Compatible with major switch brands — share your equipment model to confirm coding before ordering. 3-year warranty included.
The 100GBASE-LR1 QSFP28 transceiver delivers 100 Gbps over single-mode fiber (SMF) using 1310 nm with a duplex LC connector, up to 10 km. It is hot-pluggable, QSFP28 MSA-compliant, and supports DDM digital diagnostics.
100G QSFP28 is the standard spine-leaf fabric speed: leaf uplinks, storage fabrics and metro 100G transport. SR4 uses MPO multimode to 100 m; LR1, ER4 and ZR4 cover 10–80 km over single-mode LC for campus and metro spans.
Confirm your switch port is rated for 100G and uses the same 100GBASE-LR1 interface before installing. Share the switch model to confirm coding; every module ships with a 3-year warranty and free technical support.
