Optical channel Monitor
1 DESCRIPTION
1.1 Product Function
Optical Channel Monitor (OCM) is subjected to DWDM system. The module de-multiplexes Flex Grid channel optical signals within the range of 1528nm to 1568nm through optical tunable filter, tapped from an optical network. The results, which including channel power, channel wavelength are provided to the customer.
1.2 Product Application
Ø Based on Optical tunable filter
Ø High dynamic range
Ø Telcordia GR-1312-CORE
Ø Compact size with 1x8 switch
