Product Overview
QSFP-40GE-LR4 compatible 40GBASE-LR4 QSFP+ optical transceiver module (single-mode fiber, 1310nm, 10km, LC, DDM)
This 40G QSFP+ transceiver module, compatible with Cisco QSFP-40G-LR4, utilizes an LC duplex connector and achieves link transmission up to a maximum distance of 10 kilometers over OS2 single-mode fiber (SMF). The module is compatible with Cisco QSFP-40GE-LR4 and has been verified to interoperate with Cisco original switches, including the Catalyst 4500/8500/9800 and Nexus 3000/5000/6000/7000/7700/9200/9300/9500 series. This 40G optical transceiver is equipped with bidirectional 4-channel QSFP+ connectors, each supporting a data rate of 10 Gbps, achieving a total bandwidth of up to 40 Gbps. Additionally, this QSFP 40G fiber optic transceiver supports DOM/DDM (Digital Diagnostic Monitoring) functions, enabling real-time monitoring of operating parameters.
The 40GBASE-LR4 QSFP+ module produced by AndXe complies with the QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 specifications. Furthermore, this QSFP LR4 optical module has been tested on host devices, ensuring full compatibility with Cisco devices such as data center switches, enterprise routers, and server network interface cards (NICs). This third-party 40G SFP module is affordable and serves as an ideal replacement for the Cisco QSFP-40GE-LR4 QSFP+ 40G transceiver, providing a cost-effective and compatible solution for high-performance 40G connectivity.
The LR4 40G QSFP optical module is suitable for 40 Gigabit Ethernet (40GbE) fiber optic connections and is an ideal choice for high-performance and long-distance applications in data centers, enterprise core and distribution layers, campus networks, metropolitan area networks, and more.
