•
4 likes•2,457 views
ADVA Optical Networking's direct detect open optical layer is specifically designed for the ICP and CNP market. The new solution is a key expansion of the ADVA FSP 3000 CloudConnect™ platform and offers a compelling alternative for customers who want to avoid the expense of traditional coherent solutions. The direct detect technology is available in two distinct formats. It can either be bought as an Open Line System (OLS) in a disaggregated manner or as a complete solution that includes the terminal and the line system. One compelling feature of ADVA Optical Networking’s OLS is its SmartAmp™ technology that enables direct detect transmissions to be transported up to 100km.
