When designing a structured optical cabling system, the most basic question is inevitably: what fiber type to use. These are two standards for single mode fiber optic cabling from a total of six types of fiber that are generically used today known of “OF types” (OM1, OM2, OM3, OM4 for multimode and OS1, OS2 for single mode.) There is a great deal of confusion about the purpose and meaning of cabled single mode optical fiber Categories OS1 and OS2. So here is the explanation of the differences between the specifications of OS1 and OS2.

The difference between OS1 and OS2 fiber optic cables mainly lie in the performance due to cable construction. The performance is less dependent on optical fiber performance and more dependent on how...
