Sweet stuff.    I do have Mikrotiks with Dual GigE Fiber Ports if someone is
interested.

Since you are using GBICs have you considered using CWDM along with 
passive ADMs instead? Passive ADMs don't require any power and could be 
used at each customer location to drop a single channel of light that 
you plug into the GBIC. This way if a single customer's equipment goes 
down the rest of the ring stays up. With CWDM you only have 8 channels 
of light giving you a max of 8 gigs shared across your ring, but that is 
probably fine considering you only have 2 gigs with your current setup.
