As data transmission demands continue to grow, understanding
the different types of fiber optic cables is crucial for network professionals.
Let's break down the key differences between OS2, OM1, OM3, OM4, and OM5 fiber
optic cables:Single-mode vs. MultimodeOS2 is a single-mode fiber, while OM1, OM3, OM4, and OM5 are
multimode fibers4.Core Size and Light SourceOS2: Single-mode with a small core, uses laser light
sources4.OM1: 62.5/125μm core, uses LED light sources13.OM3, OM4, OM5: 50/125μm core, use VCSEL (Vertical-Cavity
Surface-Emitting Laser) light sources13.Bandwidth and DistanceOS2: Highest bandwidth, suitable for long-distance
transmission (kilometers)4.OM1: 200MHz*km bandwidth, supports 10GbE up to 33m13.OM3: 2000MHz*km bandwidth, supports 10GbE up to 300m13.OM4: 4700MHz*km bandwidth, supports 10GbE up to 550m13.OM5: 28000MHz*km bandwidth, designed for 40Gb/s and 100Gb/s
transmission13.Jacket ColorOS2: YellowOM1 & OM2: OrangeOM3 & OM4: AquaOM5: Lime Green13ApplicationsOS2: Telecom, long-distance data center connections4.OM1: Legacy systems, short-distance networks4.OM3/OM4: Modern data centers, enterprise networks4.OM5: Future-proof data centers, high-speed short-range
connections4.Choosing the right fiber type depends on your specific
needs, considering factors like transmission distance, speed requirements, and
future scalability. Understanding these differences will help you make informed
decisions for your network infrastructure.
