The 100Gbps QSFP28 BIDI ER Transceiver is a high-performance optical module designed for long-distance communication over single-mode fiber (SMF) up to 40 kilometers. Supporting 100GBASE-ER BIDI with a lane signaling rate of 106.25Gbps using PAM4 modulation, the module features an EML laser transmitter and an APD receiver for robust data transmission. With a 4×25.78Gbps NRZ electrical interface and a simplex LC connector, it ensures efficient and reliable high-speed data transfer. The transceiver adheres to QSFP28 MSA, IEEE 802.3cu, SFF-8636, and SFF-8679 standards, making it ideal for high-performance networking applications.
Operating with a single +3.3V power supply and a maximum power consumption of 4.5W, the module functions within a case temperature range of 0°C to 70°C. Advanced digital diagnostic monitoring provides real-time feedback on temperature, voltage, bias current, and optical power. Its compliance with EU Directive 2015/863/EU and RoHS ensures environmentally friendly operation. The QSFP28 BIDI ER Transceiver is a reliable choice for long-range, high-speed communication in data centers and enterprise networks.
The CT-QSFP28-BX-40U and CT-QSFP28-BX-40D are high-performance BiDi QSFP28 modules designed for long-reach single-fiber transmission. Each module provides a 100 Gb/s PAM4 optical channel by multiplexing 4×25 Gb/s electrical lanes into one optical signal. The BX-40U transmits at 1304.58 nm and receives at 1309.14 nm, while the BX-40D operates with the reverse wavelengths. Both support up to 40 km over G.652 SMF, operate on a single +3.3 V power supply, and consume ≤ 4.5 W.
