The 40Gbps QSFP+ PSM4 Optical Transceiver is a high-performance module designed for parallel optical data transmission over single-mode fiber (SMF) up to 10 kilometers. It features four independent transmit and receive channels, each supporting data rates of up to 10Gbps for an aggregate bandwidth of 40Gbps. The module utilizes an MTP/MPO connector for seamless integration with optical fiber ribbon cables, ensuring proper alignment for efficient signal transmission. It complies with QSFP+ MSA standards and is ideal for applications such as 40G Ethernet, Infiniband QDR/DDR/SDR, and data center networking.
Operating on a single +3.3V power supply with a maximum power consumption of 3.5W, the transceiver is designed for reliability in diverse conditions, with an operating temperature range of 0°C to 70°C. It includes advanced digital diagnostics for real-time monitoring of parameters like temperature, voltage, and optical power. The module’s integrated design ensures compatibility with a variety of host systems while supporting key control signals like reset, low-power mode, and module presence. Its robust construction and compliance with RoHS make it an efficient and environmentally friendly choice for high-speed data networks.
This full-duplex optical transceiver provides four parallel transmit and receive channels, each operating up to 11.2 Gbps, for an aggregated 40Gbps link. It complies with QSFP+ MSA and IEEE 802.3ba 40GBASE-PSM4 standards, using ribbon fiber with MPO/MTP connectors. The module supports 10 km over G.652 SMF, features DDMI via I²C, and is designed for harsh environments with EMI protection. Power consumption is ≤3.5 W on a single 3.3 V supply, with an operating case temperature of 0 °C to +70 °C.
