COLORADO SPRINGS, Colo. -- Fiber optic analyst firm ElectroniCast Consultants predicts the fiber-optic circulator market will be dominated by three-port devices for at least the next five years. A new study on the passive circulator market sees growth from close to $170 million in 2007 to $280 million in 2012.
Passive circulators are used in a variety of WDM and add-drop multiplexing applications ranging from metropolitan networks to ultra-long-haul optical transport. They transmit a signal from one port to another, while simultaneously transmitting a second signal from the second port to a third.
The new study sees a steady but very slow growth in four-port circulators, which constitute roughly 10 percent of the overall market, and very small inroads for advanced components of more than four ports. In 2007, the three-port device held 87.6 percent market share with a global consumption value of $148.9 million. That market share will decrease to 85.4 percent by 2012, when its consumption value will be $222.7 million, according to ElectroniCast.
