The 100G BIDI QSFP28 optical transceiver (also called a 100G QSFP28 BIDI module or 100G QSFP28 single fiber transceiver) is a high-performance optical module that sends and receives 100Gigabit Ethernet (100GbE) traffic over a single strand of single-mode fiber (SMF). Using bidirectional Wavelength Division Multiplexing (WDM), each module transmits and receives on different wavelengths (for example, 1271 nm and 1331 nm for a 10 km link). This innovative design doubles fiber capacity and cuts cabling costs by about 50% compared to traditional dual-fiber QSFP28 transceivers. Despite using only one fiber strand with a simple LC connector, a 100G BIDI QSFP28 runs at full…
