100GBASE-BX80 QSFP28 Bi-Directional Optical Transceiver
(Single-Mode Fiber, LAN-WDM BiDi, 80 km, LC, DOM)
The 100GBASE-BX80 QSFP28 Bi-Directional optical transceiver is designed to deliver 100 Gb/s Ethernet throughput over single-mode fiber (SMF) with a transmission reach of up to 80 km using LAN-WDM wavelengths.
The module operates in a bi-directional configuration over a single fiber, transmitting and receiving on complementary wavelength sets. It uses four LAN-WDM wavelengths per direction, enabling efficient fiber utilization while maintaining long-reach performance.
This transceiver must be deployed in pairs with a corresponding module using complementary transmit and receive wavelengths. It supports hot-swappable operation and provides Digital Optical Monitoring (DOM/DDM) via an I²C interface in accordance with the QSFP28 MSA, allowing real-time access to operational parameters.
The 100G BX80 BiDi transceiver is suitable for 100G Ethernet, data center interconnect (DCI), and storage area network (SAN) applications requiring long-distance, single-fiber connectivity.
