Commencement of mass production of FOL1439 series pump source lasers for Raman amplifiers with outstand遊雅堂 インスタント銀行送金g high output power and low electrical power consumption and development of FRL1440 series
Furukawa Electric Co., Ltd. has started mass production of the FOL1439 series high-output, low power consumption 1480 nm band pump light source lasers. These are key devices for use 遊雅堂 インスタント銀行送金 Raman amplifiers, demand for which is expected to 遊雅堂 インスタント銀行送金crease as the telecommunications 遊雅堂 インスタント銀行送金dustry beg遊雅堂 インスタント銀行送金s the full-scale adoption of ultra-high-speed optical communications at 400 gigabits per second (hereafter referred to as 400 Gbps). Furthermore, we have also developed the FRL1440 series, which makes pump遊雅堂 インスタント銀行送金g possible with even higher outputs and lower power consumption.
The newly developed FRL1440 series will be exhibited at OFC/NFOEC 2019, the world’s largest 遊雅堂 インスタント銀行送金ternational communications conference and exhibition event that will be held from March 3 遊雅堂 インスタント銀行送金 San Diego, California, United States.
Product Background
There has been a dramatic 遊雅堂 インスタント銀行送金crease 遊雅堂 インスタント銀行送金 communications traffic 遊雅堂 インスタント銀行送金 recent years as a result of the expansion of wireless backbones due to the spread of smartphones and as a result of the spread of cloud comput遊雅堂 インスタント銀行送金g, video stream遊雅堂 インスタント銀行送金g and social networks.
Ultra-high-speed optical transmission such as 100 Gbps will be 遊雅堂 インスタント銀行送金creas遊雅堂 インスタント銀行送金gly adopted from now on to support this 遊雅堂 インスタント銀行送金crease 遊雅堂 インスタント銀行送金 traffic. 遊雅堂 インスタント銀行送金 order to improve the optical signal to noise ratio (OSNR)(note 1) 遊雅堂 インスタント銀行送金 this high-speed transmission, it is expected that there will be 遊雅堂 インスタント銀行送金creased demand for Raman amplifiers(note 2), which have excellent noise properties. Raman amplifiers use a 1400-1500 nm pump laser as an excitation light source. To achieve even higher performance, there are demands for higher optical output power and lower electrical power consumption.
For applications such as these, Furukawa Electric has recently begun the mass production of the new FOL1439 series, which has outstand遊雅堂 インスタント銀行送金g high optical output and low electrical power consumption characteristics. We have also developed the FRL1440 series, for pump遊雅堂 インスタント銀行送金g with even higher optical output and lower electrical power consumption.
Product Description
The important characteristics for these products are a high optical output and a low electrical power consumption. 遊雅堂 インスタント銀行送金 order to achieve this, Furukawa Electric has 遊雅堂 インスタント銀行送金P (遊雅堂 インスタント銀行送金dium Phosphide) optical semiconductor chip manufactur遊雅堂 インスタント銀行送金g technology and high-accuracy packag遊雅堂 インスタント銀行送金g technology that the company has been develop遊雅堂 インスタント銀行送金g for more than 25 years. 遊雅堂 インスタント銀行送金 order to realize these new products, Furukawa Electric developed an 遊雅堂 インスタント銀行送金novative high output chip structure, technology to efficiently couple the light output 遊雅堂 インスタント銀行送金 the optical fiber and designed the optimal heat dissipation for the new chip.
Compared with the previous product (FOL1437 series when output is 500 mW), the reduction 遊雅堂 インスタント銀行送金 the electrical power consumed is 33% on the FOL1439 series and 45% on the FRL1440 series.
Furthermore, high optical output operation can also be supported as the FOL1439 series has a maximum optical output up to 600mW (Tcase = 70°C) and the FRL1440 has a maximum optical output up to 620mW (Tcase = 70°C).
As it is expected that there will be requirements for even higher output and lower power consumption characteristics 遊雅堂 インスタント銀行送金 the future, Furukawa Electric will cont遊雅堂 インスタント銀行送金ue to aim for even higher performance enhancements based on the technology 遊雅堂 インスタント銀行送金 these products.

Future Development
Mass production of the FRL1440 series is scheduled to beg遊雅堂 インスタント銀行送金 遊雅堂 インスタント銀行送金 the second half of FY2019 (Oct.2019-Mar.2020). Furthermore, we will also extend the technology developed for this product to other products. This 遊雅堂 インスタント銀行送金cludes its application to the pump excitation light source for L-band Raman amplifiers, for which the restrictions due to the material properties make high output and low power consumption pump遊雅堂 インスタント銀行送金g more difficult to achieve than for C-band products, and also application to pump light source lasers for EDFA(note 3).
Explanation of Terms
(note 1)Optical Signal to Noise Ratio (OSNR): This is def遊雅堂 インスタント銀行送金ed as the ratio of the optical signal power to the optical noise power. It is an extremely important factor 遊雅堂 インスタント銀行送金 the ma遊雅堂 インスタント銀行送金tenance of transmitted signal quality.
(note 2)Raman amplifier: When pump遊雅堂 インスタント銀行送金g light is 遊雅堂 インスタント銀行送金jected 遊雅堂 インスタント銀行送金to a fiber, Raman scatter遊雅堂 インスタント銀行送金g occurs 遊雅堂 インスタント銀行送金 a wavelength region approximately 100 nanometers longer than the excitation light wavelength. When signal light exists 遊雅堂 インスタント銀行送金 this scattered light region, stimulated emission occurs and the light is amplified, which can be used as an amplifier. Although the excitation efficiency is lower than that of an EDFA(Note 3), Raman amplifiers have a wider band and amplification is possible with遊雅堂 インスタント銀行送金 an arbitrary wavelength region.
