Most consumers are no longer satisfied with surfing the Web, downloading a few songs, sending and receiving a few photographs, or watching streaming video at current picture quality levels. The Fiber to the Home (FTTH) Council explains it best: "The world is moving toward vastly higher bandwidth applications."
Here are some reasons why:
Here are some reasons why:
- Companies such as Netflix, Amazon and Wal Mart offer feature-length movies for download
- More people want to upload their home movies to e-mails or Web pages
- Consumer electronics companies offer devices that connect TV to the Internet
- High-definition video is fast becoming state-of-the-art
- More companies are offering "software as service," which means consumers subscribe to applications on the Internet instead of installing them on their computer
Consumer bandwidth is projected to grow for years to come.
For network operators to stay competitive in this market, it is important to add fiber-to-the-home (FTTH). Where do you start? By comparing architectures. All FTTH architectures require an aggregation device in the CO (Optical Line Terminal or OLT) and an optical electric converter (Optical Network Terminal or ONT) at the home. The architectures differ in what is installed between the CO and the house.
To make it easier for you, we've researched several architectures for you. This guide, "At-a-Glance Comparison of FTTH Architectures," provides a comparative analysis of FTTH solutions, including the advantages, disadvantages and costs of:
· Point-to-Point
· Active Ethernet
· PONs
· BPON
· GPON
· EPON
· WDM PON
· RFoG
