Fiber Optic Cable 12Core OM3 Brand Rex

Optical fiber is a string of very thin filaments of glass whose diameter is the diameter of a human hair. The above fibers form into organizing coils and optical cables. Optical fiber is used to send optical signals over long distances.

The above fiber optic cable is of OM3 type, the difference of each of which is described below.

Differences between OM1, OM2, OM3 and OM4 fiber optic cables:

When preparing and purchasing fiber optic cable, we may come across a term called OM on the box or cover of fiber optic cable, which we will address in this article. OM, which stands for Optical Mode and is used only for fiber optic multimode cables, is a standard defined under ISO / IEC 11801 that classifies fiber optic cables based on the operating frequency used and the distance that the cable supports. This division divides the cables into four groups OM1, OM2, OM3 and OM4, each with its own specifications.

Specifications of OM1 fiber optic cable

This cable is orange, has a core of 62.5 micrometers, supports a distance of 300 meters and has been used for many years. It supports a maximum distance of 33 meters for 10G speeds and is reliable for up to 275 meters for a gigabit speed of up to 275 meters. This type of cable is mostly used for local networks with a speed of 100 Mbps or fast ethernet networks up to a speed of one gigabit.

Specifications of OM2 fiber optic cable

The core of this type of fiber is 50 micrometers and supports up to 2 km for speeds of up to 100 Mbps. Up to 550 meters, it offers a speed of one gigabit, and for 10G speeds, it only supports up to 82 meters.

Specifications of OM3 fiber optic cable

The core of this type of fiber is 50 micrometers and supports up to 2 km for speeds of up to 100 Mbps. Up to 550 meters, it offers a speed of one gigabit, and for 10G speeds, it only supports up to 300 meters. There is support for 40G and 100G speeds in this type of cable

Specifications of OM4 fiber optic cable

The core of this type of cable, like OM2 and OM3 cables, is fifty micrometers and supports up to 2 km for speeds of up to 100 Mbps. It offers a speed of one gigabit up to a distance of 1000 meters and supports up to a distance of 550 meters for 10G speeds. There is support for 40G and 100G speeds in this type of cable.
