This is a wide-band multimode fiber (WBMMF) jumper designed specifically for 100G/400G/800G and above ultra-high-speed data center shortwave division multiplexing (SWDM) technology. It is an evolution of the OM4 fiber, with its core advantage being that it can transmit multiple wavelengths using only a pair of fibers (duplex), thereby significantly increasing link capacity, reducing cabling complexity and cost. It is an ideal choice for future data center high-density, high-bandwidth connections.
