PON Optical Module and Traditional Optical Module

According to the different classification of development time:

Optical modules are divided into two types: PON optical modules and traditional optical modules.

When using traditional optical modules: The optical signal transmission mode is point-to-point (P2P: one transmission to one), the modules are used in pairs (such as TX13RX15 and TX15RX13), and use one optical fiber or two optical fibers for transmission (this can be divided into duplex or simplex mode).

Optical fiber link loss includes attenuation, dispersion, fiber connection insertion loss, etc. Attenuation is mainly due to the absorption of light energy by the medium during the transmission process; dispersion is due to pulse broadening due to different transmission rates of optical wavelengths. The traditional module has a long transmission distance, up to 200km; due to the cost factor, it is less used in the access network, and is mainly used in the backbone network.

When using PON optical modules, the transmission mode of optical signals is point-to-multipoint (P2MP: can transmit multiple through ODN), and the modules are not used in pairs. Optical fiber link loss includes attenuation, dispersion, frequency division ratio loss, optical fiber connection insertion loss, etc.; the transmission distance is shorter than that of traditional modules, and the distance is only 20km; it is mainly used in access networks.

The above is the explanation of the difference between PON optical modules and traditional optical modules brought by Shenzhen HDV photoelectric Technology Co., Ltd.The module products produced by the company cover optical fiber modules, Ethernet modules, optical fiber transceiver modules, optical fiber access modules, SSFP optical modules, and SFP optical fibers, etc. The above module products can provide support for different network scenarios.
