Optical switch specialist CrossFiber says it has completed the final tranche of its Series D funding, bringing the total funding in the round to $13.4 million (€10.4 million). 


Southern Cross Venture Partners led the round, with participation from New Venture Partners, Arsenal Venture Partners and existing investors including Back Bay Management and PacifiCap.
The company said that the majority of the funds have been and will continue to be used for rapid expansion of manufacturing capacity, to meet the demand for its LiteSwitch family of 3D-MEMS-based photonic switches. The product family comprises all-optical switch modules, with up to 128 x 128 ports, but the company has plans to develop modules with up to 512 x 512 ports. It is targeting  applications in reconfigurable optical add-drop multiplexers (ROADMs), automated fibre crossconnects and subsystems for test and measurement.
CrossFiber also disclosed that it now “owns the entire patent portfolio, invention and lab notebooks, manufacturing knowhow and 2D-MEMS switch inventory of OMM”. Originally called Optical Micro-Machines, OMM was one of the pioneers in optical switching, having produced the first Telcordia-qualified MEMS-based photonic switch modules, but the start-up closed down in 2003. 
Interestingly, OMM was the first start-up to be founded and run by Hus Tigli, who left the company abruptly in 2001.  He joined CrossFiber the following year.
“We now own an even stronger IP portfolio and a deeper base of knowhow," said Tigli, who is president and CEO of CrossFiber.  "Our core technologies, combined with our innovations in automated manufacturing and testing of precision parts enable us to serve customers demanding performance, economical solutions and volume manufacturing.”
