iXblue: pioneer in Optical Reference Transmitter solutions
The Optical Reference Transmitter (ORT) ModBox is a flexible and efficient electrical to optical converter. The ModBox can be optimised to generate linear or digital standard telecommodulation schemes such as NRZ with and without adding impairments, DPSK, QPSK, QAM, PAM-4 up to 56 G. ModBox addresses the telecommunication and network equipment markets. It is designed for high-speed test solutions that are robust, reliable and compliant with IEEE standard. The ORT ModBox is a tool for the development and characterisation of the next- generation telecommunications components for datacom, long-haul and other optical interfaces. Indeed, the ModBox can be used as a golden optical transmitter or as a tool to simulate network impairments in applications such as TIA and receiver testing in R&D or automated testing environments, network Electron Beam Lithography (ELB) has proven to be a perfect manufacturing method to realise complex DFB laser diode structures containing single or multiple phase shifts, continuously varying line widths or chirped gratings. Raith’s Voyager and EBPG series offer a solution to tackle the challenges DFB laser makers are usually facing. First of all, they are flexible and a new design or a different pitch can immediately be transferred from (CAD) design to production. Furthermore, they are reliable. As a market leader for Gaussian Beam systems hundreds Malfunctions or failures in optical backbone networks are the nightmare of any network operator and can result in nerve-wracking and often costly repairs. For this reason, reliable connectors with consistent optical performance under varying environmental conditions are critical to the operation and performance of backbone systems. Every lost photon heats the system unnecessarily and thus reduces component reliability. Insertion loss, return loss and the ability to withstand high power densities are decisive criteria that should be considered when selecting the suitable connector. For more than 30 years, the Swiss company
components and devices characterisation. For optimal performances, a default CW laser is embedded to ensure a high quality optical modulated signal (high and stable optical power, with low jitter, high SNR, fast rise and
fall times, eye diagram). Also, iXblue offers a wide option of lasers for integration with a full O-Band solution integrating up to four lasers at the CWDM channels and tunable C and L-band lasers.
Electron Beam Lithography for DFB laser manufacturing
of Raith EBL machines are installed in the field, with many of them operating 24/7 in industrial environments. The EBPG series tools additionally eliminate all operator interference from wafer loading to unloading. With the fully automated processing, repeatable and advantages that come with Raith’s unique Modulated Beam Moving Stage Technology (MBMS). MBMS enables the writing of stitch- free, strip-shaped periodic structures. During the patterning process of the substrate, the accurate results can be achieved. Speed and precision are two more Diamond SA, has increasingly specialised in developing and manufacturing high-quality connectors for a wide variety of applications. As a vertically integrated company, all products are consistently manufactured in Switzerland and tested using controlled processes and only high-quality materials. Diamond SA has also developed various technologies that are unrivalled worldwide and therefore guarantee unparalleled transmission quality. For example, Diamond SA’s Active Core Alignment (ACA) core centring technology minimises fibre ferrule concentricity down to the reference level. During this process, the end face is deformed after the fibre has been polymerised in place,
supporting stage is moved continuously along a predefined path. This method maximises throughput by minimising the overhead time of the patterning process. At the same time, the level of pitch control accuracy is increased significantly to the range of around 0.01 nanometres. Even complex structures such as phase shift gratings can be fabricated in this way. Raith’s Voyager and EBPG series are both equipped with everything needed for the development, prototyping and manufacturing of DFB lasers or other telecom devices. in order to centre the fibre core with the mechanical axis of the ferrule. Like the Diamond E-2000 connector, the F-3000 contains many of the same product features making it ideal for critical backbone applications. In addition, an automatic metal cover provides reliable protection against contamination. Furthermore, the F-3000 has recently been standardised as an LF3 connector
