Application Grid for Instrument Style Products

Applications listed are many of the most common "standard" telecom and datacom system definitions, along with the bit-rate they operate at.

The product column calls out those products specifically suited to operate as a system level receiver for the specified bit-rates. In this situation, the bandwidth of the receiver needs to fall in a fairly tight range. Too little bandwidth creates eye-closure problems, and too much bandwidth allows waveform artifacts to induce errors. These products have been designed to have an electrical bandwidth (in GHz) that is approximately 75-80% of the bit-rate (in Gb/s). This provides the best fidelity in a classic receive application.

For precise system and transmitter characterization to industry standards, we offer "Reference Receiver" options for several products at 2.5 Gb/s and 10 Gb/s bit-rates. These special receivers have their frequency and phase characteristics controlled to precise standards in order to produce a known or "reference" response against which other system components can be measured. These receivers also offer frequency response down to DC in order to enable accurate extinction ratio measurements within the system.

For diagnostic applications, where the user desires to see any artifacts that are present on the signal waveform, we recommend choosing a receiver with at least two to three times the normal receive bandwidth.
