Viewing 3 Fibers on a 1-Channel OSA

Hello everyone.

I have three fibers with FBGs manufactured on each of them. My Optical Spectrum Analyzer (OSA) Agilent 86142A, however, only has 1 channel. So I cannot view all three fibers on the OSA at once (I have to unplug one, and plug another in).

Is there any way of "combining" (excuse my superficial words) the three fibers, such that I can view all the fibers at once on the OSA?

Thank you!
