[c-nsp] Optical Transceiver Module

[Lincoln Dale]

in Cisco terms:
    80km would be covered by DWDM, CWDM and ZX optics.
    20km would be covered by DWDM, CWDM, ZX and ER/ER+ optics
    15km may be covered by LR optics at a pinch. would have to be very 
good fiber, few patches etc.  you'd need to know exact fiber 
charactieristcs as to whether its possible.  but if not, then it'll be 
the same as 20km above.

http://www.cisco.com/en/US/prod/collateral/modules/ps5455/white_paper_c11-463661.html 
provides all the details you're looking for.
as others have indicated "distance" is more of a 'typical' thing rather 
than an absolute science.


cheers,

lincoln.
