100GBASE-LR4 10km 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 100GBASE-LR4 10km QSFP28 optical transceiver (FTQ2-HG-LR4-10xx) is designed for use in 100-Gigabit Ethernet links up to 10km on Single Mode Fiber (SMF). It is compliant with the QSFP28 MSA, IEEE 802.3ba 100GBASE-LR4 and IEEE 802.3bm CAUI-4. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA. It converts 4 input channels of 25.78125Gb/s electrical data to 4 channels of LAN-WDM 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 LAN-WDM optical signals and then converts them to 4 output channels of electrical data. The central wavelengths of the 4 LAN-WDM channels are 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm as members of the LAN-WDM wavelength grid defined in IEEE 802.3ba.

See the figure below.
The receiver shall be able to tolerate, without damage, continuous exposure to a modulated optical input signal having this power level on one lane. The receiver does not have to operate correctly at this input power.
Measured with conformance test signal at receiver input for BER =1×10^-12.
Vertical eye closure penalty and stressed eye jitter are test conditions for measuring stressed receiver sensitivity. They are not characteristics of the receiver.
