The Difference Between Single-mode Multimode

- Sep 29, 2018-

Single-mode fiber is cheap, but monolithic devices are much more expensive than similar multimode devices.

Single-mode devices can usually run on single-mode fibers or on multimode fibers, while multimode devices are limited to running on multimode fibers. The 10G module went through the development from 300PIN,XENPAK,X2,XFP, and finally realized the transmission of 10G signal with the same size as SFP, which is SFP+.

With its miniaturization, low cost and other advantages, SFP meets the high density requirements of the optical module, which was pushed from the 2002 standard, and has replaced XFP as the mainstream of the 10G market by 2010.
