In order for various manufacturers

Governing standards
In order for various manufacturers to be able to develop components that function compatibly in fiber optic communication systems, a number of standards have been developed. The International Telecommunications Union publishes several standards related to the characteristics and performance of fibers themselves, including

ITU-T G.651, "Characteristics of a 50/125 μm multimode graded index optical fibre cable"
ITU-T G.652, "Characteristics of a single-mode optical fibre cable"
Other standards specify performance criteria for fiber, transmitters, and receivers to be used together in conforming systems. Some of these standards are:
fiber optic salary
100 Gigabit Ethernet
10 Gigabit Ethernet
Fibre Channel
Gigabit Ethernet
HIPPI
Synchronous Digital Hierarchy
Synchronous Optical Networking
Optical Transport Network (OTN)
