Frequently Asked Questions
What is a 40GBASE-LR4 QSFP+ transceiver used for?
A 40GBASE-LR4 QSFP+ transceiver is used to establish 40 Gigabit Ethernet connections over long distances (up to 10 km) using single-mode fiber. It's commonly deployed in data center interconnects, campus backbone networks, and high-performance computing environments where extended reach and high bandwidth are required.
Is this QSFP+ module compatible with Fortinet FortiGate appliances?
Yes. This ENET 40GBASE-LR4 QSFP+ module is specifically engineered for Fortinet FortiGate security appliances and other compatible networking platforms. Verify your device's QSFP+ port specifications and supported transceiver list before installation.
What does Digital Optical Monitoring (DOM) provide?
DOM functionality enables real-time monitoring of optical signal strength, module temperature, laser bias current, and other critical parameters. This allows network administrators to proactively detect signal degradation, thermal issues, and potential failures before they impact network performance.
Why is TAA compliance important?
TAA (Trade Agreements Act) compliance ensures the product meets U.S. government procurement standards. Organizations subject to federal contracting requirements must use TAA-compliant components. This 40GBASE-LR4 QSFP+ transceiver meets these standards, making it suitable for government and regulated enterprise deployments.
