Frequently Asked Questions
What is 100GBASE-LR4 and how does it differ from other 100G standards?
100GBASE-LR4 is a long-reach variant of 100 Gigabit Ethernet that uses wavelength-division multiplexing over four lanes on single-mode fiber. Unlike 100GBASE-SR4 (short-reach, multimode), the LR4 standard supports distances up to 10 km, making it ideal for campus backbones and metro-area networks where extended reach is required without the cost of additional repeaters.
Is the ENET MA-QSFP-100G-LR4-ENC compatible with my existing network equipment?
Yes, the QSFP28 form factor and 100GBASE-LR4 standard ensure broad compatibility with modern data center switches, routers, and network interface cards from leading vendors. Verify your equipment supports QSFP28 slots and 100GBASE-LR4 transceivers. The duplex LC connector is the industry standard for this transceiver class.
What fiber type should I use with this 100GBASE-LR4 transceiver?
This transceiver is designed exclusively for single-mode fiber (SMF), typically OS2 grade with a 9-micron core. Single-mode fiber enables the extended 10 km reach by minimizing modal dispersion. Ensure your fiber plant meets ITU-T G.652 or equivalent standards for optimal performance and compliance.
Can I use this transceiver in hot-swap environments?
Yes, the QSFP28 form factor supports hot-swappable operation, allowing you to install or replace the transceiver without powering down your equipment. This minimizes downtime during maintenance, upgrades, or troubleshooting in production networks.
