What are the types of long-distance transceiver modules
نوشته شده توسط : ewr

Among SFP , SFP+ , XFP , 40G, and 100G transceiver modules , there are long-distance transceiver modules. Among them, the long-distance SFP+ optical module uses EML laser components and photodetector components. Various improvements have reduced the power consumption of the optical module and improved accuracy; the long-distance 40G optical module uses a driver and modulation unit in the transmit link to receive The link uses an optical amplifier and a photoelectric conversion unit, which can achieve a maximum transmission distance of 80km, which is far greater than the optical transmission distance of the existing standard 40G pluggable optical module

In the actual use of long-distance transceiver modules, in many cases, the maximum transmission distance of the module cannot be reached. This is because a certain degree of dispersion will occur during the transmission of optical signals in the optical fiber. To solve this problem, long-distance transceiver modules use Only one dominant wavelength is the DFB laser as the light source, which avoids the problem of dispersion.

SFP ,SFP+ , XFP ,25G ,40G and 100G transceiver modules have long-distance transceiver modules. Included in this, the long-distance SFP+ transceiver modules uses EML laser parts and photodetector components, which reduces the energy consumption of the optical module and improves the accuracy; the long-distance 40G optical module runs on the driver and a modulation unit in the transmit link, and receives The link uses optical amplifiers and photoelectric conversion units to achieve a maximum transmission distance of 80km
