| MRV Products Distance Extension
 
 
   Another 
key application for SFPs is in distance extension. Here we see an SFP-based 
signal regenerator extending fiber optic cabling to long distances for very low 
cost. With 3-R signal regeneration the number of hops in a Gigabit Ethernet 
network is virtually unlimited, and SONET/SDH networks can be extended for long 
distances as well. MRV provides a range of single-mode pluggable optical 
interfaces to enable the widest variety of network configurations.
