Packet Optical Transport—A Viable Solution to Network Expansion


 

Discover additional materials:

Packet optical transport (POT) networks are optical super-highways that use the most advanced technological enablers, from reconfigurable optical add/drop multiplexers (ROADMs) to amplifiers—and from very high bit rates to dense wavelength-division multiplexers (DWDMs).

The need to shift from time-domain multiplexing (TDM)-based networks to packet-friendly infrastructures that support digital voice, video, Internet and other related services is now apparent in all networks. These networks multiplex a variety of communication services delivered to customers with high expectations, commanding flawless reliability, easy upgradability and scalability, as well as superior operational efficiency.

Boosting Capacity of POT Networks

Likewise, network service providers and network equipment manufacturers need to find the best approach to make this transition successful. They need to increase their packet transport capability without negatively impacting revenue-generating legacy products and services. This network evolution makes testing and qualification of fiber-optic cables and transport networks during installation and commissioning crucial.
