Transmission Mode of PON Optical Module
PON transmits Ethernet, Asynchronous Transfer Mode (ATM), and Time Division Multiplexing (TDM) traffic. A PON module is an optical transceiver specifically designed for Passive Optical Network applications. Unlike active optical components requiring power, PON leverages passive splitters, making the modules in the Optical Line Terminal (OLT) at the provider's end and the Optical Network Unit (ONU) or. PON networks enable simultaneous access for multiple users over a single optical fiber, supporting point-to-multipoint (P2MP) transmission. Data transmission from the OLT to the ONU is defined as downstream, while transmission from the ONU to the OLT is upstream; full-duplex transmission is adopted. A PON module, or Passive Optical Network module, serves as a pivotal device in telecommunications networks, facilitating the transmission of data, voice, and video signals over fiber optic cables. The PON module is the core component to realize fiber access such as FTTH (Fiber-to-the-Home), FTTB (Fiber-to-the-Building), and FTTO (Fiber-to-the-Office). In PON, WDM enables the. The ITU-T has proposed standards for ATM-PON (G983. 1) and B-PON (Broadband-PON) (G983. 1 relates to networks with a transmission path rate of 155 Mb/s or 622 Mb/s. 3, these signals are multiplexed with CATV or other video signals. -
