Fiberstore Introducts The SFP+ Transceiver Advantage

Recently, with the growth and development of the network, more and more people begin to pay attention fiber industry.One of them, optical transceivers within the network plays a crucial role.The Fiber Optic Transceiver is definitely an Ethernet converting a power signal into an optical signal or perhaps an optical signal is changed into an Ethernet electrical signals with the photoelectric conversion apparatus, to change electrical signals to optical signals inside a multi-mode or single-mode optical fiber transmission, Break through short cable transmission distance limited / system, Ethernet beneath the premise of ensuring the transmission of high-bandwidth, fiber media to accomplish a few kilometers as well as hundreds of kilometers of long-distance transmission. Create a network of fiber optic transceivers can save network investment.

When it comes to fiber optic transceivers, how can we not introduce Cisco SFP+ . SFP + optical modules(10 Gigabit Small Form Factor Pluggable) is a hot-swappable, independent of the communication protocol optical transceiver, usually transmitted light wavelength is 850nm, 1310nm or 1550nm for 10G bps SONET / SDH, Fibre Channel, gigabit Ethernet, 10 gigabit Ethernet as well as other applications, including DWDM link. XFP contains similar SFF-8472 digital diagnostic modules, but extended use a powerful diagnostic tool.SFP+ optical transceiver is SFP sometimes called " mini-GBIC " upgrade. SFP+ will be the application of SFP in 10,000 new areas.

SFP + support SONET, Gigabit Ethernet, Fibre Channel (Fiber Channel), in addition to a quantity of other communications standards. This standard extensions towards the SFP +, can support 10.0 Gbit / s transmission rate, such as the 8 gigabit Fibre Channel and 10GbE.The creation of fiber optic and copper core version of the SFP + module version Xenpak, X2 or XFP sort of the module, the SFP + module area of the circuit to stay about the motherboard to attain, rather than a module.

Lots of people don't know the main difference sfp sfp +, so sometimes bring unnecessary trouble. The 10G module experienced from 300Pin, XENPAK, X2, XFP development, and eventually using the size the transmission and SFP 10G signal this is SFP +. SFP using its miniaturized low-cost benefits of meet the needs of high-density equipment, optical module, the implementation of the 2002 standard, 2010 has replaced the the XFP 10G market mainstream.

SFP+ Transceiver advantages:
First, SFP + has a more compact form factor than X2 and XFP transceivers (the same as the size to the SFP);
Second, and of the same type XFP, X2, XENPAK direct connection;
Third, cost than XFP, X2, XENPAK product low.

SFP + and SFP distinction:
1, SFP and SFP + appearance of the same size;
2, SFP protocol specification: IEEE802.3, SFF-8472;

SFP + and XFP distinction:
First, SFP + and XFP are 10G fiber module can communicate with each other and with other types of 10G module;
Second, SFP + is smaller than XFP Dimensions;
Third, because smaller SFP + signal modulation function, serial / deserializer, MAC, clock and data recovery (CDR), as well as electronic dispersion compensation (EDC) function from the module to the motherboard card;
Next,XFP compliance agreement: XFP MSA agreement;
The next, SFP + compliance protocol: IEEE 802.3ae SFF-8431, SFF-8432;
Last, SFP + is more mainstream design.
