Sure, this is a fixed optics standard called 1x9 (1 row of 9 pins). If 
you're handy with a soldering iron and you can find someone to buy some 
1x9 transceivers you can swap it out easily, I used to do this with old 
Foundry "guaranteed failure" fixed optics before I realized it wasn't 
worth my time. :) You can surely replace the old LH optics with something 
modern that has a 30dB budget instead of the old 23dB (70km) stuff too.
