SFP-GE-LX-SM1310 Gigabit single-mode optical module is a very widely used gigabit optical module. The Gigabit single-mode package type is SFP, the transmission rate is 1.25G, the center wavelength is 1310nm, and the transmission distance can reach 10km when used with single-mode fiber. Gigabit single-mode optical modules support hot-swappable and low loss. Next, I will introduce some basic knowledge of the SFP-GE-LX-SM1310 Gigabit single-mode optical module.

principle:

The working principle of gigabit single-mode is photoelectric conversion. The sending end converts electrical signals into optical signals, and after transmission through optical fibers, the receiving end converts optical signals into electrical signals. The transmitting part is: the electrical signal of a certain code rate is input and processed by the internal driver chip to drive the semiconductor laser (LD) or light-emitting diode (LED) to emit a modulated optical signal at a corresponding rate. It has an optical power automatic control circuit inside, so that The output optical signal power remains stable. The receiving part is: an optical signal with a certain code rate is input into the module and then converted into an electrical signal by a light detection diode.
