      Description

      People are always amazed by the development of optical communication. Things move really fast in this industry. Fiber optic transceiver, a small-size but important optical component, can best represent the advancing of the optical communication industry. The form factor of optical transceivers has changed from GBIC for Gigabit Ethernet to SFP+ for 10GbE, QSFP+ for 40GbE and 100G CFP and QSFP28. Even a double density QSFP—QSFP-DD for 200/400GbE is under research. It’s not difficult to recognize all these different types of fiber optic transceivers. However, customer could be confused about how to connect these transceiver to the telecommunication network. This post will introduce how to select patch cables for optical transceivers in details.

      Patch Cable Selection Guide
      To select the right patch cable for your modules, you should firstly have a comprehensive understanding of the modules mainly from the following aspects: transmission media, interface, transmission distances and data rate.

            Description

            Although different methods for synthesising carbon nanostructures are available, research is still going on for finding the cheap and easy method for commercial preparation of different carbon nanostructures with controlled moiphology and high purity. The carbon soot obtained from burning of vegetable oils and animal based oils by using traditional method is found to contain carbon nanostructures including single-walled carbon nanotubes, multi- walled carbon nanotubes and carbon nanofibers. Carbon soot obtained by burning oils has been used as 'kajal' since ancient times. Kajal is easy-to-make by traditional method of flame deposition. It has been. found to contain carbon nanomaterials. Thus, synthesis of carbon nanostructures from vegetable oil using flame deposition method is studied in detail in regard to find a cheap source and easy method.

              DESCRIPTION
              Electro-optic tuneable filter consisting of a diffused channel waveguide on a borosilicate glass substrate with a cover of the same glass to form a gap filled with a holographic grating called POLICRYPS (POlymer LIquid CRYstal Polymer Slices). The grating is made of alternating stripes of polymer and liquid crystal. Coplanar electrodes on the waveguide substrate are used to electrically control the grating properties allowing for the filter tuneability.

              APPLICATION
              Broad band telecommunications and sensing systems.The market sector is photonic components.

              ADVANTAGES
              -Ultra-low value of electric power, in the range microwatts, required to drive the filter.
              -Extremely simple and cheap technology used to fabricate the filter.
              -The simplicity of the fabrication process can be easily implemented at industrial level for mass production

              INNOVATIONS FEATURES
              The use of low cost electro-optical materials which require low driving voltage and negligible current absorption hence the filter has low power consumption. Furthermore the fabrication is made of standard process steps to obtain a very low cost performing electro-optical component.

                Description

                DESCRIPTION
                The current invention provides a new approach for Circularly Polarized Luminescence (CPL) and Vibrational Optical Activity (VOA), Raman Optical Activity (ROA) spectroscopy that simplify the apparatus design, reduces the artefacts and enables simultaneous detection of the left and right circular component of the light out coming from the sample. The above-mentioned grating generates only the fields diffracted to the first order, whose amplitudes are proportional to the right and left circular components of the light beam impinging onto the grating. The method of the present invention demonstrates that, by using these characteristics of the grating, the chiroptical properties of a medium can be easily determined by sending the light beam coming from the sample to be analysed, onto the grating, and measuring the intensity of the beams diffracted by the grating.

                APPLICATION
                -The method is based on the use of a single element, other optical elements (polarizer, mirrors, wave plates, etc.) are not required, implying a reduction of the light losses and artefacts;
                -The method enables simultaneous measurements of the left and right circular components of the light at the exit of the sample.
                -The dispersion properties of the grating allow measurements in real time to be taken, in fact the signal at every wavelength diffracted at different angles can be detected in parallel by a photodiodes array or a CCD;
                -Monochromator and phase sensitive detector are not necessary;
                -Moving or time-modulated elements are not present;
                -Decrease of the production costs because it does not require optical and/or electro-optical elements as the standard systems do;
                -Performances enhancement, real time measurements due to the absence of moving elements, extremely simplified calibration procedures of the system;
                -Real time measurement implies the possibility to investigate dynamic processes;
                -The device can be integrated into multifunctional apparatus and is able for “in situ” measurements.

                ADVANTAGES
                It is a powerful spectroscopic method to probe of the structure and behaviour of biomolecules in aqueous solutions, including peptides, proteins, carbohydrates, nucleic acids and viruses.

                  Description

                  DESCRIPTION
                  The present invention relates to a method and a device to measure the circular dichroism exploiting a diffraction grating with proper polarization properties.
                  The grating generates first orders diffraction beams whose amplitudes are proportional to the left and right circular components of the incident light beam. We demonstrate that, exploiting this feature of the grating, the circular dichroism of any system can be easily evaluated measuring only the intensities of the first order diffracted beams, just locating the grating after the investigated system.

                  APPLICATION
                  Pharmaceutical, biological , cosmetic , food and environmental sector.

                  ADVANTAGES
                  -The method is based on the use of a single element, no other optical elements (prisms, mirrors, waveplates etc.) are required, implying low losses and reducing artefacts;
                  -No monochromator and phase sensitive detectors are required;
                  -No moving or modulated elements are present;
                  -No detection of the light beam intensity before the sample is needed since, exploiting the particular diffraction properties of the grating, the analysis is performed on the transmitted (diffracted) light beams;
                  -White linear polarized or rotating linear polarized or depolarized light can be used,
                  -The dispersive properties of the grating allow to perform real time measurements, since the signal at any wavelength is diffracted at different angles from the grating and can be revealed in parallel by a photodiode array or a CCD;
                  -The previous described properties allows to investigate dynamical processes;
                  -Complex and repetitive calibration procedure are not required;
                  -Small size , the device can be used for “in situ” measurements and integrated into in-line instruments;
                  -Compact device allow to made a portable version of the instrument;
                  -Reduction of the production costs.
