What is the effect of the SFP light module?Fiber optic equipment manufacturer

The SFP optical module is the hot plug -in packaging control module of the SFP packaging. At this stage, the GAO speed can reach 10.3G, and the socket is LC. The key of the SFP light module is composed of laser generator. There are also, the composition of the SFP light module is: laser generator: including the FA shooter TOSA and the signal receiver ROSA; PCB line board IC; external parts include: case, base, PCBA, bottle cap, locks, buckle, buckle, buckle Turn on and rubber. Moreover, the SFP light module can be classified according to speed, light waves, and methods.

Speedy

According to the speed score is 155m/622m/1.25g/2.125g/4.25g/8g/10g, 155m and 1.25G sales markets are placed more. trend.

Light waves return

According to the length of the light waves is 850nm/1310Nm/1550Nm/1490Nm/1530nm/1610Nm, the light wavelength is 850nm is SFP multimodiability fiber, the transmission spacing is below 2km, the light wavelength is 1310/1550nm, the transmission spacing is above 2km. Relatively speaking, the price of these three types of light wavelengths is cheaper than other three.

If the naked control module is not marked, it is easy to confuse. Generally, manufacturers will be different from the color tone of the bottle cap, for example: the gray -black bottle cap is the multi -mode fiber, the light wavelength is 850nm; the dark blue is the light wave length of 1310nm Control module; *** is a control module with a light wave length of 1550nm; blue -purple is a control module with a light wave length of 1490nm.

Pattern classification

SFP light module multi -mode optical fiber

Basically, all the single -mode fiber specifications are 50/125um or 62.5/125um, and the network bandwidth (information content transmission of the optical fiber line) is generally 200MHz to 2GHz. Multi -mode optical ends can be transmitted by nearly 5 kilometers according to the single -mode optical fiber. Taking the light emitting diode or laser generator as the lamp source. The bottle cap is gray -black.

SFP light module

The specifications of the single-mode are 9-10/125 μm, and compared with the single-mode fiber, it has the characteristics of unlimited network bandwidth and less consumed. Multi -mode light -ending machines are mostly used for long -distance transmission, sometimes 150 to 200 kilometers. Use LEDs with LEDs with LEDs with LD or spectral lines as the source of the lamp.
