Figure 3:
Mechanical Dimensions of a SFP module
The dimensions are in millimeters (inches)
9.7. Differences between SM and MM Fibers
The main difference between MM and SM fibers is that the former has much larger core diameter. Typi
-
cally, MM has a core diameter of 50 or 62.5 µm and a cladding diameter of 125 µm, while a typical SM
fiber has a core diameter between 8 and 10 µm and a cladding diameter of 125 µm.
