Re: Outsourced NOC Solutions

[Dave Cohen <craetdave () gmail com>]

There are two different approaches to deploying the fiber monitoring hardware that is effectively in line with the “get 
your gear off of my fiber” argument. If the monitoring service is intended for a specific customer, the signal will 
traverse a customer-specific pair. This is pretty rare though, for a wide variety of reasons that have been mostly 
mentioned here. 

The way this generally works then is that the provider reserves a strand or pair on the cable for monitoring purposes 
and uses the characterization data to make assumptions about the whole cable. This is pretty effective for “track down 
the precise location of a cut” or “why did this span just go from -18 to -30 for no apparent reason” and not 
necessarily the full gamut of characterization issues that can come up on other pairs of glass, which is still enough 
to meaningfully impact the part of MTTR that is under a provider’s control. For many of you consuming a dark fiber 
service today, this is the approach being used, so there’s no provider hardware touching your glass and certainly no 
lambda for your gear to contend with avoiding.
