一、接口速率

在sub6G低频段100MHz谱宽，64T/64R Massive MIMO，采用eCPRI 接口的5G前传速率为25Gb/s。目前主要5G设备都采用25G接口，部分厂家是2X10G接口。

应用场景	业务类型	速率(Gbps)
4G基站前传	CPRI option 1	0.61
4G基站前传	CPRI option 2	1.23
4G基站前传	CPRI Option 3	2.46
4G基站前传	CPRI Option 4	3.07
4G基站前传	CPRI Option 5	4.91
4G基站前传	CPRI Option 6	6.14
4G基站前传	CPRI Option 7	9.83
5G基站前传	CPRI Option 10	24.33
5G基站前传	eCPRI	25.78

option 8: 10137.6 Mbit/s, 64B/66B line coding (20 x 491.52 x 66/64 Mbit/s)

option 9: 12165.12 Mbit/s, 64B/66B line coding (24 x 491.52 x 66/64 Mbit/s)

option 10: 24330.24 Mbit/s, 64B/66B line coding (48 x 491.52 x 66/64 Mbit/s)

二、接口数量

单宏站，100MHz频谱，需要3个25G接口，200MHz频谱下，需要6个25G接口，在与4G共站以及更宽频谱资源时，单个基站将会需要6个/12个前传接口。
