The OM4 Laser-Optimized Multimode Fiber (LOMMF) "aqua" cable, for use with 40/100 Gb Ethernet applications. This technology, 50/125 um, LC/LC fiber optic cable, provides three times the bandwidth over conventional 62.5 um multimode fiber, with performance rivaling that of single mode cable, at a much reduced cost. LOMMF cable allows 40/100 Gb serial transmission over extended distances in the 850 nm wavelength window, where low-cost Vertical Cavity Surface Emitting Lasers (VCSELs) enable a cost-effective, high-bandwidth solution. LOMMF is ideally suited for LANs, SANs, and high-speed parallel interconnects for head-ends, central offices, and data centers.
