New Marketing Positions at Fibercore Ltd

Following our divestiture from the Cisco group, and the very successful completion of Fibercore's first full year as an Independent Company, we are expanding our Sales and Marketing Department and are recruiting for the following two new posts:

Company Marketing Executive

An exciting opening has been created for an experienced marketer to join Fibercore Limited in the new role of Company Marketing Executive.  Although the position will be supported by a full-time Marketing Assistant, this is a very hands-on role that will give you the opportunity to lead a major re-branding exercise and to develop the new marketing strategies, particularly within the digital sphere, that will spearhead Fibercore's plans for strong and continued business growth.  Reporting directly to the Chief Executive, the successful candidate is likely to be degree-qualified, with relevant post-graduate qualifications in marketing and/or business.  A born communicator, you will also have a strong awareness of and affinity for Science and Technology and the proven ability to create a broad range of high-quality, technical marketing collateral.  Experience of managing external agencies (Creative, PR, etc), websites and CRM databases, and the organisation of international tradeshows and events are also essential - as is a true passion for Marketing.  The position carries a competitive salary and an exceptional benefits package.

Marketing Assistant

The expansion of Marketing at Fibercore has created a rare opportunity for a recently-qualified marketing professional to gain international experience across a broad spectrum of both traditional and digital marketing activities.  Reporting to the Company Marketing Executive, you will assist in a major, re-branding project encompassing the build of a new website, creation of new literature, development of a digital strategy and all associated communications.  Day-to-day activities will include helping in all aspects of the organisation of international trade-shows, from booking floor-space, organising hotel accommodation for attendees, through to pre- and post-show promotion, participation in lead-generation activities, management of the CRM and updating of the website.  You will most likely be educated to degree level with a professional qualification in marketing or business.  You will also be able to demonstrate a strong interest in Science and Technology and the ability to understand and communicate complex concepts in a clear and simple manner.  The position carries a competitive salary and an exceptional benefits package.

Fibercore Limited is a market leader in the field of 'Specialty' Optical Fibers.  Originally a technology spin-out from the University of Southampton, now celebrating its 30th year in business, the Company exports over 95% of its production to around 50 countries Worldwide.  Its innovative products are used in a diverse range of industrial sectors including Aerospace, Telecommunications, Energy and Fundamental Research - and have been deployed quite literally from Southampton to Mars!  Growing demands and ambitions for growth mean that we need exceptional individuals to head up and assist in formalising Communications and lead-generation.  If this sounds like you - then Fibercore Ltd wants to hear from you.

To apply for either position, send your cv and covering letter to: HR@fibercore.com or write to:

Inertial Sensors and Systems - Symposium Gyro Technology 2012

HiBi Single Polarizing HB-Z Zing™ Fibers for Fiber Optic Gyroscopes

0930 hrs Day 2: Wednesday 19 September 2012

Jose Alvarez will be discussing the use of HB-Z Zing™ fibers in FOGs in the second of our two papers at this Show.  Introduced in 2010, continual development now enables us to offer two new variants for operating at around 830 nm and 1310 nm, in addition to the original HB1060Z . 

Over the last few years the Inertial Navigation System (INS) industry has experienced an increasing demand in the accuracy of the gyroscopes for new military, space and civil applications. In this sense, setting and controlling the polarization state of the light launched into the fiber coil is a critical issue when designing a high precision Fiber Optic Gyroscope (FOG).

Traditionally, LiNbO3 multi-funtional integrated optical chips (MIOCs) have included the polarizing functionality in the gyro along with the splitter and the modulator, with different results in performance, cost and resilience.  The complexity of including the MIOC in the FOG design, and its high impact in the total cost of the gyroscopes, have created many problems to the FOG manufacturers. To support the industry, Fibercore have designed a new range of polarizing Zing™ fibers that will bring an all-fiber passive solution to this problem in terms of reduced cost, compact packaging, low insertion losses, power consumption, reliability, etc. 

A polarizing fiber guides the light in just one axis of the transmitted mode, cancelling the orthogonal degenerated mode by means of bending losses due to its extremely high birefingence levels.  This high birefringence (represented by a beat-length of about 0.6 mm @ 633 nm) creates a different refractive index and therefore a different propagation constant for the light traveling on both fast (lower refractive index) and slow (higher refractive index) axis. Therefore the bend edge of both axes will be clearly separated and, at some point, the fiber will guide the light in just one of the axes allowing for a stable single polarizing window of 100 nm - 200 nm with higher than 30 dB PER levels. To encourage this behaviour, the fiber will operate far away from the cut-off region and the initial NA of the fiber will be as low as possible so the polarizing effect is much more noticeable.

A theorectical explanation, based on the bending loss equation, of the basic operation and design principles of these fibers will be given in the paper.  The benefits of an all-fiber solution over other alternative technologies will be discussed along with significant experimental results showing the performance of the Zing™ fibers under different deployment and system conditions.

Inertial Sensors and Systems - Symposium Gyro Technology 2012

Radiation Tolerant Optical Fibers for Fiber Optic Gyroscopes

1600 hrs Day 1: Tuesday 18 September 2012

Fibercore Ltd has long been associated with fibers for FOG applications and our fibers are used in many different environments, each environment presenting its own unique challenge.  In the first of our two presentations at this year's Symposium in Karlsruhe, Dr Andy Gillooly will be discussing the challenges that space applications present and how they are overcome. 

The application space for Fiber Optic Gyroscopes (FOGs) has been constantly growing with many applications in ground based vehicles, marine and aerospace sectors. As the FOG technology matures and gains better acceptance the use of FOGs in high value projects, such as satellites, continues to grow.  TV channel broadcasting drives the growth of the satellite industry and with momentum behind the lower cost micro-satellites there will be many new opportunities for the inclusion of FOGs into future satellite projects.

For most FOG fiber coils, polarization maintaing (PM) highly birefringent fibers are used which have an inner cladding region made from phosphorus doped silica.  The addition of phosphorus into the inner cladding aids the manufacturing process and is suitable for most terrestial applications. However with exposure to radiation, the phosphorus causes the attenuation of the fiber to increase.  The rate of attenuation increase is relative to the radiation dose and the operating state of the fiber.  Therefore PM optical fibers which are to be used in space applications or other applications that require radiation resistance need to be designed without phosphorous.

The effect of radiation on erbium doped fibers will also be discussed to give a balanced view on the possibility of using erbium doped fibers as ASE light sources for FOGs in radiation environments.  The radiation causes a change in the spectral response that is not constant over the full spectral range of the absorption and emission of the erbium doped fiber.  The level of spectral change is relative to the type and concentration of dopants used within the fiber, giving significant constraints in the ability to design an erbium doped fiber suitable for space applications.

The theory will be analysed and discussed and experimental results will be shown comparing the performance of phosphorus doped and phosphorus free PM fibers before and after exposure to radiation and the effects on erbium doped fibers will also be measured and discussed.
