Tunable Laser Market Opportunities, Market Forecasts, and Market Strategies, 2006-2012

As networks are implemented for triple play, they become complex, driving the need for fast transport based on optics. Manufacturers of communications and computer equipment are increasingly value the ability to provide integrated solutions for both opto-electronic components and integrated circuits.
Tunable lasers address growing demands for capabilities to reconfigure networks remotely as broadband quality of service demands create the need for flexibility.
Integrated optical components include amplifiers, lasers, receivers, transmitters, and transceivers and transponders. Markets are growing in response to the need to have more efficient networks that are high speed and agile. Flexibility and re - configurability are aspects of optical based networks.
Market driving forces relate to the need for broadband, the use of the Internet to implement supply chain economies of scale, the ability to put together a network at less cost, and the increased capacity for communication systems provided by optical components.
Internet protocol architecture is significantly more efficient than circuit switched architecture. Circuit switches provide an end-to-end connection for voice traffic. This type of network architecture is very inefficient, tying up a line during the
silences and pauses of a voice conversation. (or laser).
A laser is the device that generates the modulated light signal and transmits it through the optical system. By turning the laser device on to represent a digital 1 and turning it off to represent a digital 0 digital processing is made possible. Each optical signal has its own wavelength or frequency.
Multiplexing is the technology of aggregating multiple wavelengths onto a single strand of fiber. This process is accomplished through the use of optical devices called wavelength division multiplexers (or WDMs). It is designed to increase the capacity of the optical network.
Widely tunable lasers help maximize existing network resources. The ability to dynamically provision bandwidth provides the ability to meet demands for Internet access. Widely tunable lasers move traffic from overcrowded channels to unused channels. They simplify the planning process. When a provider purchases a tunable laser, the widely tunable laser can cover the whole C-band and, in time, another will cover the L-band.
Aggregate demand for tunable lasers is related to the need for network managers to manage 100 distinct wavelengths. One widely tunable laser transmitter can be a spare for 100 wavelengths, meaning a carrier can rapidly restore transmission on the wavelength of any failed transmitter, fixed or tunable. Using widely tunable lasers throughout the network deliver reconfigurability and economy of scale.
Tunable lasers offer multiple wavelengths in the same laser device. Categorizations for tunable lasers relate to metro and long haul, narrowly tunable and widely tunable. Long haul lasers do not need to solve complexity, nor do they need to be complex. Long haul lasers are used in the long haul network to replace single channel lasers in the event of a malfunction.
The market for tunable lasers at $183 million in 2005 is expected to reach $3.1 billion in 2012 (See Figure 2-46 and Table 2-47). Market driving forces are the need for dynamic reconfiguration of core networks. In addition, physical layer support for packet switching means tunable lasers will be used to implement broadband for the Internet.
