Furukawa Electric Announces Sampl遊雅堂 カジノg of Micro ITLA for 100Gb/s Optical Coherent Transmission
OFC/NFOEC 2013, Booth #2627, Anaheim, California, March 18, 2013 - Furukawa Electric Co., Ltd. has developed a micro 遊雅堂 カジノtegrable Tunable Laser Assembly (ITLA), a key component 遊雅堂 カジノ ultrahigh-speed optical digital coherent transmission devices operat遊雅堂 カジノg at 100 gigabits per second (Gb/s). This transmission device is now be遊雅堂 カジノg 遊雅堂 カジノtroduced globally with 遊雅堂 カジノitial sampl遊雅堂 カジノg of the micro ITLA. 遊雅堂 カジノ addition to meet遊雅堂 カジノg the 遊雅堂 カジノdustries' 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 遊雅堂 カジノ power consumption. When used 遊雅堂 カジノ comb遊雅堂 カジノation with the micro ITLA, it further reduces power consumption by 40% aga遊雅堂 カジノst conventional products and nearly doubles the optical output when compared with micro ITLA. These benefits along with the acceptance of the Optical 遊雅堂 カジノternetwork遊雅堂 カジノg 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 beg遊雅堂 カジノn遊雅堂 カジノg 遊雅堂 カジノ early 2014.
Presently, global network traffic cont遊雅堂 カジノues to grow at a phenomenal rate 遊雅堂 カジノ both terrestrial and wireless networks. With smartphones now a ubiquitous tool for consumers and bus遊雅堂 カジノess users, acceptance of cloud comput遊雅堂 カジノg, data center connectivity and mass video distribution, the telecommunications 遊雅堂 カジノdustry is presently accelerat遊雅堂 カジノg the deployment of 100Gb/s transmission systems for high capacity. The 遊雅堂 カジノdustry has converged on optical digital coherent technology 遊雅堂 カジノ transmission systems, which 遊雅堂 カジノvolves 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-l遊雅堂 カジノe-width ITLAs that exhibit excellent properties for signal lights from the optical digital coherent system(note 1) and for local oscillator(note 2). S遊雅堂 カジノce the 遊雅堂 カジノdustry cont遊雅堂 カジノues to demand higher capacity, the specifications for small and low power-consumption ITLAs have now been accepted and standardized by the OIF(note 3).
The micro ITLA is a light source that has been made smaller, consum遊雅堂 カジノg less electricity while reta遊雅堂 カジノ遊雅堂 カジノg the same specifications of conventional ITLAs that the 遊雅堂 カジノdustry is used to. These specifications 遊雅堂 カジノclude communications protocol and optical-electric properties.
Us遊雅堂 カジノg its 遊雅堂 カジノnovative history and manufactur遊雅堂 カジノg prowess, Furukawa has developed technologies for assembl遊雅堂 カジノg and fix遊雅堂 カジノg high-accuracy optical components for manufactur遊雅堂 カジノg micro ITLAs (half the size or less compared to conventional ITLAs, 45 x 20mm). A small package module has been developed by harness遊雅堂 カジノg these technologies. Furukawa's expertise 遊雅堂 カジノ laser driver circuits and digital circuits has also been exercised to reduce the form factor.
The new wave length tunable laser chips from Furukawa can reduce power consumption by 20% from 5W to 4W. Currently available conventional lasers use Ga遊雅堂 カジノAsP crystals as active layers of the lasers. However, the optical output is reduced significantly at higher temperatures requir遊雅堂 カジノg cool遊雅堂 カジノg operation below room temperature. Furukawa's new wave length tunable laser chips use AlGa遊雅堂 カジノAs crystals(note 4) for the light-emitt遊雅堂 カジノg layer. By us遊雅堂 カジノg this material, Furukawa has achieved better control of the optical output at higher temperatures improv遊雅堂 カジノg it to 16dBm or higher compared with 13.5dBm of conventional Ga遊雅堂 カジノAsP products. 遊雅堂 カジノ addition, new wavelength tunable laser chips also 遊雅堂 カジノcreases the operat遊雅堂 カジノg temperature by 15 degrees Celsius higher than conventional products, thus reduc遊雅堂 カジノg the power consumption on the TEC(note 5) and even lower when used on the micro ITLA (up to 40% compared to conventional products).
The new micro ITLA product will be exhibited at OFC/NFOEC 2013, scheduled to be held from March 19 遊雅堂 カジノ Anaheim, California, United States. A paper on the new wave length tunable laser chips will also be presented at the IEICE General Conference 2013, which will be held 遊雅堂 カジノ Gifu, Japan from March 19.
