Sterlite Tech’s two new airblown and micro cables launched at ANGA COM 2018 utilise existing and new duct systems to accommodate more fibres in a sub-duct network, allowing operators to implement high-density fibre counts within their existing cabling systems. Sterlite says the technology reduces deployment times for operators looking to meet global demands for 5G networks and FTTx. The company has also introduced a riser cable intended for FTTH in a vertical run shaft or inside buildings which meets industry standards for fire-resistance.
Sterlite’s airblown 2.6mm 24F Micro cable using 200 micron fibre technology can enhance airblown installations for FTTx drop deployments in congested areas and metro applications, also supporting installation in micro trenches along roads and pavements. Designed to provide an optimum balance of stiffness and flexibility, the cable can fit into limited 5/3.5mm ducts and reach longer blowing distances compared to other blown cables available in the market. Sterlite claims the 24F is the industry’s smallest multi-tube micro cable with easy drop and mid-span access and can be utilised for existing and new duct systems. Using compressed air in pre-installed micro ducts, the cable can accommodate more fibres in a given subduct and can be blown up to 2km for long distance links.
The 288F (24 x 12F) Micro Bullet series cable with standard 12 fibres per loose tube is claimed to be the smallest of its type on the market and is the latest addition to Sterlite Tech’s Bullet series. It is designed to re-engineer tube material for optimum cable packing efficiency – reducing approximately 10% of the cable weight and size, enabling up to 50% faster installation in a 14/18mm sub-duct, claims the company.
The indoor riser cable, which provides an easy deployment for riser applications in multi-storey buildings, complies with the industry CPR fire performance standards with classification B2ca-s1, d1. This cable allows set fibres to be broken out at floor level without the need to access the entire cable.
With enhanced features such as reduced sheath thickness and smaller loose tubes, the cables can be easily transported, managed and installed, significantly reducing deployment times. The cables, which leverage the latest industry standards and regulations, including ITU-T recommendations, also come in a range of sizes for different applications, providing greater flexibility and control within end blowing and mid blowing scenarios for extended lengths.
“As 5G-enabled services such as the IoT, Virtual and Augmented Reality and UHD/4K TV begin to grow, telecom operators and ISPs are looking for a fast and cost-effective way to significantly increase their fibre counts and enrich their fronthaul and last-mile networks to support these services,” says Dr Badri Gomatam, Sterlite Tech’s CTO. “This is no easy task; as the density of homes in urban areas increases, the current fibre architecture must evolve and advance at the point of consumption, as operators across North America and Europe look for innovative fibre cable solutions to maximise their existing fibre counts for global demands.”
