As the requirements for greater bandwidth have grown in recent years, many users look to purchase multimode fibers based on the [ISO 11801](http://en.wikipedia.org/wiki/ISO/IEC_11801) standards (OM1, OM2, OM3, & OM4) to meet the needs of their applications. With several manufacturers providing multimode optical fibers, below are the most popular brand & types from each manufacturer: **OM1**       Corning®InfiniCor®       Draka Standard Multimode       OFS Standard Multimode **OM2**       Corning® ClearCurve®       Draka MaxCap / BendBright       OFS LaserWave G+ / Flex G+ **OM3**       Corning® ClearCurve®       Draka MaxCap / BendBright       OFS LaserWave 300 / Flex 300 **OM4**       Corning® ClearCurve®       Draka MaxCap / BendBright       OFS LaserWave 550 / Flex 550 ***Questions or requirements for any of the fibers listed above?
