Title: Best optical book out there for SDH and SONET. Period!
Review: I had been struggling to find an Optical book that covered SDH in detail from a Cisco ONS perspective. Most books out there only focus on SONET. It is almost like SDH does not exist. This book covers both, SONET and SDH (in a detail you cannot imagine). It covers everything from TDM to Metro Ethernet, RPR and MPLS over SDH. Finally a solid SDH book!
