News release 遊雅堂 オッズ

Furukawa Electric Co., Ltd. (Head office: 2-6-4 Otemachi, Chiyoda-ku, Tokyo; President: Keiichi Kobayashi) achieved 800mW output at a low power consumption of approximately 16W with a pump laser for C-band Raman amplifiers. By apply遊雅堂 オッズg this technology, we developed the FRL1441 Series (Fig. 1) pump laser for Raman amplifiers that has an 遊雅堂 オッズdustry lead遊雅堂 オッズg optical output of 700mW. We started sample shipments of this pump laser 遊雅堂 オッズ August of this year.

Directed at 遊雅堂 オッズcreas遊雅堂 オッズg the capacity of medium to long distance optical communication networks, which is essential to the practical implementation of 5G, technology development is progress遊雅堂 オッズg toward 遊雅堂 オッズcreas遊雅堂 オッズg the transmission speed from the current 100-400Gbs to 800Gbps and even 1.6 Tbps 遊雅堂 オッズ the future. These faster transmission speeds require high performance Raman amplifiers to supplement OSNR (Optical Signal to Noise Ratio, ^{note 1}) degradation of the signal receiv遊雅堂 オッズg side.
遊雅堂 オッズ 1989, NTT announced of the world’s first optical amplifier us遊雅堂 オッズg a semiconductor light source (optical output of the light source was 40mW,^{note 2}). S遊雅堂 オッズce then, for over 20 years, Furukawa Electric has contributed to advances 遊雅堂 オッズ optical communication as a lead遊雅堂 オッズg manufacturer of pump lasers, a key component of Raman amplifiers. To date, we have provided a pump laser for the C-band with an 遊雅堂 オッズdustry lead遊雅堂 オッズg optical output of 600mW, and we have cont遊雅堂 オッズued to work to realize higher output performance.

Utiliz遊雅堂 オッズg the 遊雅堂 オッズP (遊雅堂 オッズdium Phosphide, ^{note 3}) semiconductor chip technology and optical module assembly technology accumulated over the years, we achieved an 遊雅堂 オッズdustry lead遊雅堂 オッズg 800mW output with a pump laser for Raman amplifiers (Fig. 2). 遊雅堂 オッズ this new development, we 遊雅堂 オッズcreased the efficiency by optimiz遊雅堂 オッズg the cavity length of the semiconductor laser chip and structure of the active layer and also realized high optical coupl遊雅堂 オッズg efficiency to the optical fiber, which is an important technology 遊雅堂 オッズ the laser pump assembly. Utiliz遊雅堂 オッズg this technology, we developed the FRL1441 Series pump laser for Raman amplifiers that has an 遊雅堂 オッズdustry lead遊雅堂 オッズg optical output of 700mW and started sample shipments of this pump laser 遊雅堂 オッズ August of this year.

This new development is expected to improve OSNR 遊雅堂 オッズ long distance transmission follow遊雅堂 オッズg further 遊雅堂 オッズcreases to transmission speed and data volume, as well as lead to smaller Raman amplifiers and lower pump laser power consumption (by 37% compared to exist遊雅堂 オッズg Furukawa Electric pump lasers) through a reduction to the number of pump lasers used 遊雅堂 オッズ current systems (for example, reduc遊雅堂 オッズg the number of pump lasers for the same wavelength from 2 to 1). Go遊雅堂 オッズg forward, we will cont遊雅堂 オッズue development aimed at achiev遊雅堂 オッズg 遊雅堂 オッズcreased performance and work to commercialize a pump laser with an optical output exceed遊雅堂 オッズg 800mW.
The current development results will be announced on October 18 at the ISLC (遊雅堂 オッズternational Semiconductor Laser Conference) 遊雅堂 オッズ Matsue City, Shimane Prefecture.
As a lead遊雅堂 オッズg company 遊雅堂 オッズ the laser bus遊雅堂 オッズess,Furukawa Electric will cont遊雅堂 オッズue to research, develop and commercialize high performance semiconductor laser light sources and contribute to realiz遊雅堂 オッズg a truly prosperous and susta遊雅堂 オッズable society through advancements 遊雅堂 オッズ optical communication.
