the market as soon as the certification of Gigabit Ethernet network. However, 10GBASE-T SFP+ modules, owing to the technology limit, have not been supplied by vendors to support 10G copper networks. Instead, IT managers tend to use the cost-effective SFP+ direct attach cables (DAC) for short-reach 10G applications. Today, here comes a big news—vendors like HPE, Prolab, and FS.COM begin to offer 10GBASE-T SFP+ transceiver modules. Do you feel curious about them? This article will unveil the mysterious point of the 10G copper transceivers,…
