Created from BGBs constant passion for innovation and development, BGB Telemetry is BGBs third sub brand, replacing the former brand Digilinc (Digilinc can now be found under the BGB Marine brand). Born through Research & Development, BGB Telemetry’s main product offering comes through the highly successful Fibre Optic Rotary Joint (FORJ) – Optilinc. As Optilinc continues to open new markets and applications, it was decided that Optilinc needed its own specific “contactless” brand identity instead of sitting under the general BGB Engineering brand. As well as Optilinc, BGB Telemetry opens the way for further innovations such as induction, capacitives and other contactless methods of transferring power, data and signal through rotary applications.

Optilinc - Standard Fibre Optic Rotary Joint (FORJ)

The BGB Optilinc system has been produced to revolutionise the slip ring market. Optilinc is the first of the new generation of contactless slip rings to be produced by BGB. The fibre optic rotary joint (FORJ) is ideal for high speed data- transfer within many applications. Constructed in stainless steel, Optilinc has exceptional durability protecting the unit from dust and water ingress to IP68 (dependent on fibre and connection system) and is not influenced by vibration, humidity, heat, magnetism or other typical disturbances.

*Standard FORJ with Flange Mount & ST Connector

Optilinc is available with either ST or RSC connections and designed for either Singlemode or Multimode. Optilinc has been rigorously tested by Deutsch UK Ltd to EN2591-601, (Aerospace series - Elements of electrical and optical connection Part 601: Optical elements - Insertion loss) and to EIA standards. Optilinc is currently being implemented within leading global wind turbine manufacturers and has been successfully used in other industry applications such as centrifuges, rotating media displays, wastewater, radar systems and ROVs around the world.

Slip Ring Assemblies with FORJ

BGB can build all Optilinc products into bespoke slip ring solutions incorporating connections to suit each individual requirement. Data transfer would not be vulnerable to electromagnet interference from high frequencies. Slip ring assemblies with Optilinc for data would also not be susceptible through data loss due to low resistance contact on an infrequently used low power data ring.

Key benefits: • Minimal wired connections

• Minimal torque • Easily serviced

• Complete packaged solution • Tried and tested in the wind industry • All encased in an IP rated enclosure • Adaptable to all environmental conditions • Immune to all forms of electrical interference (Optilinc FORJ) • Future proof - if bandwidth needs increasing in future, electronic components can be changed easily

BGB's new capacitive range, Capacilinc, is a selection of contactless data transmission systems for use within any hi-tech industry. The contactless data transmission channel offers improved lifetime and reliability without the need for maintenance. The contactless design guarantees error free data transmission even at very high rotating speeds. The IRT version supports Profinet class C and other real time protocols. The data transmission channel is realised by a rotating capacitive coupler. Industries already using capacitive technology include: Wind power, Construction, Military, Stage Technology, non-destructive material testing systems and Medical.

Media Converters

Fibre media converters are simple networking devices that make it possible to connect two dissimilar media types, such as twisted pair with fibre optic cabling. They were introduced to the industry nearly two decades ago and are important in interconnecting fibre optic cabling-based systems with existing copper-based, structured cabling systems. Fibre media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/ J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fibre optics.

Media converter types range from small stand alone devices and PC card converters to high port-density chassis systems that offer many advanced features for network management. Other benefits of media conversion include providing a gradual migration path from copper to fibre. Fibre connections can reduce electromagnetic interference. BGB Media converters can now be produced to enable multiple ethernet connections and built in switches.

Wavelength Division Multiplexers

Wavelength Division Multiplexer (WDM) systems are popular with

telecommunications companies and some pitch control manufacturers. WDMs allow these companies to expand the capacity of the network without laying more fibre. By using WDM and optical amplifiers, they can accommodate several generations of technology development in their optical infrastructure without having to overhaul the backbone network. Capacity of a given link can be expanded by simply upgrading the multiplexers and demultiplexers at each end.

This is often done by using optical-to-electrical-to-optical (O/E/O) translation at the very edge of the transport network, thus permitting interoperation with existing equipment with optical interfaces.

Most WDM systems operate on single-mode fibre optical cables, whereas Optilinc is designed to operate on both single and multi-mode.

Wavelength-division multiplexing (WDM) technology in the LAN is especially beneficial in situations where fibre is in limited supply or expensive to provision. As well as conventional dual strand fibre converters, with separate receive and transmit ports, there are also single strand fibre converters, that can extend full-duplex data transmission up to 70 kilometres over one optical fibre.

Wavelength Division Multiplexers

The new BGB Wavelength Division Multiplexer (WDM) has been designed to compliment the BGB Optilinc FORJ (Fibre Optic Rotary Joint) to convert two fibre (duplex) systems to a single fibre multiwave length system (simplex).

Its unique rugged design has been developed to adapt itself to all environmental conditions. Designed to survive the arduous [physical and electrical] environments found in the wind energy industry (which insist on inbuilt transient surge protection), the WDM protects itself from lightning strikes via inbuilt electronic clamping systems. When combined with BGBs Optilinc, the WDM lends itself to all applications whether it be light or heavy industry. Available as a 100Mb or GigaBit converter.

Advantages of Fibre Optics

Why are fibre-optic systems revolutionising the market? When compared to conventional metal wire (copper wire), optical fibres are:

• Thinner - Optical fibres can be drawn to smaller diameters than copper wire. • Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires. • Less signal degradation - The loss of signal in optical fibre is less than in copper wire. • Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. • Low power - Because signals in optical fibres degrade less, lower- power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. • Digital signals - Optical fibres are ideally suited for carrying digital information. • Lightweight - An optical cable weighs less than a comparable copper wire cable. Fibre-optic cables take up less space. • Flexible - Because fibre optics are so flexible and can transmit and receive light, they are used in many flexible digital cameras for the following purposes: • Medical imaging - in bronchoscopes, endoscopes, laparoscopes

• Mechanical imaging - inspecting mechanical welds in pipes and engines (in airplanes, rockets, space shuttles, cars)

• Plumbing - to inspect sewer lines
