Unitube fibre optic cables

APAR’s optical fibre cables have several optical fibres bundled together, which are then individually and protectively covered to reduce losses and damage.

Fibre optic cables use light pulses to transfer data signals up to hundreds of miles and they have a higher bandwidth and throughput than conventional electrical communication cables. In today’s advanced environment, fibre optic cables are the main source of communication between organisations with multiple sites, telecom companies, and many other such long distance communication applications that require higher bandwidth and longer distance transmission. The type of optical fibre to be used is dependent on the application, the distance which the signals are required to travel, and the speed of transmission. The installation and environmental requirements also decide the cable construction. This includes (but is not limited to) indoor applications within a dry wall in a public area, which may or may not have special LSZH materials, and installations along railway tracks. APAR’s customised cable solutions cater to the high-bandwidth applications of data centres, global internet companies, ISPs and telcos, and citizen network services.

Breakout tight buffer optical cables

These cables are made by bundling tight buffered simplex fibre optic in an outer jacket. Non-metallic, FRP-strength members in the cable give it good tensile strength and electromagnetic protection.

The cables have a small diameter, and a lightweight and thick-walled jacket protection to allow for versatile applications. They are used in cable assemblies and in places of high electro-magnetic interference. Each fibre is mechanically reinforced with two successive sheaths of 400μm and 900μm, enabling direct termination of connectors. They are available in PVC, LSZH or plenum outer sheath and a tight buffer: 900μm, 600μm.

Application	These cables are meant for indoor use. They are specially designed for applications like floor distribution, interconnection and equipment.
Characteristics	Excellent strip force stability, fibre-geometrical dimensions and good transmission performance are some of the characteristics of this cable. Tight-buffered cables are also easier to install because there is no gel to clean up and they do not require a fan out kit for splicing or termination. Connectors can be crimped directly to each fibre.
Applicable standards	ITU-T G652.B OS1; ITU-T G652.D/G655/G657.A1/G657.A2 OS2; ITU-T G651.1 OM1 OM2 OM3 OM4IEC60793-2-10 type A1a.1/A1b OM1/OM2; IEC60793-2-10 type A1a.2 OM3; IEC60793-2-10 type A1a.3 OM4ISO/IEC 11801 , ISO/IEC 24702; IEEE 802.3z Gigabit Ethernet; ANSI/TIA/EIA 568C.3; ROHS-compliant directive 2002/95/EC ; LSZH: IEC 60332-1, IEC 60754, IEC 61034

Ribbon cables duct, armoured & aerial

Ribbon optical cables are used for duct, direct buried, and aerial installations. These cables have a specific design of water block yarn that helps eliminate the steps associated with standard gel-filled cables.

This is a stranded loose tube cable with optical fibres placed inside robust buffer tubes stranded around a fibre-reinforced plastic (FRP) central strength member.

In addition to optical fibres, the buffer tubes contain water-blocking gel and the cable core is surrounded with a water-swellable tape to prevent water ingress in the interstices of the cable core. Glass roving yarns are distributed over the inner sheath, and a thermoplastic jacket provides the cable with both mechanical and environmental protection.

Application	Ribbon optical cables are intended for duct, direct-buried, and lashed aerial installations. These cables are used for fibre networks where a high fibre count is required. Ribbon fibre optic cables can be used in indoor FTTH networks and indoor/outdoor point-to-point applications.
Characteristics	These cables are lighter compared to the old gel-filled cables. This allows for easier cable handling, easy mid-span entry, and superior fibre access.
Applicable standards	IEC 60793, IEC 60794, Telcordia GR -20, TIA/EIA 598
Product range	From 4F fibre up to 1000 single mode fibres in full compliance with ITU-T-G.652.D in 4/6/8/12 fibre ribbon (also available with G655 / G656 / G657 SM Fibre and OM1 / OM2 / OM3 & OM4 MM Fibre). These cables can be provided with unarmoured ducts for underground applications, ADSS for aerial use and armoured cables for direct buried applications.
Advantages	These cables are more installer-friendly, and lighter in weight than conventional gel-filled cables, and hence allow for easier handling, mid-span entry, and provide superior fibre accessibility. The first advantage of a ribbon fibre jumper is the ability to save time and reduce installation cost. Since the cables are pre-banded (usually made up of 12 sets of separate fibres), installers and technicians can perform simpler, faster mass fusion stitching so that all fibres in the ribbon matrix can be stitched together at the same time. This means less installation time, lower installation labour costs, and faster recovery during downtime.The second benefit of the ribbon fibre cable is the increased fibre density of the cable. Fibre density is an important benefit as it increases the fibre count at the data centre.

ADSS and fig 8 aerial cables

ADSS Cables are lightweight with a small diameter, which enables them to be installed aerially in short, medium or long distance applications.

The construction consists of a uni/loose tube cable with an optical fibre placed inside buffer tubes which are then stranded around a fibre-reinforced plastic (FRP)-strength member at the centre. In addition to fibres, the tubes contain gel to block water and prevent it from entering the gaps in the cable core. A water-swellable tape is also provided around the cable core. Strong, evenly distributed aramid/glass yarns provide the tensile strength required in aerial self-supporting applications. To give mechanical and environmental protection, a thermoplastic overall sheath is also provided with the cable. This is a metal-free cable specially designed for laying below high-tension power lines ranging from 11 kV to 660 kV. For above 33 kV power lines, a special anti-track material is used, to prevent dry band arching on ADSS cables and to save cables from damage.

For Figure 8 aerial self-support cables, the upper part of figure 8 has messenger wires (1 X 7 Stranded GI wires) with a PE outer sheath. The aerial messenger strand portion of the Figure 8 cable supports the mechanical and environmental stresses on this cable. Its strength-to-weight ratio allows it to support the composite strand/cable between poles (or support structures) protecting fibres from stress and sagging. This cable is suitable for hilly regions where a pole is difficult to use. However, this cable cannot be used under high tension lines.

Application	This ADSS Cable is designed for outside plant (OSP) aerial self-supported applications, high-tension power line distribution and local and campus network loop architectures. The cable is suitable for aerial-to-duct/underground transitions. Figure 8 cables are suitable for aerial applications.
Characteristics	This cable can be designed to specific requirements of length, wind speed and other loading conditions. All dielectric designed cables are completely immune to electromagnetic fields.
Applicable standards	IEC 60793, IEC 60794, Telcordia GR -20, TIA/EIA 598, IEEE 1222
Product range	APAR offers ADSS Cables from 2F to 288F or more as per customer specifications, with various types of fibres like G.652 D, G657A1 & A2 ,G.655, G.656.

APAR offers a variety of Figure 8 aerial cables from 2F to 288F, with single and multimode fibres, with uni/loose tube unarmoured and armoured cables.
Advantages	These cables are flexible, lightweight, easy to handle and install. They are tensile, crush resistant and UV protected. The physical parameters of these cables are tightly controlled. All-dielectric self-supporting (ADSS) fibre cables provide advantages over strand and lash fibre networks for electric utility applications in many cases. Some of the advantages of ADSS cables include: No metallic components. They can be installed in supply space with no grounding required Little to no ‘make ready’ cost Lower hardware costs Speed and ease of installation Minimal long term maintenance Longer expected design life In most scenarios, these advantages lead to lower total cost for the electric utility.

Single-mode and multi-mode fibre

Single-mode fibre optics have a small diameter core, which allows only one mode of light to propagate. Multi-mode optical fibres are about 10 times bigger than single-mode fibres.

Single-mode fibres have a very thin core, with a diameter of 8-10 microns for the optical signal to move through. The light signal follows the principal of total internal reflection, and passes through the fibre core throughout the fibre length at the speed of light. Due to lowered attenuation, the signal can travel faster and farther. A single-mode fibre cable is suited to long distace networks, such as from one city to another, one state to another, or even one continent to another.

Multi-mode optical fibres are about 10 times bigger than single-mode fibres. They allow light beams to travel in a variety of paths (hence the name multiple modes). Multi-mode fibre optic cables have a large core diameter to allow multiple modes of light. Due to multiple modes of light travelling within the fibre, dispersion and attenuation is higher than in single mode fibres. A multi-mode fibre cable is suitable for small distance applications such as local area networks, transmission from one complex to another, one machine to another, and for indoor use.

Application	Single-mode fibres are meant for long distance data transmission networks (100 kms and above) due to their enormous bandwidth and low losses. They are generally used by telcos, CATV companies, railways, power grids and oil and gas companies. Multi-mode fibres are typically meant for short distances (maximum 2 kms) and are generally used in data and audio/video applications in local area networks.
Characteristics	Large ﬁbre counts with small cable diameter. These cables are highly adaptable to mass splicing and are suitable for installation in pipelines.
Applicable standards	IEC 60793, IEC 60794, Telcordia GR -20, TIA/EIA 598
Product range	APAR offers single-mode optical fibre cables using G652D/G655 & G 657 fibres from 2F to 512 F, in armoured, unarmoured and aerial appliications. Multi-mode optical fibre cables using OM1/OM2/OM3 & OM4 fibres from 2F to 24F, in armoured, unarmoured and aerial applications.
Advantages	Single-mode fibre optic transmissions are faster than multi mode over long distances, because fewer switches or routers are needed mid span. They have virtually unlimited bandwidth, and are capable of transmitting data at up to 40 GB over hundreds of kilometers, with little integrity loss. Multi-mode cables are less expensive to install, operate, and maintain. Multi-mode cables have high speed and high bandwidth over short distances. They allow several mode optical signals to be transmitted at once.
