SFP + Application Of Ethernet Fiber Optic Data Communications

- Jun 30, 2017-

SFP + Advantages:

1, SFP + has a more compact form factor (same size as SFP) than X2 and XFP packages;

2, and the same type of XFP, X2, XENPAK direct connection;

3, the cost is lower than XFP, X2, XENPAK products.

Differences between SFP + and SFP:

1, SFP and SFP + appearance of the same size;

2, SFP protocol specification: IEEE802.3, SFF-8472;

Differences between SFP + and XFP:

1, SFP + and XFP are 10G fiber modules, SFP+ and with other types of 10G modules can communicate with each other;

2, SFP + smaller than the XFP appearance size;

3, because the smaller size of the SFP + signal modulation function, serial / deserializer, MAC, clock and data recovery (CDR), and electronic dispersion compensation (EDC) function from the module to the motherboard;

4, XFP compliance protocol: XFP MSA protocol;

5, SFP + compliant protocols: IEEE 802.3ae, SFF-8431, SFF-8432;

6, SFP + is more mainstream design.

7, SFP + protocol specification: IEEE 802.3ae, SFF-8431, SFF-8432.

SFP + is a new generation of 10 Gigabit optical module, which in accordance with the ANSI T11 protocol, to meet the Fiber Channel 8.5G and Ethernet 10G applications. SFP + is about 30% smaller than the earlier XFP optical module, and looks like an ordinary 1-4G SFP optical module. SFP + only retains the basic electro-optical, SFP+ photoelectric conversion function, reducing the original XFP design SerDes, CDR, EDC, MAC and other signal control functions, thus simplifying the 10G optical module design, power consumption and thus smaller. SFP + has the advantages of high density, low power consumption, lower system construction cost and so on. The product is widely used in the field of 10 Gigabit Ethernet optical fiber data communication, which is the mainstream product of 10GU module. F-tone can create a full range of 10G SFP +, including:

SFP + 10GBASE-SR 300 m (multimode OM3 fiber);

SFP + 10GBASE-LRM multimode fiber 220 meters;

SFP + 10GBASE-LR single-mode fiber 10-20 km;

SFP + 10GBASE-ER single-mode fiber 40 km;

SFP + 10GBASE-ZR single-mode fiber 80 km;

SFP + 10GBASE-EZR single-mode fiber 120 km;

18 band CWDM SFP +;

40-band DWDM SFP +;

BIDI SFP + ...
