I'm a routing guy mainly working with ISIS/BGP for my company in our core space. I have an opportunity to get involve with our L2 DWDM network. We are a Cisco shop using NCS2K as DWDM nodes. But before jump into learning the NCS specific stuff, I would like to take a vendor neutral training course in Optical fiber testing with OSA/OTDR, OTN, DWDM signaling, OSNR/dispersion....etc. I think this will help me understand how to build out a DWDM network from ground up. I'm hoping someone I could get into designing network for my company. Thanks in advance,James
