This duplex fibre optic zipcord cable features two 200 µm Hard Clad Silica (HCS) fibre cores inside an orange 2.5 mm low-smoke zero-halogen jacket. It is purpose-built for indoor industrial environments where fire safety and reliability are critical. The LSZH construction helps minimise smoke and avoids toxic halogen gas release under fire exposure, making it suitable for enclosed installations and safety-sensitive sites.
Its large-core step-index design supports simple crimp-and-cleave field termination with compatible ST or SMA connectors, without epoxy or polishing. Aramid yarn strength members and a durable construction help the cable withstand high installation loads and repeated flexing. With attenuation of up to 6 dB/km at 850 nm, it provides dependable optical performance for typical industrial link distances. The cable is rated for indoor use and operates from -20 °C to +80 °C. Overall, it is a robust, low-maintenance fibre solution for industrial communication and control systems.
The C21051 is a duplex zipcord fibre optic cable built around two 200 µm Hard Clad Silica fibres in a 2.5 mm LSZH construction. It is designed for indoor industrial environments where reliable optical performance, fast field termination, and improved fire safety are essential.
Its zipcord format keeps both fibres neatly paired for duplex links while allowing easy separation during connectorisation. The cable is especially well suited to enclosed or high-risk installations such as power facilities, offshore platforms, marine systems, and other industrial sites requiring low-smoke, halogen-free materials.

FAQs
for Zipcord 2.5 mm LSZH Cable 200 µm HCS® Fibre for Crimp and Cleave
Hard Clad Silica (HCS) fibre uses a silica glass core with a hard polymer cladding. In this cable, the 200 µm HCS design provides a strong balance of durability, manageable handling, and optical performance. Its larger core also simplifies alignment and supports practical field termination compared with standard telecom fibre.
The LSZH jacket is chosen to improve fire safety in enclosed indoor environments. If exposed to fire, it produces very little smoke and does not release halogenated gases, helping reduce risk to people, equipment, and visibility in critical spaces.
This cable is designed for crimp-and-cleave field termination using connectors intended for 200 µm HCS fibre, typically ST or SMA types. These connectors allow quick installation without epoxy or polishing.
No. This product is specified for indoor use only. It does not include the UV resistance, water blocking, or outdoor protection features typically required for exterior or direct-burial installations.
The specified attenuation is ≤ 6 dB/km at 850 nm. This makes it well suited to typical in-building and industrial optical runs where dependable short-to-medium distance transmission is required.
Zipcord means the cable consists of two parallel fibre sub-units joined together in a duplex format. This keeps both fibres organised during routing while allowing them to be easily separated for individual connector termination.
The cable is built for demanding industrial handling. It supports installation loads up to 734 N, has a flex life of more than 50,000 cycles, and specifies minimum bend radii of 38 mm during installation and 25 mm during operation.
