General thoughts

• Like cars- look for version 2
• Look for a company
• -that has been around a couple of years
• -has money in the bank
• -Long haul has telecom experience
• -Metro does more than optronics
• Look for indepth NMS capabilities
• How do you want to use this transport equipment
• for the next 3-5 years (ref T.West
  statement)
• -ring
• -linear
• -protection capability

Details

• -rack space
• -common chassis
• -APS
• -ROADM (max filter choice)
• -8 lambda per transponder (min. part numbers)
• -GMPLS (control plane options)
• -Auto power adjust
• -NDPS

4
Details (continued)

• -ITU-T frequencies (spacings supported)
• -how many bands C, L
• -per lambda stats
• -per lambda stats per encoded protocol
• -O to O (??need??)
• -LAN PHY WAN PHY
• -How are redundant lambda switched
• -configuration tools (incorporating design
  options)

5
Like to have

• -common chassis for 5 years
• -lasers switchable over the ITU-T spectrum
• -ROADM now
• -combined function on a substrate
• -per lambda monitoring
• -cost of L2/L3 equipment but!
• -reliability of SONET equipment
• -maximum monitoring
• -modular function pushed to a L2/L3 equipment

Look at what your needs are

• -Metro
• -RON
• -Long Haul
