The QSFP-40G-LR4 is a parallel 40Gbps Quad Small Form-factor Pluggable (QSFP+) optical module designed for high-density, high-speed networking environments. This Cisco compatible 40GBASE-LR4 QSFP+ module supports link lengths of up to 10 kilometers over standard Single-Mode Fiber (SMF, G.652) via a duplex LC connector. Operating on four coarse wavelength division multiplexing (CWDM) lanes, it integrates seamlessly into data centers, enterprise core networks, and service provider transport infrastructures. It complies fully with the QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 standards.
Q1: What is the main difference between Cisco QSFP-40G-LR4 and QSFP-40G-LR4-S?
A: The primary difference is protocol support. The standard QSFP-40G-LR4 supports both enterprise Ethernet networks and OTN (Optical Transport Network) OTU3 data rates, offering maximum versatility for service providers. Conversely, the QSFP-40G-LR4-S (S-Class) is designed strictly for enterprise Ethernet applications and lacks OTN support. For standard enterprise data centers, the S-Class version is a budget-friendly option, while the standard LR4 offers the broadest compatibility profile.
Q2: Can I break out a 40G QSFP-40G-LR4 port into four 10G SFP-10G-LR ports?
A: No, you cannot use a breakout cable (such as an MPO-to-4xLC duplex) with the QSFP-40G-LR4 module to split it into 4x 10G links. This is because the QSFP-40G-LR4 uses an internal MUX/DEMUX to combine 4 distinct CWDM wavelengths onto a single single-mode fiber pair. If your application specifically requires breaking out a 40G single-mode port into 4x 10G SFP+ links, you must use a QSFP-40G-PLR4 (Parallel LR4) module which utilizes an MPO/MTP connector.
Q3: How do you guarantee the compatibility and quality of your third-party Cisco transceivers?
A: At LonRise, quality assurance is our top priority. Every single Cisco compatible module goes through a rigorous data center simulation testing process. This includes structural hardware checks, distance/attenuation performance testing, and live verification on native Cisco Catalyst and Nexus switches. This ensures 100% host system recognition, fully functional DOM diagnostics, and zero bit errors.
Q4: What are your warranty terms and after-sales customer service policies?
A: We provide an industry-leading 3-year warranty and lifetime expert technical support on all optical transceiver modules. If a product experiences any hardware or compatibility issues within the warranty window, we provide expedited free replacement or repair services. Our global customer support team guarantees a response time of under 12 hours to assist with any network integration or troubleshooting needs.
