Both of these are designed for deployment over shortwavelength multimode fiber. The
distance range for both classifications
ranges from as little as 2 meters to 300 meters. The difference between the two classifications
is that SR is designed for use over
dark fiber. The \_\_\_\_\_ standard
is designed for longer-distance
data communications and connects
to SONET equipment.
