That depends on the test results on your fiber span. If the fiber is clean, of high quality, and well-spliced, then there could be a little 'slop' in the loss budget. At that distance, dispersion may be more of a concern than attenuation. It all depends on what the test results look like.
You'll want to see at least the 2-point loss test results at 1550 nm through your fiber span from an OTDR. If the splices are good, you shouldn't see too much of a reflectivity spike at the splice points, but you will see reflections from any physical cross-connects or jumpers that are in the span.
With the 10GBASE-ER, your minimum transmit power is -4.7 dBm and your minimum receive power is -15.8 dBm
