100GE CWDM4 2km QSFP28光模块 - 北亿纤通|F-tone Networks-全球光芯片光器件光模块光通信系统产品领导者!

Description
The F-tone Networks 100GE CWDM4 2km QSFP28 optical transceiver (FTQ2-HG-CWDM4-02xx) is designed for use in 100-Gigabit Ethernet links up to 2km on Single Mode Fiber (SMF). It is compliant with the QSFP28 MSA, CWDM4 MSA and relevant portions of IEEE 802.3bm. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA. It converts 4 input channels of 25.78125Gb/s electrical data to 4 channels of CWDM optical signals and then multiplexes them into a single channel for 103.125Gb/s optical transmission. Reversely on the receiver side, the module de-multiplexes a 103.125Gb/s optical input into 4 channels of CWDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as members of the CWDM wavelength grid defined in CWDM4 MSA.
