SN Uniboot

The SN Uniboot is a revolutionary connector that allows four duplex SN connectors to be patched simultaneously in one operation. Subsequently, the SN-Uniboot offers the same degree of flexibility as an MPO 8-fiber connector but without the need for breakout cassettes or fanout cables to transition from Base-8 to Base-2. This dual functionality makes the SN Uniboot granular enough for duplex server connections, optimized for high-density trunks and the perfect match to high data rate transceivers utilising four optical lanes (8 fibers).


  • TELCO grade ceramic ferrules
  • Base-8 and Base-2 patching flexibility
  • Push-pull Boot for simple installation and removal
  • Eliminate cassettes and fanouts
  • Quadrupled density versus LC duplex
  • Supports 400G data rates with QSFP-DD and OSFP transceivers

The SN Uniboot is only compatible with standard SN Footprint adapters with 4-Channels/Ports. This is because the connector comprises 4 x SN Connectors vertically aligned.

The SN has a unique housing that can be rotated 180 degrees allowing the four SN duplex connectors to be spaced further apart. This increased spacing allows connectors to be patched to shuttered adapters that have walls between each duplex connector. The operation is fast and simple and can be achieved in the field if required.​

The SN Uniboot is designed to fit QSFP-DD and OSFP transceivers. It has been designed so that it does not interfere with the latch of the transceiver, which can vary from vendor to vendor. ​

The connector has a push-pull uniboot design. The boot can be pushed when inserting the connector or pulled for automatic removal.

The SN Uniboot incorporate ceramic 8 x 1.25mm ferrules, whereas the MPO incorporates a single polymer ferrule. The SN Uni-boot allows 4 x duplex SN connectors to be broken out directly from the SN adapter. MPO requires a cassette or a fanout cable to break out the 8-fiber interface to 4 x duplex.

Yes, the SN interface is being standardized by the IEC.

Currently the SN Uniboot is only available as an 8-fiber connector. This is because Base-8 is the preferred configuration for parallel optics consisting of four lanes. Please contact our sales team if you have a special application not covered by our standard portfolio.

Assemblies can be made with SN-Uniboot at one end and MPO at the other end. This will allow users to patch from a SN-Uniboot patch panel to SR4 transceivers if necessary. ​

With SN Uni-boot patch cords it is impossible to ’shuffle’ fiber lanes across multiple transceivers. However, customised high-density trunk cables can be manufacturedwhich allow the ‘shuffling’ of fibers across four different SN-Uniboot connectors. Such an assembly would need to be constructed from at least 32 fibers in this case.​
