Finisar 100G 4x28G Metro Tunable DWDM 30km (500km+ Amplified) CFP Optical Transceiver 2

Is 25G really more than 10G?

The new style of 100G CFP pluggable optics module builds on the 2nd Generation 100G Ethernet standard that was published in 2015 and uses four pairs of singlemode fibres each transmitting 25Gb/s of data using tuneable lasers in the C-band.
