Features
The Cisco QSFP40G BiDi Short-reach Transceiver is a high-performance optical transceiver designed for data centers and enterprise networking environments. Developed by Cisco, a leader in network solutions, this module is crafted to support fast, reliable connections over multi-mode fiber (MMF). The compact module measures 13.5 x 18.4 x 72.4 mm, making it ideal for high-density networking setups where space efficiency is critical.
Wavelength and Optical Characteristics
This transceiver utilizes a bidirectional technology that operates across a wavelength range of 832 to 918 nanometers. By enabling both the transmit and receive functions within this spectrum, the BiDi module dramatically reduces the amount of fiber infrastructure needed for 40G connections. The module supports different modal bandwidths depending on the fiber type-500 MHz-km for OM2, 2000 MHz-km for OM3, and an impressive 4700 MHz-km for OM4 fibers-ensuring reliable performance over varying distances.
Cable Distance and Power Specifications
The Cisco QSFP40G BiDi transceiver is optimized for short-reach applications, supporting maximum cable distances of 30 meters on OM2, 100 meters on OM3, and up to 150 meters on OM4 multimode fiber. Power consumption is maintained at an efficient 3.5 watts, helping to minimize heat dissipation and energy costs in large-scale deployments. The device features transmit powers from -4 dBm up to +5 dBm per lane, and receive sensitivity from -6 dBm to +5 dBm per lane, ensuring robust signal integrity in complex environments.
Operational Temperatures and Standards Compliance
Engineered for reliability, the transceiver operates within commercial temperature ranges from +10°C to +70°C (50°F to 158°F) and can be stored at temperatures as low as -40°C and as high as 85°C (-40°F to 185°F). Compliance with industry standards is extensive, including GR-20-CORE, GR-326-CORE, GR-1435-CORE, various IEEE standards (such as 802.3ba and 802.3ae), as well as QSFP+ and SFP+ MSA specifications. RoHS 6 compliance further guarantees that the device meets current environmental and health safety regulations.
Safety and Regulatory Certifications
For added assurance in demanding installations, the cable jacket of compatible QSFP copper modules complies with the UL E116441 safety standard, and the copper cables themselves meet the requirements of the ELV (End-of-life Vehicles) directive. These certifications, combined with Cisco's rigorous testing protocols, ensure the transceiver delivers both safe operation and exceptional performance across a variety of networking scenarios.
