Introduction to OM2 fiber optic patch cord

Definition and characteristics:
OM2 fiber optic patch cord is a multi-mode fiber optic patch cord used to transmit optical signals in applications such as local area networks (LAN) and data centers. It is a fiber grade commonly used in fiber optic communications.

OM2 optical fiber patch cord uses multi-mode optical fiber, which has high bandwidth and transmission performance. It is typically used for data transmission over shorter distances and at medium speeds. OM2 fiber optic patch cord supports 1Gbps (gigabits per second) optical signal transmission and is suitable for network applications based on Ethernet and Fast Ethernet.

Multimode optical fiber classification:
Within the classification of multimode fiber optic patch cords, different standards and levels are used to describe their performance and characteristics. The following are the OM2 levels in the fiber optic patch cord classification and their characteristics:

OM2 grade fiber optic patch cord is a 50/125 micron multi-mode fiber optic patch cord. The numbers 50 and 125 represent the fiber’s core diameter and cladding diameter, respectively, in microns. This fiber uses light wavelengths of 850 nanometers or 1300 nanometers in optical signal transmission.

OM2 optical fiber jumpers have higher bandwidth and transmission capabilities than lower-level optical fibers (such as OM1 level). It can support optical signal transmission rates up to 1Gbps and is suitable for Ethernet, Fast Ethernet and some fiber optic communication applications.

It should be noted that the transmission distance of OM2 fiber optic jumpers is shorter than that of OM3 and OM4 grade fiber optic jumpers. Generally speaking, the transmission distance of OM2 fiber optic patch cord is less than one kilometer, which is suitable for shorter distance data transmission needs.

OM2 fiber optic patch cord is a commonly used multi-mode fiber optic patch cord, suitable for short distance and medium speed data transmission. It has 50/125 micron optical fiber specifications and can support 1Gbps optical signal transmission rate. When selecting fiber optic patch cords, the most appropriate fiber grade needs to be determined based on specific application requirements and transmission distance.

Structure and parameters of OM2 fiber optic patch cord

structure:
The structure of OM2 fiber optic patch cord is similar to other multimode fiber optic patch cords and usually consists of the following parts:

  1. Fiber optic core (Core): The fiber optic core is the central part of optical signal transmission and is composed of high refractive index material (usually glass). In OM2 fiber optic patch cords, the fiber core diameter is 50 microns.

  2. Cladding: The cladding is the outer layer of the optical fiber core. It is made of low-refractive index material (usually silicon) and is used to keep the optical signal in the optical fiber core. In OM2 fiber optic patch cords, the cladding diameter is 125 microns.

  3. Jacket: The jacket is the outer layer that protects the optical fiber. It is usually made of materials (such as PVC or LSZH) that are wear-resistant, pressure-resistant, and flame-retardant. Jackets provide protection for optical fibers from physical damage and environmental influences.

parameter:
OM2 fiber optic patch cord has the following important parameters:

  1. Core Diameter: The fiber core diameter of OM2 fiber optic jumper is 50 microns. It determines the path of optical signal transmission in the optical fiber.

  2. Mode Field Diameter: The mode field diameter refers to the diameter of the mode field of the optical signal (that is, the light intensity distribution propagating in the optical fiber). In OM2 fiber optic patch cords, the typical mode field diameter is approximately 8.6 microns.

  3. Typical Attenuation: Attenuation is the signal loss of optical signals during optical fiber transmission. Typical attenuation levels for OM2 fiber optic patch cords are 0.5 to 3.5 decibels (dB) per kilometer.

These parameters are important indicators used to describe and evaluate the performance and transmission characteristics of OM2 fiber optic patch cords. Smaller core diameter and mode field diameter, lower typical attenuation values can provide better transmission performance and shorter transmission distance.

It should be noted that specific OM2 fiber optic patch cord parameters may vary depending on manufacturers and suppliers. When selecting and using OM2 fiber optic patch cords, it is recommended to refer to the relevant technical specification sheets and data provided by the supplier to ensure that it meets the required performance requirements.
