MPO Fiber Optics Cables FAQs
MPO stands for Multi-Fiber Push On. This connector is commonly used to terminate multi-fiber ribbon connections in indoor environments. The MPO connector can be either male or female. They provide up to 24 or more fibers in a single connector pushing up to and beyond 100 Gbps data transmission. MPOs are paving the way for increased data transmission speeds and rack density.
The MPO cables could be Multimode or Single mode. Multimode fiber cable is prefixed with ‘OM’ and Single mode fiber cable is prefixed with ‘OS’. The Popular Multimode fibers are OM4 and OM5 whereas the Single mode fibers are OS2.
OM4 has a suggested jacket colour of Magenta and has a core size of 50 micrometers (µm). It supports 10 Gigabit Ethernet at lengths up 550 meters and it supports 100 Gigabit Ethernet at lengths up to 150 meters. OM4 fibre is optimized for laser based equipment that uses fewer modes of light.
OM5 multimode fibre is the advanced version of the OM4 fibre. It is a Wideband multimode fibre (WBMMF) that can support wavelengths between 850nm and 953nm. It is also designed to support the short wavelength division multiplexing (SWDM)—one of the new technology for 40G/100G connection.
OS2 Single mode fibre cable is an outdoor loose tube optical fibre cable and is suitable for outdoor applications where the cabling process applies no stress to the optical fibres. The attenuation of an OS2 fibre is lower than an OS1 .This cable type over the distance will allow 1 to 10 gigabit Ethernet depending on the switch module you install.
The three methods for proper polarity are matched with different MPO types. Type A (Straight Through) cable also known as straight cable. Type B cable (Crossover Cable) uses key up connector on both ends of the cable. Type C cable (Pairwise Flip Cable) looks like Type A cable with one key up connector and one key down connector on each side.
MPO connectors enable a network to consolidate large amounts of fiber strands in a compact connector. Especially useful in the migration from 10G to 40G and 100G data transfer rates. MPO cables are available in 8, 12 and 24-fibre MPO assemblies with LC/MPO connectors according to customer’s choice.
The MPO connector can be either male or female. The MPO-LC breakout cable allows the redistribution of various optical fibers to individual devices without additional networking equipment. Some of the popular connector ends are MPO Female to MPO Female; MPO Female to LC and MPO Male to LC.
The jacket type is LSZH jacket which is free of halogenated materials which can be transformed into toxic and corrosive matte during combustion. LSZH materials are used to make a special cable called LSZH cable, which is a good choice for inner installations.
