The 100 Gb Ethernet signal is transmitted over four wavelengths. Four wavelength multiplexing and demultiplexing are managed within the device. BOX+FPC+PCBA standalone design provides excellent reliability, air tightness and heat dissipation performance. The transceiver complies with IEEE 802.3ba standard. Digital diagnostics are also available via the I2C interface specified by the QSFP28 MSA to allow access to real-time operational parameters. With these features, This easy-to-install hot-swappable transceiver is suitable for a variety of applications, such as 100G telecom connectivity, data centers, high-performance computing networks, and enterprise core and distributed layer applications.
