Split/combine optical fibre signals without a beam splitter

October 22, 2015 // By Graham Prophet
These ‘Spider’ fibre optic cable assemblies can both split an optical signal from a single source into several outputs, or combine multiple inputs onto a single output fibre. This can be useful for sensor applications and precise triggering, among other applications.

Previously, designers have been forced to use beam splitters for this purpose, but such devices can be expensive as well as complex to set up. OMC’s ‘Spider’ fibre optic assemblies are positioned as rugged, reliable and much more cost effective. Perhaps the most important feature is that the spider assemblies can be manufactured to suit the engineer’s application, with specific lengths, connectors and numbers of input/output channels.

As an optoelectronics problem solvers, OMC relates that it was approached by two companies, one which needed to combine several high output sources of various wavelengths for a sensor application, and the other which was looking at simultaneously triggering multiple receivers from a single source; its core technologies were applied to provide a “simple, effective solution.”

Machine vision systems and data-communications equipment are example applications where the company has applied the spider assemblies; “...any number from 2-47 ends from a single input - or the reverse... [in] glass or polymer fibre and using any standard diode or housing.” The company can produce modular systems for prototyping.
