It sounds like your application is something along the lines of what is
depicted in Figure 12. WDM Splitter Cable for Non-CWDM Applications?

I haven't used that specific part to do a 1310/1550 10G network, but we
have a similar part from Fiberdyne (a Dual Window Mux) to do a SONET (at
1310) overlay on a DWDM signal.  We also have a 1000BaseLX overlay onto
DWDM systems and have even done a video signal at 1310 using these parts.

As long as you could run either optic over this cable without the
combiner/splitter, you should be fine.  It will introduce a bit of loss,
so make sure you account for that.
