Further Information

SHF provides a wide range of high speed modules suitable e.g. for SONET OC-768 / SDHSTM-256, 100 GbE, 400 GbE, 1TbE or Fibre Channel telecommunication systems . The needs of our customers are different; therefore SHF is happy to offer customization to specific applications. A small selection of such assemblies based on our standard product offerings can be found in the customized assemblies subsection.

Raising the speed (up to 120 Gbps serial)

Our multiplexers (MUX) and demultiplexers (DEMUX) offer broadband operation up to 120 Gbps with adjustable amplitude and eye symmetry.

Raising the number of levels (up to 60 GBaud)

Our digital-to-analog converters (DAC) operate at baud rates up to 32 or 60 GBaud. Up to six single-ended serial data streams are converted into one differential multi-level signal. This makes the DAC an ideal electrical signal source e.g. for PAM or QAM applications. Together with one of our our programmable BPGs (Bit Pattern Generators) a high speed “remote head” AWG (Arbitrary Waveform Generator) is formed.

Raising the speed and the number of levels (up to 128 GBaud)

Our PAM4 multiplexer take four binary input data streams, re-time, reshape the signals and multiplex each two to a binary signal of double the speed. Inside the module a two bit DAC converts these two extremely high speed signals to a four level signal.
