Triple Play

As a solution to the user pressures, the favored service offering for broadband today, whether DSL cable or FTTx is a standard mix of traffic types referred to as triple play. The three traffic components are:

• bidirectional voice bit streams
• video (unidirectional and usually analog up to now)
• bidirectional high-speed data

Today it may be difficult to imagine why this categorization does not cover every foreseeable contingency, but if new classes or subclasses of traffic evolve, the huge bandwidth and the protocol and format transparency of fiber will accommodate them gracefully. It seems likely that the first addition to the present mix will be to make the video component bidirectional.

Until now, DSL cable still dominanted the service but in the future FTTH or fiber to the home will take place and actually in certain places like US, Japan and Korea was already deploys FTTH or fiber to the home.
