OM2 fiber optic patch cables
OM2 is a standard for multimode cable defined by ISO/IEC 100801, the 50/125 OM2 multimode fiber was first invented by Corning in the 1970s. OM2 fiber optic cable refer to the commonly used 50/125 traditional fiber cable.
OM2 was not widely used before the 1990s but now it has grown to be popular and even the first choice for newly established networks compared with OM1 the 62.5/125 multimode fiber.
OM2 was not widely used before the 1990s but now it has grown to be popular and even the first choice for newly established networks compared with OM1 the 62.5/125 multimode fiber.
OM1 and OM2 are both orange jacketed cable, and you cannot judge from the outer diameter to identify OM1 and OM2 fiber cable, because the 50/125 and 62.5/125 refer not to whole cable diameter but to the fiber inside. Usually there will be words printed on the cable jacket showing its specifications; it will describe the fiber type. OM2 fiber cable max attenuation is same as OM1 fiber cable, but the overfilled launch is much higher than OM1 using 1300nm. ADTEK produce OM1, OM2 and the OM3 10gig multimode fiber optic cables and assemblies.
