ART004_SM MM Indoor Duplex Optical Cable Tight Buffer


SM MM Indoor Duplex Optical Cable Tight Buffer refers to a specific type of indoor fiber optic cable construction. Here is a breakdown of what that string of terms means:

Decoding the Terminology


SM / MM: Stands for Single-Mode and Multi-Mode. This indicates the cable is available with either type of optical fiber. Single-mode is typically used for long-distance transmission (like campus backbones), while multi-mode is used for shorter distances within data centers or local area networks.


Indoor: These cables are designed specifically for use inside buildings. They are not suitable for outdoor environments. A key feature of indoor cables is that they must have a flame-retardant jacket to meet fire safety codes.


Duplex: This means the cable contains two independent optical fibers. They are usually arranged side-by-side in a "zipcord" or "figure-8" design, which allows them to be easily separated for individual connector termination. This configuration is standard for enabling simultaneous transmit and receive (bi-directional) data transmission.


Tight Buffer: This describes the protective layer applied directly to the optical fiber. A tight buffer is a layer of material (often PVC, LSZH, or Nylon) extruded directly onto the fiber, typically bringing it to an outer diameter of 900 μm. This is different from a loose-tube design. A tight buffer provides mechanical protection and makes the fiber easy to handle and terminate directly with connectors, which is why it is the standard construction for patch cords and pigtails.

Parameter

Keyed Characteristic:

1.Low transmission attenuation and dispersion;
2.High Bandwidth with multimode fiber OM1/OM2/OM3/OM4;
3.Aramid yarn armouring ensures the tensile performance and good flexibility of the optical cable;
4.Lighter weight , compact structure and Small Diameter 2.0/3.0;
5.Flane retartant LSZH out jacket for indoor using.

Application:

As pigtails and patch cords;
As interconnect lines of equipments;
As optical connections in optical communication rooms and optical distribution frames;
In indoor cabling,especially used as distribution cable.

Products Overview

These cables from ARTICFIBER are typically constructed with the two tight-buffered fibers, surrounded by Aramid Yarn (Kevlar) for tensile strength, and encased in a flame-retardant outer jacket (often LSZH for Low Smoke Zero Halogen).

Because of this design, they are primarily used as:

Patch Cords and Pigtails: The most common application, connecting equipment to patch panels.
Equipment Interconnects: Direct links between switches, servers, and other active hardware.
Indoor Distribution: Short-distance cabling within a building's communication room or data center.

In short, when you see this full product description, it is referring to a 900 μm tight-buffered, two-fiber indoor cable available in either single-mode or multi-mode, designed for easy field termination and protected by a flame-retardant jacket.
