Optical Insertion Loss estimation:
• Example 3 of Origin to Remote (Point-to-Point) (link) Loss
Calculation with two intermediate, OADM (client Drop, Add and
Pass-Thru) stages – assumes one λ per OADM Drop-point.
• Calculates accumulated typical and maximum path Losses from
Origin through two OADM stages to Remote end-point.
