A REVOLUTION IN MANUFACTURE OF OPTICAL COMPONENTS
- An Active Optical Cable (AOC) is built from the optical head (the μTOSA/μROSA ) and an electronic chip that creates the interface between the optical chips (laser, detector) to the standard electrical interface such as HDMI, USB 3.0 and USB Type C and Ethernet.
- OTX has developed proprietary technology for the manufacture of the miniature version of the μTOSA/μROSA, the optical head.
- The most complex task when assembling the fibers to a laser diode or detectors is the alignment process. This has been addressed by OTX’s solution and applied on single mode fibers (SMF). SMFs currently cost 10-15% of the cost of multimode fibers (MMF) and offer superior performance in term of bandwidth over distance.
- However SMF are much more complicated to align as they require very high accuracy alignment (1μm) compared with 10 μm for 50 micron core MMF, the current competitive benchmark.
- OTX has overcome this barrier by successfully developing a process that enables the pre-alignment of the laser to the μTOSA/μROSA platform, enabling a subsequent easy attachment of the SMF by a non-skilled technician.
- μROSA chips can then be offered to any cable manufacturer to create a low cost, high quality and high speed AOC.
- The OTX technology permits single mode cables to be used, in consumer market applications, thereby enabling lower prices than MMF cables and benefitting from the technical advantages of the SMF cables.
- The new product configuration of OTX comprises :
a) PCB board, with 4 drivers
b) Metallic contact to the HDMI box,
c) 4 lasers
d) Groove to align the single mode cables in the assembly line.
