Fiber Optic Cable Types
Typically customers will ask for either multimode or single mode fiber cable. They may be able to give you some specifics but not always. They may rely on you to decide the exact type of fiber they need. Every now and then you may have a more technical customer that asks for Fiber cable but gives you a specific type like OM3 fiber. Well what does that mean? What is OM3 or OM4 Fiber?
This section will review the more technical naming conventions and specifications for both Multimode and Single Mode Fiber.
Multimode Fibers – OM1, OM2, OM3, OM4 and OM5
Multimode fibers are identified by the OM (optical mode) designation and their specifications are outlined by the ISO/IEC 11801 standard. Multimode cable disperses the light into multiple paths as it travels down the core. This allows for higher bandwidth over short to medium distances. However, on longer cable runs, multiple paths of light can cause distortion at the receiving end, resulting in an unclear and incomplete data transmission. For this reason, Multimode is generally only used for short distance applications like data centers.
