N4917BSCB 400G Optical Receiver Test Application—At a Glance
Compliance Tests for Optical Transceivers
The IEEE 802.3bs and IEEE 802.3cd standards define a series of
procedures to test the correct operation of optical transceivers at the
physical layer to ensure minimum required performance and
interoperability (see Figure 1 ). Keysight solution software are available for
each interface: Chip-to-module (C2M) interface including electrical
transmitter and receiver tests and the optical interface with transmitter
and receiver tests.

transceiver
In particular, the purpose of the optical receiver test is to test the receiver
sensitivity and jitter tolerance with a stress optical signal, whose
characteristics are defined by the standard. This stress signal is supposed
to emulate the signal coming out of a standard-compliant transceiver after
the worst possible optical channel.
N4917BSCB Optical Receiver Stress Test
N4917BSCB 400G Optical Receiver Test Application provides a platform
for stressed receiver sensitivity test, which is compliant to automated
standards for 200GBASE and 400GBASE Optical Receiver Stress Testing.
