Optical Network Monitoring
Remotely accessible DWDM Optical Channel Monitor
The A1820 Optical Channel Monitor is an ultra-high performance DWDM channel monitor ideal for DWDM transmission systems with channel monitoring requirements. The A1820 monitors DWDM signals on 100GHz spacing. The optical characteristic of the entire C band are updated on a 1 second basis. The A1820 can optionally support up to four monitors, each of which operates independently. These channels can be used to monitor both eastbound and westbound traffic simultaneously.
The A1820 OCM is well suited to monitor networks employing WDM equipment such as Avvio Networks’ ROADM and A15xx series products and can be used in conjunction with Avvio Networks’ GUI based Element Management System.
The EMS uses a SNMP V2 MIB to communicate with the OCM, and provides a graphical depiction of the network’s current status, including channel power and OSNR. The A1820 and EMS allow an operator located in a remote NOC to immediately detect and respond to network problems related to wavelength power, and to view network segments to determine which wavelengths are currently in use.
