SHF provides a wide range of high performance digital high speed modules suitable for the use in telecommunication systems and test and measurement setups e.g. for SONET OC-768 / SDHSTM-256, 100 GbE, 400 GbE, 1TbE or Fibre Channel.
Raising the speed (up to 120 Gbps serial)
Our multiplexers (MUX) and demultiplexers (DEMUX) offer broadband operation up to 120 Gbps with adjustable output amplitude and eye symmetry.
Raising the number of levels (digital-to-analog converters 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 SHF 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 (PAM4 Multiplexer 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.
Signal Shaping
Our filter offer the crucial benefit of improving the quality of a heavily degraded signal after transmission, e.g. for BER measurements. Equalizing operation has been verified for signals up to 60 GBaud PAM4 and 80 Gbps NRZ.
Tailor it to the needs
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.
