The OP was asking about a single-strand 10GE product, not just "any" 10GE 
product, or even ordinary 10G DWDM products. Basically they're looking for 
a 10GE version of 1000BASE-BX, an integrated mux+transceiver in a standard 
pluggable package with a sigle strand connector, as desribed here:

http://www.cisco.com/en/US/prod/collateral/modules/ps5455/ps6577/product_data_sheet0900aecd8033f885.html

Everyone and their mother sells 10G DWDM gear (no CWDM though, probably 
because dealing with the dispersion of a wider band signal at 10G speeds 
is far harder than transmitting a narrow and stable 100GHz signal), but 
that has nothing to do with what they wanted.

Also note as always that Cisco doesn't actually make any of this gear, nor 
do they do anything even vaguely "different" or "interesting" with it. 
This is all just trivial tuned optics and passive filters that you can get 
from anyone (at better densities, with more channels, and with better 
optical characteristics too), all Cisco does is slap their logo on it and 
mark it up 10x.
