OM5 is also multimode 50/125 fibre – but a newer standard designed to support higher data rates over a maximum transmission length of 550 metres. OM1 fiber provides 500 MHz·km at 1300 nm wavelength. This 1300 nm spec matters for LED-based legacy systems. Modern VCSEL systems focus on 850 nm performance. OM5 is the sole. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). OM3, OM4, and OM5 are types of multi-mode optical fibres commonly used in data centres and enterprise environments to support various network speeds and transmission distances, including 10 gigabit Ethernet (10G), 40 gigabit Ethernet (40G), 100 gigabit Ethernet (100G) and 400 gigabit Ethernet. Corning® ClearCurve® OM5 wide band optical fiber is designed to support Wavelength Division Multiplexing (WDM) operation over 850 – 953 nm wavelengths while offering the same bandwidth specifications at 850 nm as Corning® ClearCurve® OM4 optical fiber. Corning® ClearCurve® OM5 wide band optical. OM1 fiber typically comes with an orange jacket and have a core size of 62. 5 microns (µm) compared to the 9 microns (µm) core diameter of single-mode fiber.
