What is Passive Optical Networking (PON)?
Passive optical networking (PON) is a high-speed broadband technology that enables the delivery of multiple services over a single fiber optic cable. XGS-PON – 10G Symmetrical PON – offers speeds of up to 10 Gbps downstream and 10 Gbps upstream (hence the term ‘symmetrical’), making it ideal for applications such as video streaming, online gaming, and cloud computing.
What Problems Does PON Solve for Out-of-Band Management?
PON addresses the issue of efficiency in terms of both uplink costs and bandwidth usage. Traditional POTS lines and dedicated circuits rely on legacy infrastructure that requires regular maintenance. This infrastructure must scale as more out-of-band devices are added to the network, which increases costs and energy consumption. On top of this, using a 10G uplink for a serial console’s 10K traffic is like throwing away 99% of that high bandwidth. Per Gartner’s Market Guide for Optical Transport Systems report (Published 20 November 2023) the best way to “lower cost and energy per transported bit” is by using technologies such as passive optical networking.
Because PON uses passive optical splitters that have no moving parts or powered components between the central hub and end users, PON is much more
