OM4 fiber optic patch cable is a kind of high speed fiber optic communication patch cable, which adopts OM4 fiber as the transmission medium.OM4 fiber is a kind of multi-mode fiber, which can support high speed data transmission and long distance transmission. Its transmission bandwidth can reach 4700MHz/km, which is nearly 50% higher than that of OM3 fiber.OM4 fiber optic patch cable usually adopts dual-core or quad-core design, which can support bi-directional transmission or cross-transmission. Its connector usually adopts different types of connectors, such as LC, SC, FC, etc., to adapt to different fiber optic connection needs.
