The 40Gbps QSFP+ ZR4 Optical Transceiver is a high-performance module engineered for long-range data transmission over single-mode fiber (SMF) up to 80 kilometers. This transceiver uses a 4-channel MUX/DEMUX design, where each channel supports up to 11.2Gbps, achieving a combined bandwidth exceeding 40Gbps. Featuring LAN WDM technology, it integrates TOSA (Transmit Optical Subassembly) and ROSA (Receive Optical Subassembly) for enhanced signal integrity. The transceiver is compliant with 40G Ethernet IEEE802.3ba standards, QDR/DDR InfiniBand data rates, and QSFP MSA specifications, making it suitable for metro networks, data center interconnects, and switch-to-router applications.
Operating on a single +3.3V power supply with a maximum power consumption of 5W, the module ensures energy efficiency and reliable performance in commercial environments, with an operating temperature range of 0°C to 70°C. It features a duplex LC connector for optical interfaces and a 38-pin electrical interface for integration with host systems. Advanced diagnostics, including digital monitoring of temperature, voltage, bias current, and optical power, are accessible via a 2-wire serial interface. These capabilities, combined with its robust design and compliance with RoHS standards, make the QSFP+ ZR4 an essential component for high-speed, long-distance networking.
This hot-pluggable QSFP+ module multiplexes 4 × 10.3125 Gbps electrical lanes into 4 CWDM optical signals (1296–1310 nm), aggregated into a 40Gbps channel. It complies with IEEE 802.3ba 40GBASE-ZR4, QSFP+ MSA, and Infiniband QDR/DDR standards. Designed for SMF up to 80 km, it uses a duplex LC interface. The module operates on a single 3.3 V supply, dissipating up to 3.5 W, with built-in digital diagnostics. Operating case temperature range is 0 °C to +70 °C.
