Frequently Asked Questions
What is a 100G SR4 optical module used for?
The 100G SR4 is designed for short-range, high-bandwidth connections in data centers and enterprise networks. It supports 100 Gbps connectivity over multi-mode fiber up to 100 meters, making it perfect for inter-switch links, server-to-storage connections, and campus backbone deployments.
Is the Ubiquiti QSFP28 transceiver compatible with my network switch?
Yes, this QSFP28 module is compatible with any network switch featuring QSFP28 ports. It's designed for hot-plug operation, allowing you to install or replace it without powering down your equipment. Verify your switch supports 100G SR4 specifications for optimal performance.
What's the difference between SR4 and LR4 optical modules?
SR4 (short-range) modules like this one support up to 100 meters over multi-mode fiber, ideal for data center environments. LR4 (long-range) modules support longer distances over single-mode fiber. Choose SR4 for dense, high-speed intra-data-center connectivity.
Can I use this multi-mode optical module with single-mode fiber?
No, this module is specifically designed for multi-mode fiber (OM3/OM4). Using it with single-mode fiber will result in poor performance or connection failure. Always match your transceiver type to your fiber infrastructure.
