The difference between Gigabit Light Module and Traditional Light Module.sfp transceivers module

The difference between the Gigabit Light Module and the Traditional Light Module is as follows:

① Differences on packaging.

Gigabit light modules include SFF.SFP.SFP+and XFP packaging. The traditional number of light modules mainly include sfp.sfp+.sfp28.qsfp+.qsfp28.

② The working wavelength is different.

The working wavelength of the Gigabit Light Module is mainly 1310NM.1490Nm. Regardless of single fiber or dual fiber, the traditional digital light module is divided into single fiber and double fiber. The working wavelength of a single fiber is mainly 1310NM.1490nm.1550Nm.

③ The working speed is different.

The working rate of Gigabit Light Module is mainly low speed, mainly 10G and below, and the working rate of traditional number of light modules is 155m.1.25g.10g.25g.40g.200g.400g or even 800G;

④ Different transmission distance.

The transmission distance of the Gigabit Light Module can only reach 20km, and the transmission distance of the traditional number of light modules can now reach more than 100km;

⑤ Different transmission methods.

The traditional digital light module adopts point -to -point transmission, module is used in pairs, single -workers or dual -work optical fiber link transmission, gigabit light modules use point -to -point transmission, modules are not used in pairs, saving costs than traditional digital modules, mainly used for connecting to connecting Enter the network;

⑥ The interface type is different.

The interface type of Gigabit Light Module is SC interface. The traditional number of interface types commonly used by the traditional number of light modules include LC.MPO.SC;
