10g-lrm on 62,5 fiber

Unanswered Question

The question is about maximim link length using 10g-lrm over 62,5 micron fiber. Specs show it is up to 220 m but cisco recommends to use mcp on transmitters as i understand. Some other sources don't mention necessity of mcp. Need to deploy 10g on old fiber links up to 150 meters without mcps. And there is no opportunity to test it before. Please advise who experienced the same situation
Thanks for advance

More : I've read that the maximum loss budget over the link is about 1,9 db and that the MCP itself would attenuate at least 2 db (it would be over the total loss budget, if so this standard would not have any usefulness...). 

This standard is intended for legacy fiber optics like FDDI and OM1. Are there any guidelines that describe in which conditions such fiber will work with 10GBASE-LRM ? 

- How many fibre junctions are allowed ?

- If there are more junctions, by which distance will it decrease the 220 m standard distance ?

- Are there any test method to check if a given link will pass or fail with 10GBASE-LRM ?

Thanks in advance !
