British optical fibres cables manufacturer UK

Tratos are an experienced international manufacturer and supplier of Fibre Optic Cables. Production of Optical Fibre Cables started in 1989, and since then, Tratos has invested in the latest technology, materials and human resources needed to meet the highest performance requirements in the field of all communication systems.

Tratos invest, on average, 7% per year in research and development on new equipment and new products.

Using Lucent OFS and Prysmian fibres, Tratos manufacture the complete range of Fibre Optical Cables used by BT (British Telecom), (NR) Network Rail and other National and International bodies.

TRATOS-FIBRE- CW1588-24F SECTION - optical fibres cablesThe Step Index single-mode optical fibre (SMF) fibres used to manufacture cables for BT meet or exceed the requirements for both Category 1 and Category 2 fibres as specified in CW 1505 for systems operating in the wavelength range of 1260nm to 1625nm. 

Step Index single-mode optical fibre (SMF) fibres are also used to manufacture cables in accordance with Network Rail Specification NR/PS/TEL/00014. And for demanding Naval applications such as Black Shark, the new generation of heavyweight torpedo

The Graded Index Multimode (50/125μm) optical fibres used by Tratos are optimised for operation in the 1300nm wavelength region and provide a specified transmission capability in the 850nm wavelength region, meeting or exceeding the requirements of CW 1504. In addition, these fibres comply with IEC60793-2-10 type A1a and also with categories OM1 to OM4 as defined in ISO/IEC 11801

All of the polymeric materials used in the construction of cables for BT meet or exceed the requirements of British Telecom Fibre Specification CW1500-7 or BS EN 50290 as applicable and are RoSH compliant.
All Tratos Aerial and Drop cables meet or exceed the operational requirements specified in BT Specification CW1500-11.

Tratos production of Optical Fibre Cables includes 1 single fibre to over 2,000 fibres in loose tube, ribbon, slotted ribbon, as well as composite hybrid copper and fibre cable.

All Tratos optical fibre cables for Internal use are available in LFH (Limited Fire Hazard) constructions.

Types of fibres

There are two basic types of Fibre

Type of fibre Description
MultimodeShort haul, high-capacity, applications inside buildings
Single-ModeLong haul applications but it needs expensive equipment

These two basic types can be broken down into

Type of fibreApplicationITU-T
Graded-Index MultimodeFTTHG.651.1
Standard Single-Mode CWDMG.652
Dispersion-Shifted Single-mode Long haul transmission G.653
Cut-off Shifted Single-mode Long haul submarine and Terrestrial G.654
Legacy Long Haul Single-mode CWDMG.655
Non-zero Dispersion CWDM & DWDM G.656
Bend-insensitive Single-mode FTTHG.657

  • ITU-T = International Telecommunications Union – Standardization sector
  • FTTH = Fibre to the Home
  • CWDM = Coarse wavelength division multiplexing
  • DWDM = Dense wavelength division multiplexing
Fibre designationsDiameterTypical performance
OM162.5 µm10 Gigabit up to 33 metres
OM250 µm10 Gigabit up to 82 metres
OM350 µm10 Gigabit up to 300 metres
OM450 µm10 Gigabit up to 550 metres
OM5*50 µm40 Gigabit up to 500 metres
OS29 µm10 Gigabit up to 40 kilometres

NOTE: Each fibre has its own unique characteristics and requires careful selection to ensure optimum compatibility with the detailed application.

Tratos Engineers have the knowledge and experience to advise customers and assist them with the selection of the most appropriate cable for their application

UK fibre optic cables

In the UK, fibre optic cables have become an essential infrastructure component for broadband and high-speed data transmission. The deployment of fibre optic networks has been pivotal in supporting the proliferation of high-definition streaming, online gaming, telemedicine, and the IoT (Internet of Things) ecosystem. Technically speaking, most of the fibre networks in the UK utilise Single Mode Fibre (SMF), predominantly G.652.D type, optimised for performance within the 1310 nm to 1550 nm wavelength range. Multi-mode fibre, typically of OM3 and OM4 types, is often reserved for shorter-distance applications such as in data centres.

The demand for faster and more reliable internet connections has driven many service providers to adopt the FTTP (Fibre to the Premises) model, ensuring direct fibre connections to homes and businesses. With FTTP, data rates of up to 1 Gbps and even 10 Gbps have been achieved, depending on the technology overlay. DWDM (Dense Wavelength Division Multiplexing) is increasingly utilised to maximise the capacity of long-haul and metro fibre networks by transmitting multiple wavelengths of light simultaneously through a single fibre strand.
