Optical Receiver Stress Test Solution
N4917B
-
The N4917B software provides an automated standard compliant stressed receiver sensitivity test according to 100GBASE-LR4, ER4 and SR4 test specification. In order to do this kind of test, several test instruments such as a bit error ratio tester, digital sampling oscilloscope, optical reference transmitter and tunable laser source are required to operate together to achieve a compliant, repeatable optical stressed eye. This stressed eye is then fed to the receiver under test, where bit error ratio is measured under the stress conditions as defined in the standard.

Series Voltage References
-
Analog Devices offers a broad line of series voltage references with low dropout, low power, and excellent line regulation. These devices are voltage references that are functionally similar to a three-terminal regulator. Some series voltage references are designed to also operate in shunt mode by biasing the output pin and leaving the input pin open circuit. Series mode voltage references have the advantage that they draw only load and quiescent current from the input supply.
