The QSFP-100G-BD20-3327 and QSFP-100G-BD20-2733 are a paired set of bidirectional (BD) QSFP28 transceivers, designed for 100Gbps single-fiber transmission over 20km of single-mode fiber, with wavelength division to enable bidirectional data flow. Specifically, the 3327 model transmits at 1331nm and receives at 1271nm, while the 2733 model reverses this (1271nm Tx / 1331nm Rx), forming a complementary pair for point-to-point long-haul links in metro networks or data center interconnects. Both feature hot-swappable QSFP28 form factors, integrated DDM/DOM for real-time monitoring, and compliance with industry standards, ensuring seamless integration into high-speed network infrastructures.

Bidirectional Pair Design: The two transceivers operate as a matched set, using wavelength-division multiplexing (WDM) to enable 100Gbps full-duplex transmission over a single 9/125μm single-mode fiber, reducing fiber resource usage by 50%.
Wavelength Complementarity: 3327 (1331nm Tx / 1271nm Rx) and 2733 (1271nm Tx / 1331nm Rx) form a cross-wavelength pair, ensuring unidirectional signals on the same fiber do not interfere.
Practical Performance: Supports 20km reach, integrates DDM/DOM for monitoring temperature, voltage, and optical power, and features hot-swappable design for easy maintenance, suitable for 100G metro links or data center interconnections.
