This 20M Multimode Duplex Fiber Optic
Patch Cable (62.5/125) - LC to ST cable has ceramic ferrules and a 62.5/125
Micron core, this cable is suitable for high speed data transmissions such that you would find in Ethernet (10 Mb/s) to Gigabit Ethernet (1 Gb/s) networks.
A patch cable or patch cord (sometimes patchcable or patchcord) is an electrical or optical cable, used to connect ("patch-in") one electronic or optical device to another for signal routing. Devices of different types (ie: a switch connected to a computer, or switch to router) are connected with patch cords. Patch cords are usually produced in many different colours so as to be easily distinguishable, and are relatively short, perhaps no longer than two metres. Types of patch cords include microphone cables, headphone extension cables, XLR connector, RCA connector and 1/4" TRS connector cables (as well as modular ethernet cables), and thicker, hose-like cords (snake cable) used to carry video or amplified signals. However, patch cords typically only refer to those short ones used with patch panels.
A micrometre or micron (American spelling: micrometer; symbol µm) is one millionth of a metre, or equivalently one thousandth of a millimetre. It is also commonly known as a micron. It can be written in scientific notation as 1×10-6 m, meaning 1/1 000 000 m.
