Sumitomo Electric Industries, a cutting-edge optical solution provider, has reported the expansion of its optical device series with the launch of a 4-channel ROSA with optical demultiplexer for 40 Gb/s QSFP+ LR4.
QSFP+ is a smaller footprint transceiver, which is turning out to be the benchmark for 40 GbE. The transceiver’s longer-reach single mode technology holds potential in a variety of applications further than 100 m, including communication equipment utilized for networking devices for data centers, data storage, and enterprise networking that requires high-density power-saving systems.
The ROSA fulfills the IEEE 802.3ba prerequisites for the 40 Gb/s optical receiver. The 40 GbE performance is relied on the transmission and receipt of four different wavelengths at 10 Gb/s. This smaller footprint ROSA comprises an optical demultiplexer, four transimpedance amplifiers and four high-speed PIN photodiodes. The optical demultiplexer features specially developed low insertion loss filters and mirrors. The device provides support to very high receiver sensitivity of the order of -16 dBm. Sumitomo Electric will provide a 4-channel ROSA for 100 GbE through the application of this optical device to higher bit rate devices.
Sumitomo Electric Industries manufactures a variety of products ranging from optical fibers, components and cables to automotive parts and electronic devices. The company has turned out be a pioneer in information and communications by applying proven research and diversification strategies.
