I did that. I had to take a 2 week business trip 5,000 miles away from my daughter when she was about the same age as your baby. If your husband has the option to come with you great - but that wasn't an option in our case.
The baby was fine - I was a bit of a mess. It was very difficult, esp the trip there and during down time. I second the photo and skype suggestions. Skype especially was a life saver for me. My husband and Mom (who helped him out) were also great about taping lots of their day and sending me the videos. It was really comforting as well.
I spent a lot of time working - more than I needed to really, but it helped to be completely engrossed in something else. Also, remembering why I was doing this job and the benefits to DD helped.
Your baby will not forget you (I promise ) and it will be a wonderful opportunity to have him bond with his father. I know every household is different, but in ours, I did most of the childcare when DD was an infant so my husband and mom loved having her all to themselves.
