According to the different categories of development time:
Optical modules are classified into PON optical modules and traditional optical modules
When using traditional optical modules:
The optical signal transmission mode is point-to-point (P2P: that is, one to one), and the modules are used in pairs (such as TX13RX15 and TX15RX13 as a pair), and one or two optical fibers are used for transmission (this can be divided into duplex or simplex mode).
Fiber link loss includes attenuation, dispersion, fiber connection insertion loss, etc. The attenuation is mainly due to the absorption of light energy by the medium during the transmission process. Dispersion is caused by the broadening of pulses due to different transmission rates of light wavelengths. The traditional module has a long transmission distance, up to 200km; Because the cost factor is less used for access networks, it is mainly used in backbone networks.
When the PON optical module is used, the transmission mode of the optical signal is point-to-multipoint (P2MP: can be transmitted through the ODN), and the module is not used in pairs. Fiber link loss includes attenuation, dispersion, frequency division ratio loss, fiber connection insertion loss, etc. The transmission distance is shorter than the traditional module, the distance is only 20km; Mainly used in access network.
The above is the difference between PON optical module and traditional optical module brought by Shenzhen HDV Phoelectron Technology LTD. The module products produced by the company cover optical fiber module, Ethernet module, optical fiber transceiver module, optical fiber access module, SSFP optical module, SFP optical fiber module and so on. The above module class products can provide support for different network scenarios. For the above products, it is paired with a professional and strong R & D team to provide technical support for customers, and a thoughtful and professional business team to provide quality service for customers in the early consultation and later work.
