Expanded beam fibre optic connector for tough environments

An expanded beam fibre optic connector from HARTING is said to provide high bandwidth transmission in harsh environments, such as in tunnel drilling and mining applications – where according to HARTING industrial Ethernet over fibre optic cable is becoming the transmission medium of choice.

As digitisation makes increasing inroads into these sectors, the demands placed on the communication and control cabling become particularly stringent. Since optical interfaces are sensitive to contamination, a rugged and more reliable solution was needed.

The Expanded Beam Cable Assembly is said to allow the high definition video signals used in the vision systems that control the boring machines and associated equipment to be safely and securely transmitted.

According to the company, the fibre is packed in a connector housing that cannot be affected by dust, water or other environmental factors.

In addition, the company claims the hermaphroditic mating design of the expanded beam connectors ensures that regular disconnection and re-connection of the cabling in these environments is as simple as connecting an additional cable, with no need to pay attention to the laying direction or any additional adaptors.

In addition to applications in mining and tunnel boring machines, HARTING's Expanded Beam Cable Assembly can be used to link networks in other heavy-duty application areas, including outside broadcast events, concert and music festival stage installations and container ports.
