Sarokal Test Systems provides innovative test solutions for fronthaul networks. Our CPRI, eCPRI, OBSAI, JESD204, Ethernet and upcoming IEEE 1914 solutions enable users like chipset vendors, fronthaul equipment manufacturers, and telecom operators to develop, test and verify their 4G and 5G network devices. 
Sarokal X-STEP™ products provide means to generate, capture, and analyze bit accurate fronthaul traffic with various line rates and protocols. With the 100% visibility and control over fronthaul traffic, X-STEP can ensure full interoperability between fronthaul devices already in the early R&D development phase as well as in the field. 




Sarokal Test Systems Oy was founded in 2013, when the product business was spun off from Sarokal Solutions that developed the first generation products in 2009. The move was necessary to be able to serve more customers in different fields of industry.

The company is based in downtown Oulu, a city of 200 000 people in the northern part of Finland, roughly 200 km south of the Arctic Circle. Oulu combines Northern hospitality, nature, and culture with modern technology and it is said to be the IT capital of Finland.
