The QSFP-100G-BD40-0409 and QSFP-100G-BD40-0904 are a paired set of bidirectional (BD) QSFP28 transceivers, engineered for 100Gbps full-duplex transmission over a single 9/125μm single-mode fiber up to 40km, leveraging wavelength division to optimize fiber usage. The 0409 model transmits at 1304nm and receives at 1309nm, while the 0904 model reverses this (1309nm Tx / 1304nm Rx), forming a complementary pair critical for metro networks, data center interconnects, and long-haul 100G links. Both feature hot-swappable QSFP28 form factors, integrated DDM/DOM for real-time monitoring, and compliance with IEEE standards, ensuring reliable high-speed connectivity.
Share:
Bidirectional Pairing: Operate as a matched set, enabling 100Gbps full-duplex communication over a single fiber via wavelength division multiplexing (WDM), cutting fiber resource requirements by 50% compared to dual-fiber solutions.
Wavelength Complementarity: 0409 (1304nm Tx / 1309nm Rx) and 0904 (1309nm Tx / 1304nm Rx) use closely spaced wavelengths to avoid interference, ensuring stable 40km transmission.
Practical Performance: Supports 40km reach, integrates DDM/DOM for tracking temperature, voltage, and optical power, and features hot-swappable design for easy maintenance, ideal for 100G metro or long-haul interconnections.
