No Comments10G and 40G technologies have matured and occupied a large market during the past decade. While in recent years, 25G/50G/100G technologies are catching more and more attention and begin to stand out in future network deployments. These emerging Ethernet technologies are not simply designed to set a new higher speed [ Continue reading…]
What Are The Differences between SONET,SDH and DWDM?
No CommentsWhen compared with traditional SONET or SDH, the next generation of DWDM (Dense Wavelength Division Multiplexing) is seen as a simple architecture with high scalability, capacity add/drop, multiple ring terminations, multi-services, and multiple fabrics. Then, on comparison of SONET vs SDH vs DWDM, what are their differences exactly? SONET [ Continue reading…]
Introduction of 18 Channel CWDM Mux/Demux for 10G Network
No CommentsImagine turning a cottage into a majestic skyscraper without any innovation or construction. This is what Wavelength-Division Multiplexing (WDM) allows with your existing fiber optic network. Without deploying additional optical fiber, WDM network mux multiplexes multiple optical signal on a single optical fiber by using different wavelengths, which greatly relieves [ Continue reading…]
What the different between LED and Laser Light Source?
No CommentsAs the wide application of fiber optic system, optical light source plays a more and more important part in it. We known a basic optical fiber system consists of a transmitter, an optical fiber and a receiver. The fiber optic light source, as an important component of the transmitter is [ Continue reading…]
Can 10Gb Switch Port Link to Gigabit Switch Port?
No CommentsWhen beginning the transition from 1G to 10G network, many network switch users have encountered the issue of SFP to SFP+ compatibility. Will 1G SFP optics work with 10Gb SFP+ ports on a 10Gb switch? Or will 10Gb SFP+ run at 1Gb to link gigabit switches? What if using SFP+ [ Continue reading…]
The best way to Measure the Output Power of Transceiver Module
No CommentsThe best way Before shipment of the fiber optic transceiver, several tests are necessary to ensure transceiver can provide reliable operation, including the testing on the parameters of the transceiver module, such as output power, receiver sensitivity, working temperature, bias current, etc,. The output power, for instance, is a critical [ Continue reading…]
Brief introduction of DWDM Technology and DWDM System Components
No CommentsTelecommunications makes wide use of optical techniques in which the carrier wave belongs to the classical optical domain. The wave modulation allows transmission of analog or digital signals up to a few gigahertz (GHz) or gigabits per second (Gbps) on a carrier of very high frequency, typically 186 to [ Continue reading…]
