INTERCONNECTS Electro-optical convertors feature push-pull connector technology Harting has developed a new 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 transceivers are based on overmoulded Harting PushPull cable assemblies with LC duplex mating faces, and offer IP 65/67 protection and ease of handling. The easy-to-integrate Push- Pull device side allows fibre-optic devices to be added 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. Harting www.harting.com Single chip enables DisplayPort, USB and power over a single cable Texas Instruments has launched a single chip that delivers audio/video, USB data and power over a single cable between a notebook, ultrabook or tablet PC and a docking station or dongle. DockPort provides a lower cost alternative to proprietary implementations and offers more features than standard USB docking stations. It enables system designers to create smaller, more affordable docking stations that connect and synchronize computers with LCD monitors, dongles, keyboard/mouse, Gigabit Ethernet, storage, audio speakers, DVD/Blu-ray media player and smartphone. The HD3SS2521 controller enables DisplayPort, USB 3.0, USB 2.0 and power over a single interconnecting cable, and provides the control logic and automatic switching required on the cable’s host side and dock side. The HD3SS2521 enables system designers to create smaller, more affordable docking stations that connect and synchronize computers with LCD monitors, dongles, keyboard/ mouse, Gigabit Ethernet, storage, audio speakers, DVD/Bluray media player and smartphone.A bidirectional 2:1 switch manages DockPort detection, as well as signal and power switching. It enables display, USB, power, and computer docking Interface over a single cable, which allows designers to create smaller, more affordable docking stations. The 5x11mm package reduces board space by one-third and BOM costs by more than 50% compared to competitive implementations that provide data and A/V over a single connector. Power and charging is delivered over the same cable, reducing the number of connections by allowing upstream charging of host-side computers, or downstream powering of one or more dongles. Operating in two-lane mode with USB 3.0 data, the HD3SS2521 supports one monitor with resolutions up to 4K2Kp at 30 frames per second (fps) and 30 bits per pixel (bpp), or multiple monitors with resolutions less than or equal to 1920 by 1200p at 60 fps. Texas Instruments www.ti.com Device cleans MPO/MTP connector end-faces Fujikura Europe has released the One-Click Cleaner MPO designed specifically for cleaning MPO/MTP connectors and adapter mounted MPO/MTP connectors which are widely used in data centres and also in some telco operated infrastructures. The new product cleans MPO/MTP connector end-faces which have been exposed to loose contaminants, such as dirt and oil from an installer’s fingers. With just one simple action it is able to clean a variety of fibre counts up to 48 fibre MPO/MTP end faces and is capable of providing over 500 cleans per unit. The One-Click Cleaner MPO is now included within a range of tools which are designed and built to clean an array of network connections. It has also been produced to be more ergonomic than the previous design of MPO cleaning tools by Fujikura. The cleaner is compliant with the EU/95/2002/ EC directive (RoHS) since it is made of environmentally friendly materials. An adapter/dust cap is also supplied with the product for cleaning MPO/MTP connector plugs as well as the connectors themselves. Fujikura Europe www.fujikura.co.uk Silica-based optical fibres and hollow silica waveguides Polymicro Technologies, a subsidiary of Molex Incorporated, has extended its specialty optical fibre offering with the introduction of FBPI optical fibre and hollow silica wavelength fibre products. Optimised for near infrared (NIR) attenuation and ultraviolet (UV) solarisation resistance to improve transmission over a wider spectral range, the Polymicro silica-based FBPI optical fibre delivers panoramic spectroscopy and sensor analysis. Available in a range of core diameters from 50-600 μm, broad spectrum FBPI optical fibre with a low -OH pure silica core demonstrates significantly reduced content of UV defects and other UV absorption centres. In the nearinfrared (NIR) wavelength region to beyond 2100 nm, Polymicro FBPI fibre attenuation is equivalent to standard NIR fibres having a low -OH silica core and F-doped cladding. Comparable to solarisation properties of standard UV optimised high -OH fibres with high radiation resistance, FBPI fibre features UV transmission down to 200nm. Strong and flexible Polymicro hollow silica wavelength fibre for CO2 laser delivery can be optimised for wavelengths in the infrared region from 3-20 μm for a range of applications, including replacement for high cost, heavy, rigid articulated arms in medical and dental laser applications, industrial cutting, and laser printing and marking. Enabling high laser power delivery under 100W, the hollow construction silica simplifies end termination, reduces abrasion and provides a robust buffer in harsh environments. The geometry of the biocompatible fibre can be easily changed to accommodate part customisation. Available with custom buffers, HSW fibre features removable, reusable Poly-Lok Connectors for prototyping.
