QSFP-40G-CSR4-RF

QSFP 4x10GBASE-SR TransceiverModule,MPO, 300M REMANUFACTURED

Inventory quantities are subject to availability and are not guaranteed until the order is placed.

The Cisco QSFP-40G-CSR4-RF is a professionally remanufactured 40GBASE-CSR4 QSFP+ transceiver module designed for short-reach 40 Gigabit Ethernet connectivity over multimode fiber. This hot-pluggable optical module uses four independent 10 Gbps channels (4x10G) with MPO/MTP connectors, delivering 40 Gbps aggregate bandwidth over OM3 multimode fiber up to 300 meters or OM4 multimode fiber up to 400 meters. The CSR4 (short-reach) specification makes it ideal for data center spine-leaf architectures, top-of-rack switching, and inter-rack connectivity where distances are under 400 meters.

This remanufactured QSFP+ module has been thoroughly tested and certified to meet Cisco's quality standards. Each unit undergoes comprehensive testing including optical power measurement, bit error rate testing, temperature cycle testing, and interoperability validation. The module features DOM (Digital Optical Monitoring) for real-time monitoring of temperature, voltage, laser bias current, transmit power, and receive power. Compatible with Cisco Nexus switches, Catalyst switches, ASR routers, and UCS fabric interconnects supporting QSFP+ interfaces. Low power consumption (under 3.5W) reduces operating costs and heat generation.

Key Features:
• 40 Gbps aggregate bandwidth
• 4x10G MPO/MTP interface
• OM3: 300m, OM4: 400m range
• Hot-pluggable QSFP+ form factor
• DOM support
• Compatible with Cisco infrastructure
• Low power consumption
• Cost-effective remanufactured solution

Perfect for data center spine-leaf networks, top-of-rack switching, server-to-switch connections, storage area networks, inter-rack connectivity, and any short-reach 40GbE deployment over multimode fiber. By choosing remanufactured Cisco optics, you're reducing electronic waste while ensuring your network infrastructure delivers the bandwidth, reliability, and monitoring capabilities your data center applications demand.
