What speed does it support?

The provided specifications list a data rate of 25Gbps. The product is also categorized as 25GBASE-SR, which aligns with 25 Gigabit Ethernet operation. No other speed grades are given in the supplied data, so 25Gbps is the only supported rate that should be used for planning.

What fiber type is required?

The product is listed for multimode fiber, abbreviated MMF. It is also described in the category as 25Gbps 850nm LC MMF up to 100m, which confirms the intended fiber environment. Buyers should match it to LC-terminated multimode cabling.

What connector does it use?

The specifications state an LC connector. The category also references LC multimode fiber, reinforcing that the module is designed for LC-terminated links. No other connector type is included in the provided data.

What is the maximum distance?

The supplied information states connectivity up to 100m. The product is positioned as a 25GBASE-SR multimode module, so it is intended for short-range optical runs within that limit. The data does not provide a longer-distance alternative.
