Review: work well - took me long, but i got a 100g switch to test this. i had no issue with it. it talk just fine to other 100g module. i think i'm able to get 100ish gbps. i had other bottleneck i have to deal with. but so far, so good. no issue. Review: Works well, fair price, good compatibility - Good value for a 100 gigabit homelab environment. Currently $38, easy to justify when expanding my use of 100 gigabit Ethernet at home with an older Arista 40/100 switch. If you're expanding faster than I am, the four-pack of this item is an even better deal. No complaints or issues so far. ## Features - 100gigabit QSFP28 Optical Transceiver Module is designed for use in 100GBASE Ethernet throughput up to 100m over OM4 multimode fiber (MMF) using a wavelength of 850nm via a MTP/MPO-12 connector. - Data Rare: 10/100/1000Mbps&1gbps/10/100Gbps.Support 100G to 4x25G Breakout Application. - Hot Pluggable QSFP28 MSA Compliant.
