Fiber optic cable Alantec FTTH 2J B2ca SM 9/125 white, FRP strength member, all-dielectric, 1000 m

Alantec FTTH 2J B2ca SM 9/125 is a singlemode fiber optic cable designed for fiber-to-the-home and short-run building installations. The cable features a 2-jacket (2J) construction with 9/125 µm singlemode fibers, an all-dielectric design and an FRP (fiber-reinforced plastic) central strength member. The white outer sheath and B2ca flame performance rating make this cable suitable where low fire propagation and non-metallic construction are required. Supplied on a 1000 m reel, it is intended for indoor/outdoor use in risers, short external ducts and direct indoor routing where singlemode performance and low-smoke, low-flame properties are needed.

Advantages

The cable’s all-dielectric construction eliminates electrical conductivity and reduces the risk of corrosion or galvanic issues in mixed-material infrastructures. FRP strength member provides tensile support while keeping the cable lightweight. B2ca flame performance ensures reduced flame spread and limited contribution to fire load compared with lower-rated cables. A 9/125 µm singlemode fiber core supports long-distance, low-attenuation optical transmission and is compatible with standard FTTH connectors and splicing techniques. The 1000 m reel format minimizes joints and speeds up deployment for typical building and access network projects.

Suitable for

• FTTH drop and distribution lines in multi-dwelling units and single-family homes
• Indoor building risers and short external ducts requiring non-metallic cables
• Short-distance backbone runs between floors and equipment rooms
• Installations that require low fire propagation and minimal smoke generation

How to use

Route the cable along the planned path, avoiding sharp bends and maintaining the manufacturer’s minimum bend radius for singlemode fiber. Secure the cable in risers, conduits or on trays using appropriate non-compressive clamps or ties to prevent point loading on the fiber and FRP member. Prepare ends for termination or splicing using standard fiber stripping, cleaving and connectorization tools and procedures for 9/125 µm singlemode fiber. When pulling the cable, apply force to the cable sheath or designated pulling points and avoid directly pulling on the fiber core. Follow local building and fire codes when routing through protected shafts and penetrations.

Usage recommendations

For reliable long-term performance, observe minimum bend radii during installation and storage, keep fiber ends clean prior to connectorization or splicing, and avoid mechanical impacts that can damage the FRP strength member. Use suitable cable glands and fire-rated sealing for wall or floor penetrations to maintain B2ca performance in fire-resistant assemblies.
