SC-SC Fiber Optic Patch Cord, Single-Mode G.657.A2, Outdoor, 125 m, Armored 3 mm, Black

SC-SC Armored fiber optic patch cord, 125 m long — a ready-to-use armored fiber optic cable designed for connecting telecommunications equipment and routing optical lines. It is manufactured using ITU-T G.657.A2 single-mode optical fiber and is equipped with SC-SC connectors on both ends.

G.657.A2 optical fiber provides enhanced bend resistance and reduced additional optical losses when the cable is routed with small bending radii. This makes the patch cord well suited for FTTH, FTTB, and PON networks, subscriber connections, and installations in confined spaces.

The cable has an outer diameter of approximately 3 mm and features an Armored construction with a steel protective element. The armor increases resistance to mechanical damage, compression, accidental impacts, and bending during installation and operation.

The outer jacket is made of LSZH material (Low Smoke Zero Halogen), which provides reduced smoke emission and contains no halogens. This makes the cable well suited for installation inside residential, office, technical, and telecommunications premises.

Where it is used

The patch cord is designed for organizing and connecting fiber optic lines. Thanks to the use of G.657.A2 fiber, it is especially convenient for subscriber networks where the cable must be routed in confined spaces or with relatively small bending radii.

It can be used in apartments, private houses, offices, entrances, technical rooms, server rooms, and telecommunications facilities.

Suitable for installation:

• in cable ducts and trunking;
• in plastic and other protective conduits;
• in cable trays;
• in telecommunications and server cabinets;
• between floors inside buildings;
• from an optical box or distribution frame to subscriber equipment;
• in locations with limited space for cable routing;
• in areas where additional mechanical protection of the optical fiber is required.

The patch cord can be used to connect ONU/ONT terminals, optical distribution frames, subscriber boxes, media converters, optical switches, and other telecommunications equipment.

Important: the armored construction protects the cable from mechanical impact, but the cable is not self-supporting and is not intended for aerial suspension between poles, supports, or buildings. For such installations, a dedicated self-supporting fiber optic cable with an appropriate strength member must be used.

Main specifications

Features of G.657.A2 fiber

ITU-T G.657.A2 is a single-mode optical fiber specially optimized for applications where small cable bending radii may occur. It provides lower additional optical losses caused by bending and is therefore widely used in modern FTTH subscriber networks.

This is particularly important when routing fiber optic cables in apartments, offices, cable trunking, telecommunications cabinets, and other locations where the cable route may include many bends and turns.

Features of the armored construction

The internal optical fiber is additionally protected by armoring elements, allowing the cable to be used in locations where a standard fiber optic patch cord could be damaged by mechanical impact.

At the same time, the compact 3 mm outer diameter makes the cable convenient for routing through cable ducts, trunking, and telecommunications cabinets.

SC-SC G.657.A2 Armored 3 mm fiber optic patch cord, 125 m, black — a practical solution for connecting subscriber and telecommunications equipment, combining enhanced fiber bend resistance with additional mechanical protection provided by the armored construction.
