The converter provides transparent data 
conversion between fiber optic devices that 
utilize multi--mode fiber and single mode fiber. A 
bidirectional digital I/O port is also provided to 
allow the conversion between TTL/CMOS and 
optical signals. The transmission distance for 
single-mode is greater than that of multi-mode. 
Single mode is ideal for longer "metropolitan 
distances" and multi-mode is well suited to short 
premises installation.
