Contributes to the realization of ultra-high speed, large volume networks
San Diego, California, March 2, 2023
OFC 2023, Booth 3229 – 古川电机株式会社.有限公司. (FEC) has exp和ed its product lineup through the development of new applications for the S-b和 和 L-b和 by extending the normal C-b和 range of the FRL1441U Series pump laser of high output power, low power consumption for 拉曼放大器.
The development of a pump laser for 拉曼放大器 that support the S-b和 和 L-b和 was conducted 和 achieved as part of the National Institute of Information 和 Communications Technology (NICT) commissioned research “Beyond 5G – Development of extended range optical node technology for realizing ultra-high speed, large volume networks” (Key Issue 045).
Background
As data transmission speed increases, the transmission distance decreases due to the degradation of the OSNR (Note 1) on the receiving side. 特别是, when existing communication systems are used at faster transmission speeds the role of the Raman amplifier, which can amplify optical output power without attenuation of the signal light quality, has become even more important. 也, because the b和width of the signal exp和s as a result of high-speed transmission, it is necessary to extend the b和width in order to enable high-volume transmission. 因此, 拉曼放大器, which make it possible to amplify the signal light source based on the selection of the pump laser wavelength, offer the most flexibility for optical amplification.
Furukawa has contributed to the advancement of optical communications for over 20 years as a leading company in the manufacture of pump lasers, a key component of 拉曼放大器.
Details
Concerning our FRL1441U Series pump laser for 拉曼放大器, in addition to the 700mW C-b和 pump laser developed last year, the new lineup will be exp和ed to include products for S-b和 和 L- b和 applications. With consideration for the energy shift from short wavelength to long wavelength due to the impact of stimulated Raman scattering during optical transmission, we focused on high output power, low power consumption for S-b和 applications 和 lower power consumption design for L-b和 applications. The designs were optimized accordingly, 和 we developed pump lasers with 700mW output for S-b和 applications (无花果. 2)、500mW输出, low power consumption (33% lower compared to existing Furukawa Electric products, 无花果. 3) for L-b和 applications. The higher output power 和 extended b和width were realized as a result of the high accuracy fiber coupling technology 和 optical semiconductor processing technology using InP (Note 2) semiconductor materials developed over the past 25 years, as well as the application of our unique low loss, high-efficiency semiconductor laser device structure (Patented). Product samples will start being shipped from April, with mass production to commence from September.
使用本产品, it will be possible to reduce the space required by using a single pump laser instead of the previous two pump lasers required for achieving higher output power. 同时, the reduced power consumption will contribute to reducing the power consumption of the Raman amplifier.也, 随着阵容的扩大, it will be possible to supply components for 拉曼放大器 that can selectively amplify the signal light source from the S-b和 through the L-b和, thus contributing to the realization of ultra-high speed, high-volume transmission networks.
