Frequently Asked Questions
What is 100GBASE-LR4 and how does it differ from other 100G standards?
100GBASE-LR4 is a long-range 100 Gigabit Ethernet standard that uses four 25G lanes over multimode fiber, achieving 10 km transmission distances. Unlike 100GBASE-SR4 (short-range), the 100GBASE-LR4 QSFP28 module extends connectivity across larger network footprints, making it ideal for campus interconnects and metropolitan deployments where distance is a critical factor.
Is the ENET SM100G-LR compatible with my Chelsio network adapter?
Yes, this Chelsio-compatible 100GBASE-LR4 transceiver is specifically verified for interoperability with Chelsio T5 and T6 series network interface cards. Always verify your specific adapter model in the Chelsio compatibility matrix before deployment to ensure optimal performance.
What does TAA compliance mean for procurement?
TAA (Trade Agreements Act) compliance certifies that the 100GBASE-LR4 QSFP28 transceiver meets U.S. federal procurement standards and can be purchased by government agencies and contractors. This designation ensures the product meets domestic content and manufacturing requirements for regulated environments.
Can I use this QSFP28 module with OM3 fiber, or do I need OM4?
The ENET SM100G-LR long-range transceiver supports both OM3 and OM4 multimode fiber. OM4 fiber provides better performance and longer distances, but OM3 is fully compatible. For maximum range and signal quality, OM4 fiber is recommended, though OM3 will function reliably within appropriate distance parameters.
