ANAHEIM, Calif. -- Furukawa Electric Company, Ltd. has developed a micro Integrable Tunable Laser Assembly (ITLA), a key component in ultrahigh-speed optical digital coherent transmission devices operating at 100 gigabits per second (Gbps). This transmission device is now being introduced globally with initial sampling of the micro ITLA. In addition to meeting the industries' demand for much lower power consumption and high optical output, Furukawa has also developed a new wave length tunable laser chip that enables an additional 20% reduction in power consumption. When used in combination with the micro ITLA, it further reduces power consumption by 40% against conventional products and nearly doubles the optical output when compared with micro ITLA. These benefits along with the acceptance of the Optical Internetworking Forum (OIF) to standardize the ITLA specification make the micro ITLAs an attractive choice for optical communication devices. The new wave length tunable laser chips are planned to be mounted on the micro ITLA devices beginning in early 2014.
Presently, global network traffic continues to grow at a phenomenal rate in both terrestrial and wireless networks. With smartphones now a ubiquitous tool for consumers and business users, acceptance of cloud computing, data center connectivity and mass video distribution, the telecommunications industry is presently accelerating the deployment of 100Gbps transmission systems for high capacity. The industry has converged on optical digital coherent technology in transmission systems, which involves the use of optical phases (wave conditions) resistant to signal deterioration and impervious to the effects of noise.
Furukawa has already commercialized high-output and narrow-line-width ITLAs that exhibit excellent properties for signal lights from the optical digital coherent system (Note 1) and for local oscillator (Note 2). Since the industry continues to demand higher capacity, the specifications for small and low power-consumption ITLAs have now been accepted and standardized by the OIF (Note 3).
