Choose the sfp module types suitable for yourselves

There are a variety of ways to classify SFP fiber optic transceiver according to each parameter of the SFP module.

 

Firstly, SFP fiber optic modules can be divided into 155M, 622M, 1.25G, 2.5G and 4G optic modules according to the data rate.

 

Secondly, if according to the working wavelength, there are 850nm SFP modules, 1310nm SFP modules, 1490nm SFP fiber optic transceiver and 1550nm SFP modules commonly.

 

Thirdly, SFP fiber optic modules also can be divided into LC SFP modules, SC SFP modules and RJ45 SFP modules according to the types of interfaces.

 

Lastly, we will classify many types of SFP modules on the basis of the transmission distance from 550nm to 120km.

 

In conclusion, we should choose and by the SFP modules on the basis of our demand. Welcome to consult with our online customer services for any questions.

SFF Module

SFF module is another branch of the development of the fiber optic transceiver module. Currently, the SFF modules are widely used in the ONU of EPON systems. Since the ONU products of EPON systems are usually placed in the client which needs the ONUs be fixed, not hot-pluggable, the SFF is popular in EPON systems. And with the rapid development of EPNO technology, the SFF market share is also gradually expanded.   

XENPAK Module

XENPAK is an important step in the evolution of the optical modules. The XENPAK architecture provides a XAUI interface for the Media Access Controller.Compared with not hot-pluggable modules, XENPAK modules is very attractive. But is can’t meet some important market demand. The power consumption of XENPAK is usually 10W, which will cause a certain influence to the structure size because it increase the cost of manufacturing printed circuit board and reduce the precious line space.

X2 Module

X2 modules also adopt the XENPAK electrical interface, but there are a few local exceptions. X2 offers a 4bit port address space, a bit less than XENPAK. X2 also reduces the number of power supply pin. In the aspect of optical technology, X2 supports 10GbE, OC192 synchronous optical network, 10GFC and other standards.
