QSFP+ is a compact transceiver emerging as the standard for 40GbE. Its technology for longer-reach single modes finds many applications beyond 100m such as communication equipment used for data storage, networking devices for data centers, and enterprise networking where high-density power-saving systems are required.
The ROSA satisfies the IEEE 802.3ba requirements for the 40Gb/s optical receiver. The 40GbE performance is based on transmitting and receiving four different wavelengths at 10Gb/s. This compact size ROSA includes four high-speed PIN photodiodes, four transimpedance amplifiers, and an optical demultiplexer which consists of specially designed low insertion loss filters and mirrors. The device supports extremely high receiver sensitivity of -16dBm.
By applying this superior technology to higher bit rate devices, Sumitomo Electric will offer a 4-channel ROSA for 100GbE.
