Harting’s new PushPull SFP XS fibre-optic connector is designed to address the biggest challenge to the use of optical connectors in industrial environments: their susceptibility to contamination. Dirt on fibre end faces can damage the contact surfaces that form the interface with the transceiver, which can result in poor or unreadable signals.
Harting has developed an expanded beam fibre-optic connector for providing high-bandwidth transmission in the harsh environments found in tunnel drilling and mining applications, where industrial Ethernet over fibre-optic cable is becoming the transmission medium of choice.
The long distances involved, together with the high bandwidths that are required, make the use of fibre-optic cable essential, but since optical interfaces are very sensitive to contamination, a rugged and more reliable solution has to be devised.
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.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
