LOUISVILLE, Colo. -- Zolo Technologies, Inc., a provider of high-performance, low-cost DWDM devices to the optical telecommunications systems market, today announced that it is delivering passively thermally compensated (PTC) multiplexers and demultiplexers that offer less than half the thermal drift of other free-space-diffraction-grating devices—and less than many actively thermally compensated arrayed-waveguide-grating (AWG) devices. Zolo’s passive Zmux™ products yield wavelength drift performance of 0.43 pm/oC over the –5 to 70 oC operating range. This low thermal drift is achieved while maintaining other high-performance specifications. The end result to customers is enhanced design flexibility, lower maintenance costs, and a lower total cost of ownership (TCO) because optical passband is more consistent and stable. Systems designers can use this guaranteed passband to enhance system reliability and reduce system costs, and ease-of-design is further enhanced because there are no electronic power components to design around. “DWDM systems and subsystems companies benefit from Zmux’ outstanding performance because optical network designs can be simplified and the cost of system ownership is lowered dramatically,” says Ed Barbera, president and CEO of Zolo Technologies. “It’s not enough that DWDM devices be low in cost. They must also offer high performance and provide telecommunications end users with a low TCO that helps them save money over the life of a system’s operation.”Zolo Technologies Inc.
