10M optical fiber bandwidth 10M, which is connected to the operator through optical fiber \x0d\. Compared with ordinary 10M, the bandwidth is the same, but the transmission medium is different, and the optical fiber has small delay, high speed, reduced signal attenuation and less packet loss. \x0d\ network speed means MB/s, and the actual download speed of 10M fiber is18 =1.25mb/s \ x0d \ theoretical value: 1byte=8bit, that is1b. We use Thunder Download to talk about the former. And operators, they all use the latter, probably because of the good value. This is why the broadband of 1M is only about 125KB/ s now. Divided by 8. You should know the common sense of 1M= 1024KB. 1024 divided by 8 is exactly around 125.
