COMPONENTS AND SUBSYSTEMS Fibre-optic transceivers


Harting has developed a range of fibre-optic transceivers suitable for industrial applications by integrating electro-optical converters in small-form factor (SFF and SFP) packages with PushPull connector technology.


The company says the new devices have been developed in response to increasing demands for high-reliability optical communication devices that will withstand the harsh environmental conditions and vibration encountered in industrial applications, while offering simple handling and installation.


The transceivers are based on over-moulded Harting PushPull cable assemblies with LC duplex mating faces, and offer IP 65/67 protection and ease of handling. The easy-to-integrate PushPull device side allows fibre-optic devices to be added


RMT Boman series


New from Ridgemount Technologies is the RMT Boman series, which offers breakout manifolds of various sizes to accommodate different cable constructions and different fan-out tubes. They are ideal for pre-connection of both indoor and outdoor cables, the company says. They have been designed to ensure that a consistent product is manufactured with


LaserCleave


OpTek Systems has launched the second generation of its bench-top tool for termination of optical interconnects. The company says the LaserCleave is a compact, production-ready platform designed to maximise productivity in optical connector manufacturing. Central to the LaserCleave-1500 technology’s core value is the elimination of mechanical scribing, which is prone to fibre chips and hackle, and the reduction of

to existing solutions, such as I/O boxes, camera systems or industrial controllers. The transceiver module can be equipped with any SFF/SFP transceivers, and can be connected to the base plate via Harting har-flex connectors. www.harting.co.uk/connectors


a simple assembly tooling; fibre failures due to twist and tension are prevented, and performance is safeguarded. Applications include CATV and broadcast, data centre SANs, LAN ethernet networks and telecom networks. Ridgemount Technologies has more than 20 years’ experience designing and manufacturing fibre optic connectors. www.ridgemount.com


The ability to measure multiple sensing points over large intricate surfaces can be a difficult task. Traditionally engineers have used electrical strain gauges to monitor many points over a structure such as an aircraft wing or large composite component. However, applying many individual gauges is time-consuming and adds significant weight to the structure in the form of cabling. Fibre optic sensing techniques make this task easier by combining many sensors on a single fiber. However with the launch of the FBGS ‘All Grating Fiber’ it is now possible to position sensors adjacent to one another, making it possible to monitor changes throughout the complete structure and see how mechanical influences at one point can affect another. www.fbgs.com


H-206 alignment system


mechanical polishing steps that are used in the traditional finishing of connectors. OpTek says that elimination of operator variability in scribing, coupled with dramatic savings in consumable materials, labour and polishing equipment, leads to a direct reduction in manufacturing costs. Moreover the OpTek laser cleaving process is accurate and reproducible, improving first-pass yields and overall productivity. www.opteksystems.com


OPTICAL TRANSMISSION EQUIPMENT High Dynamic Range ICR


NeoPhotonics Corporation and Inphi Corporation have started shipping a new High Dynamic Range-Integrated Coherent Receiver (HD-ICR) in production volume to their customers. The HD- ICR couples the high dynamic range, low noise, and high input current handling capabilities of the Inphi IN3250TA TIA with the high sensitivity of the NeoPhotonics photodiodes, and is designed to deliver the performance necessary


for next generation 100G ‘colourless’ coherent transmission systems.


Colourless operation of 100G coherent networks is more efficient because add and drop ports are not limited to pre-determined wavelength channels, and any wavelength channel can enter or exit at any port. However, colourless operation places additional requirements on receiver performance, with up to 100 times more optical power falling on


the receiver than in the single channel if the remaining channels are not filtered out optically. For this case, NeoPhotonics has integrated a PIC variable optical attenuator that is designed to set the incoming optical power at the optimum point to avoid saturating the detector, while the high dynamic range and low noise of the Inphi IN3250TA enables the desired signal to be reproduced with high fidelity. www.neophotonics.com


PI (Physik Instrumente), a provider of precision alignment and motion-control equipment for photonics, nanotechnology and semiconductor applications, is offering a high-precision automated fibre alignment system with a controller and software. The company says the new H-206 alignment system can align fibres, collimators, fibre bundles and arrays quickly and efficiently.


It says the system has a high-performance


controller with optional photometer cards and built- in alignment algorithms, and gives up to 10 times higher throughput than conventional alignment systems. An optional piezo flexure scanner can further speed up the acquisition of a complete optical output profile of an optical device. www.physikinstrumente.com
