PMP650 Fiber Cable?

Hoping for some help or suggestions from the community because I am stumped by something that seems so simple...

Just purchased the Fiber SFP for my PMP650.  Here is a link to the manual that shows the long cable gland that comes with the SFP and screws onto the exterior of the radio to accomodate the fiber connectors and make a waterproof connection.  Scroll down to page 5-47 and 5-48.

The problem i have is that I am using field installable LC fiber connectors and they are not the most durable of connectors.  I would like to purchase a waterproof, exterior, 2 strand, LC-LC, Singlemode fiber pacth cable, preferrably black and around 50' long.  And for the life of me I can;t find this.  Everything I found at UBNT and, etc.. has exterior, waterproof fiber cables but they are multi strand and they won;t fit into the cable gland.  I just need to strands. 

For you guys running these on towers, what the heck are you using to plug into the fiber SFP on these radios??

I did a quick search and found the following. The breakout portion might be to long but it gives you a start.
