Tip of the Week:
Many fiber optic carriers are installing passive DWDM and CWDM multiplexer systems to economically increase their fiber capacity. If these multiplexers are installed at locations where access is not controlled by the carrier, it may want to consider two possible security issues that can be difficult to remotely detect.
Unauthorized connection to and theft of empty DWDM or CWDM channel capacity.
Disruption of DWDM or CWDM system communication due to inappropriate equipment connection to empty channel ports.
Both issues can occur and cause problems for the carrier and its customers. To attempt to prevent such security breaches, DWDM and CWDM multiplexers are available with channel locking mechanisms to guard against such unauthorized actions with unused channels.
Pertinent Products/Services:
Now available “Channel Guard” in all of our DWDM Lite and CWDM Lite passive multiplexers.
Channel Guard option allows you to disable and manually lock out one or more DWDM or CWDM channels to prevent unauthorized use.
This feature is useful in situations where passive DWDM or CWDM multiplexers are installed at customer or other locations and access is not controlled by your company. It prevents unauthorized personnel from connecting communication equipment to and using empty channels in your passive DWDM or CWDM multiplexing systems without your knowledge or approval. It guards against theft of transmission channels and loss of valuable channel revenue in your passive DWDM and CWDM systems. It also guards against possible DWDM and CWDM total communication system disruption due to inappropriate equipment connection to channel ports.
