The color of multimode indoor optical cable is

Multimode indoor optical cables are typically color-coded as orange for OM1/OM2, aqua for OM3/OM4, and lime green for OM5.Standard Jacket ColorsOM1 (62.5/125 µm): Orange jacket, often used in legacy networks for LED light sources and short-distance links .OM2 (50/125 µm): Grey or sometimes orange in older installations; supports higher bandwidth than OM1 .OM3 (50/125 µm, laser-optimized): Aqua jacket, designed for high-speed VCSEL-based networks, supporting 10, 40, or 100 Gb/s over short distances .OM4 (50/125 µm, laser-optimized): Aqua or sometimes violet depending on the manufacturer; offers higher modal bandwidth than OM3 for longer runs .OM5 (50/125 µm, wideband multimode): Lime green jacket; optimized for Short Wave Division Multiplexing (SWDM) but otherwise similar to OM4 for standard IEEE applications .Connector ColorsBeige connectors: Typically used for OM1 and OM2 multimode fibers .Aqua connectors: Used for OM3 and OM4 multimode fibers, matching the jacket color .Lime green connectors: Used for OM5 multimode fibers to distinguish them from OM4 .SummaryThe color-coding system, standardized under TIA-598, allows technicians to quickly identify the type of multimode fiber and its capabilities. Orange indicates legacy OM1/OM2, aqua indicates modern OM3/OM4, and lime green indicates OM5, ensuring proper installation and compatibility in indoor structured cabling environments .
