In fiber optic communication,10G Optical Ethernet interface technology in recent years has been considerable development, However, due to the high cost, 10-Gbps application does not, as projected in the market spread rapidly. 10-Gbps technology based on copper wire is also plagued by low port density issues caused by the power loss and crosstalk, resulting in its market-oriented process difficult. In this context, the emergence of a new program. Solutions with high port density, low-cost SFP + optical transceivers for enterprise users to provide more cost-effective technology in the past 10-Gbps Ethernet upgrade.
As SFP+ (enhanced small form-factor pluggable) becomes more pervasive,we want to know it more and more easy.Just as its name implies, the SFP+ transceiver is an upgraded version of the small form-factor pluggable transceiver. The SFP+ Transceiver is more compact in size than its predecessors, X2, XENPAK and XFP, making it the perfect solution for higher port density installations. Fiberstore supply the SFP+ transceivers are also not only efficient, but cost effective, with a power consumption of less than 1W.
The SFP+ module is a variant of the SFP optical transceiver. The SFP+ module form factor is 30% smaller, uses less power, requires fewer components, and is less expensive than the 10-Gigabit small form-factor pluggable module (XFP) form factor, which was already smaller and used less power than the XAUI-based XENPAK and X2 form factors.
The SFP+ form factor significantly simplifies the functionality of the 10G optical module by moving such functions as clock and data recovery (CDR), electronic dispersion compensation (EDC), 10G SERDES, and signal conditioning that traditionally resided inside the XAUI-based modules into 10GbE PHY devices and line cards. As a result, the modules are smaller, consume less power, and allow increased port density while being less expensive than XFP. Some products on the market now offer 48 ports or more in a rack.
Each SFP+ module houses an optical transmitter and receiver. One end of the module is an SERDES framer interface (SFI) serial interconnect, which handles differential signals up to 10 Gbits/s. The other end is an optical connection that complies with the 10GbE and 8GFC standards. The SFP+ active cable has electrical input and outputs with an optical transmitter and receiver internal to the cable. Active cables with SFP+ terminations also can be copper-based with integrated pre-emphasis and equalization..
