Targeting the defense industry’s VPX-based embedded computing systems that require increased bandwidth and radio frequency (RF) signaling, TE Connectivity has launched its line of NanoRF optical hybrid modules. These hybrid modules feature high-density RF and optical connections for common connector module applications in military applications such as radar, electronic warfare (EW) missile guidance and tactical communications.
They can be used in any small footprint applications where high-frequency RF and optical signals are critical, said TE.

The NanoRF optical hybrid modules support cable mechanical transfer (MT) and edge-mount transceivers, which provides additional modularity and options. In addition, intermateability and interoperability among VPX hardware suppliers is achieved thanks to multiple slot profiles and connector modules added to the VITA 65.0 and VITA 65.1 compliant backplanes and board-level profiles. The NanoRF optical hybrid modules are being defined in the VITA 66.5 draft standard, which is expected to be released in 2022.
A key design feature of the hybrid modules is a floating insert on the backplane side that contains both NanoRF contacts and optical MTs. This allows precise alignment of the RF contacts and MTs before engagement. This is said to enable the highest density in a VPX slot and reduce the potential for damage.
The connector modules provide a rated frequency of 85 GHz and a 50-ohm impedance. They are rated for 500 mating cycles and offer a mechanical temperature range of -55°C to 125°C. They are available in base-card and mezzanine edge mount or cable options.
