2.0 eCPRI Testing for 10G/25G/25G with RS-FEC

eCPRI is designed to comply with the more stringent requirements brought on by 5G standards for fronthaul solutions based on

CPRI/OBSAI. These include:

Increase bandwidth

Bandwidth scalability and flexibility

Low latency

Flexibility in functional split options between Remote Unit (RU) and Centralized Unit (CU)

Note:

 eCPRI testing availability depends on the test platform and module. Options and features described in this manual may not be

available on all software versions and platforms. Refer to the latest specification sheet on 

www.veexinc.com

 for a breakdown of

available test modes for each platform and module.
