You could use either. What will really dictate which you use is based on the transmitter/receivers that you couple into them.
One of the big advantages of single-mode over multi-mode is not having to worry very much about mode dispersion. Lower dispersion means longer runs before needing any sort of special dispersion correcting devices. The trade-off is a single-mode fiber has much lower bandwidth available. Using WDM, a multi-mode fiber can easily transmit 20+ channels at 20 to 40 Gb/s per channel. Single-mode is essentially a single channel.
