to 25 km. The entire solution is fully passive and does not require chromatic dispersion compensators. Optical modules can also be installed directly in network devices such as routers or switches.
Lower CAPEX and OPEX Compared to DWDM solutions, we eliminate 10 ~ 20W amplifiers and a 40 ~ 150W chassis on each side of the transmission line. Additionally, compared to coherent technology, we eliminate the need to use transponders/muxponders and grey optics to make connections between network devices. Such a procedure allows operators to reduce electricity consumption by up to 80 per cent.
locations. The duplex system uses the same wavelength for transmitting and receiving, carried by different fibres. However, in the case of implementing such a system
using one optical fibre, we use two different wavelengths, one for transmission and one for receiving. This way, the number of services we can run is reduced by half.
Thanks to O-band technology, we can increase the capabilities of a pair of optical fibres by running up to 16 x 100GbE on them. This system can provide services up
O-band solutions provide an easy and economical method for migrating to 100Gb/s and it’s dedicated for access and mobile base station uplink network. Using multiplexers and modules based on O-band allows operators to cover distances of up to 30 km, while maintaining their required passive infrastructure for easier management and lower energy consumption.

White paper sheds light on the challenges and solutions when using optical sensors
I
n many manufacturing applications object detection commonly deploys optical sensors because when compared to other types of sensors, they provide the important benefits of precise, non-contact detection at very short response times across both long and short distances. Also, compared to other types of sensors they are extremely compact, so require minimal space.
However, there is one crucial drawback with light barriers and photoelectric sensors. This is because they operate on ambient visible light of the same spectral range as artificial light or sunlight, so are susceptible
to detection errors. Furthermore, most sensing applications have hugely variable (and uncontrollable) lighting conditions and therefore reliable, error-free object detection using optical sensors, due to all these factors, can be problematic.
A free-to-download White Paper from sensing and instrumentation specialists BAUMER considers all the challenges of why ambient light has such a significant influence on the performance of optical sensors and provides some practical solutions.
Topics include; why optical sensors are very prone to ambient light and why this happens,
what effect this can have on certain processes, the efforts in trouble-shooting and counter actions, overcoming these challenges, offering solutions and finally conclusions to be drawn.
Baumer also outlines the features and benefits of their latest range of optical sensors which provide reliable detection in any lighting conditions, including LED and bright sunlight.
Finally, the Baumer ‘sensor toolbox’ offers the next generation of optical sensors providing users with all the benefits of unrivalled ambient light immunity and hence
the ability to
eliminate many error sources in production. Download your copy at:

High-UV sensitivity, back-illuminated, digital CMOS area image H
amamatsu Photonics has introduced the new S16101 CMOS area image sensor. Designed with a back-illuminated structure and a 1280x1024 Active Pixel Sensor (APS) matrix, this sensor is suitable for applications not only in the visible spectrum, but also with spectral components in the Ultra Violet (UV) and near infrared (NIR). Featuring high-UV sensitivity from 200nm, this non-cooled CMOS

area image sensor delivers a spectral response to 1100nm and is stable in UV light irradiation. Its sensitivity makes it ideal for industrial applications such as the detection of glues or resins in quality control.
Due to the electronics integrated within the sensor including the built-in timing and bias generators, amplifiers and A/D converters, the output signal is now digital (LVDS). Additionally,
the S16101 can reach a high- reading speed of 146 frames per second due to a reduction in the number of pixels along the vertical axis. It is also possible to reduce the number of vertical pixels to further increase the readout speed.
Finally, on top of offering the choice
of rolling or global shutter readout, the new sensor utilizes industry-standard SPI communication comprising of partial readout, gain switching, frame start mode selection functions, and more.
