Tips for testing and troubleshooting today’s DWDM networks

  • 2022年2月23日

Kevin Peres

Applications Engineer, Advanced Technologies and Solutions

Kevin has been with EXFO for 18 years and has been involved in the telecom industry for 29 years. Starting in excavation as a laborer, Kevin traded in his shovel for a backhoe laying cable across the US. He later worked for a Tier 1 service provider as a splicer and tester, working on new installs and disaster recovery. Kevin became an Operations technician, turning up and maintaining DS1 to 10G systems. Leveraging this field experience, Kevin delivers a unique perspective which shows in his educational approach when delivering expert content through webinars or seminars. 

Technologies like 5G and cloud services have fueled a tremendous increase in bandwidth demand. Installation of high-count fiber and an increase in bandwidth to 100G+ have helped meet some requirements, but to fully meet unsatisfied demand, advanced technologies like dense wavelength division multiplexing (DWDM) must be deployed. DWDM has long been a technology used on backbone transport but it’s now pushing out into the metro environment to feed bandwidth-hungry services. 

Front line technicians and contractors who install, maintain, and troubleshoot metro services today will need to prepare for advanced technologies like DWDM.  

 This 45-minute webinar will cover the following topics: 

  • introduction to DWDM (5 minutes) 
  • architecture and components of a DWDM network (10 minutes) 
  • passive vs active xWDM testing (5 minutes) 
  • qualifying and maintaining a healthy network (20 minutes) 
  • understanding OSNR and how it impacts your network (5 minutes)
