Cisco QSFP-100G-B20U4-I Compatible 100GBASE-BX20-U QSFP28 BiDi 1280nm-TX/1310nm-RX 20km DOM Simplex LC/UPC SMF Optical Transceiver Module

The 100Gbps QSFP28 BIDI Optical Transceiver is designed for efficient short-range communication over single-mode fiber (SMF) up to 20 kilometers. Utilizing bi-directional optical signaling, it operates on a simplex LC connector and integrates a 4x25Gbps NRZ electrical interface. The module supports 100GBASE-LR BIDI and is fully compliant with QSFP28 MSA, IEEE 802.3cu, and SFF-8679 standards. Equipped with an EML laser and PIN receiver, it ensures robust and reliable performance for high-speed data transmission.

Operating with a single +3.3V power supply, the transceiver consumes a maximum power of 4.5W and supports operating temperatures ranging from 0°C to 70°C. Advanced digital diagnostic monitoring (DDM) enables real-time access to operating parameters like temperature, voltage, bias current, and optical power. With features like hardware TX disable and RX loss of signal detection, the QSFP28 BIDI transceiver offers enhanced diagnostics and compatibility for data center, telecom, and enterprise networking environments.
