New Products For May - SFP+ Transceivers
What is an SFP+ transceiver?
A SFP+ transceiver is different compared with a typical SFP transceiver. The 10G module has been developed from 300Pin. XENPAK, X2, XFP and finally made in the same size as a SFP which has the capacity to transmit 10G signals, and hence called a SFP+ transceiver. SFP Definition. In a modern business context, the small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver commonly used in both telecommunication and data communications applications.
Sourcing SFP+ transceiver module from OnisNetworking
OnisNetworking has over 5 years experience in supplying the market and clients with SFP+ transceiver module. Rapidly gaining the trust of multi-national corporations and SMES from around the world, we supply the SFP+ optical transceiver product while providing premium services. For a guaranteed peace of mind, all our SFP+ optical transceiver products have been thoroughly tested before being shipped.
10 Gigabit Ethernet
The 10 Gigabit Ethernet (10GE, 10GbE, or 10 GigE) is an established group of computer networking technologies for the purpose of transmitting Ethernet frames at a stipulated rate of 10 gigabits each second. This was first defined by the IEEE 802.3ae-2002 standard in our industry. Different from the previous Ethernet standards, the 10 Gigabit Ethernet defines only full-duplex, and point-to-point links which are generally connected by network switches. Customers and user should note that shared-medium CSMA/CD operation has not been carried over from the previous generations of Ethernet standards. Consequently, half-duplex operation as well as repeater hubs do not exist in 10GbE.
More specifically, the 10 Gigabit Ethernet standard actually includes a variety of different physical layer (PHY) standards. For a networking device, such as a switch or a network interface controller, it might very well have different PHY types through pluggable PHY modules, such as those based on the SFP+. Much like earlier versions of Ethernet, the 10GbE can use either copper or fiber cabling. The maximum distance of over copper cable is 100 meters, but due to bandwidth requirements, a higher-grade cable are often required.
Looking back in our industry, the adoption of 10 Gigabit Ethernet has been more “gradual” than previous revisions of the Ethernet. To illustrate some figures for our clients, in the year 2007, a total of 1 million 10GbE ports were shipped, in the year 2009, 2 million ports were shipped, and in the year 2010, more than 3 million ports were shipped. This trend has continued and it is estimated that 9 million ports were shipped for the year 2011. As of 2012, even though the price per gigabit of bandwidth for 10 Gigabit Ethernet was about one-third compared to Gigabit Ethernet, the price per port of 10 Gigabit Ethernet still hindered a more widespread adoption rate.
